### Motivation
Closes#5512.
The issue was introduced in #4445. It's needed to add checking the
redirect case.
### Before
```xsh
cd /tmp
@aliases.register('a')
def _a():
print("1-hello")
echo 2-hello
a > o.txt
# 2-hello
cat o.txt
# 1-hello
```
### After
```xsh
cd /tmp
@aliases.register('a')
def _a():
print("1-hello")
echo 2-hello
a > o.txt
cat o.txt
# 1-hello
# 2-hello
```

To have clear `./xonsh` directory with the list of components we need to
move common packages that are not components of xonsh to lib directory.
cc #5538
I see that `lib.os` and `lib.subprocess` have a bit different intention.
I think more clearer will be put them to `xonsh.api`. This is the first
step to #5383.

### Motivation
I noticed that when I type every letter in the prompt on the remote
server the typing is lagging. I thought it's ssh but no.
After inspection the commands cache code I found that on every key press
there is reading all 2000+ files in PATH because the code for cache
update has funny issue.
### Quiz
```xsh
def f():
print(1)
yield False
print(2)
yield True
print(3)
print(any(f()))
```
What will be in the output? Answer:
<details>
```
1
2
True
```
The execution of `print(3)` ignored because `any()` interrupts the
execution of the function.
If we call `print(list(f()))` the output will be `1 2 3 [False, True]`.
</details>
### Before
* Updating cache (read all files in PATH and list of aliases) two times
after start.
* Updating cache (read all files in PATH and list of aliases) on every
key press in prompt.
### After
* Update cache once at start.
* Update cache only when we have real changes of paths or aliases.

### Motivation
Add `spec.raise_subproc_error` to have an ability to use
`SpecModifierAlias` to manage the errors. Also this is the first step to
#4351.
Generally in scripts it's good to have RAISE_SUBPROC_ERROR=True to avoid
processing the error for every executed command. But in some cases (e.g.
`![]`) it's needed to avoid raising the error. To more elegant doing
this we can make an ability to create SpecModifier.
### After
```xsh
from xonsh.procs.specs import SpecModifierAlias
class SpecModifierNoErrAlias(SpecModifierAlias):
def on_modifer_added(self, spec):
spec.raise_subproc_error = False
aliases['noraise'] = SpecModifierNoErrAlias()
$RAISE_SUBPROC_ERROR = True
if ![noraise git pull]:
git add --all
```

After #5491 there is one case unfixed:
### Before
```xsh
echo 'echo home' >> ~/.xonshrc
cd /tmp
echo 'echo script' > 1.xsh
xonsh 1.xsh
# all rc without ~/.xonshrc
# script
xonsh -i 1.xsh
# all rc without ~/.xonshrc # bug
# script
```
### After
```xsh
echo 'echo home' >> ~/.xonshrc
cd /tmp
echo 'echo script' > 1.xsh
xonsh 1.xsh
# all rc without ~/.xonshrc
# script
xonsh -i 1.xsh
# all rc with ~/.xonshrc
# home # FIX

Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
### Motivation
In #5099 was introduced the logic where all RC files are loaded in
interactive and non-interactive modes. This logic is not working good
for home based `~/.xonshrc` file.
First of all `~/.xonshrc` is the buffer/accumulator of settings focused
on interactive mode. Most tools with integration with xonsh (e.g.
`conda`, `zoxide`, etc) offer to just do `echo "init_tool()" >>
~/.xonshrc` (`conda` has around 20 lines of init code) to start using
the tool and users are doing this without any doubts.
But because of after 5099 `~/.xonshrc` is executed in non-interactive
mode the adding code to it leads to unexpected and unintended side
effects:
* If you run a script with shebang (e.g. `#!/usr/bin/env xonsh` or
[xonsh-awesome-cli-app](https://github.com/anki-code/xonsh-awesome-cli-app))
or just from `xonsh script.xsh` the code will be unexpected and
unintended slower.
* If you're using xonsh-based tools (e.g. you install them using pip)
and run them in environment that has no packages that initiated in
`~/.xonshrc` you will see epic errors.
* Additional context:
* Bash and Zsh do not load `~/.bashrc` and `~/.zshrc` in non-interactive
mode by the same reasons.
* We have welcome message `Create ~/.xonshrc file manually or use xonfig
to suppress the welcome message` and we don't want to make the process
of creating this file complex.
All of this leads to bad unexpected and unintended experience. This PR
is to fix this.
### Expectation
By doing this fix we assume that experienced user who wants to build
good repeatable run control files will use another ways to create config
files and this has [reflection in
docs](8860f2bd52/docs/xonshrc.rst).
In the nutshell if you want to create the RC files that affect every run
of code you should use one or many of these ways:
* Cross-desktop group (XDG) compliant `~/.config/xonsh/rc.xsh` control
file.
* The system-wide control file `/etc/xonsh/xonshrc` for Linux and OSX
and in `%ALLUSERSPROFILE%\xonsh\xonshrc` on Windows. It controls options
that are applied to all users of Xonsh on a given system.
* The home-based directory `~/.config/xonsh/rc.d/` and system
`/etc/xonsh/rc.d/` can contain .xsh files. They will be executed at
startup in order. This allows for drop-in configuration where your
configuration can be split across scripts and common and local
configurations more easily separated.
In your configs you need to check `$XONSH_INTERACTIVE` and
`$XONSH_LOGIN` explicitly.
### Before
`~/.xonshrc` is used in non-interactive mode.
```xsh
echo "echo RC" >> ~/.xonshrc
cd /tmp
echo "echo Script" > script.xsh
xonsh script.xsh
# RC
# Script
```
```xsh
cd /tmp
echo 'echo RC' >> ~/.xonshrc
echo '#!/usr/bin/env xonsh' > myscript
chmod +x myscript
./myscript
# RC
```
### After
`~/.xonshrc` is not used in non-interactive mode. Use `-i` if you need
it.
```xsh
echo "echo RC" >> ~/.xonshrc
cd /tmp
echo "echo Script" > script.xsh
xonsh script.xsh
# Script
xonsh -i script.xsh
# RC
# Script
```
```xsh
cd /tmp
echo 'echo RC' >> ~/.xonshrc
echo '#!/usr/bin/env xonsh' > myscript
chmod +x myscript
./myscript
```
Closes#5488#4096#5496
### Fun
I want to leave here some nice representation of how it works in
bash/sh/zsh from [twitter
post](https://twitter.com/paxx39/status/1742768007154479109):

This is continuation for introduced before
`$XONSH_SUBPROC_OUTPUT_FORMAT` (#5377) so news file is not needed.
### Motivation
Having `output_format` in spec and in pipeline allows to switch output
format in `SpecModifierAlias` and during non-blocking work e.g.
```xsh
p=!(echo '1\n2\n3')
p.output_format = 'list_lines'
p.out
# ['1','2','3']
```
```xsh
from xonsh.procs.specs import SpecModifierAlias
class SpecModifierOutputLinesAlias(SpecModifierAlias):
def on_modifer_added(self, spec):
spec.output_format = 'list_lines'
aliases['xlines'] = SpecModifierOutputLinesAlias()
$(xlines echo '1\n2\n3')
# ['1','2','3']
```

### Motivation
This is fix for introduced before
`$XONSH_SUBPROC_OUTPUT_FORMAT='list_lines'` so news file is not needed.
We should return the list for single line output to avoid unintended
reading the string.
### Before
```xsh
$XONSH_SUBPROC_OUTPUT_FORMAT='list_lines'
mkdir -p /tmp/list_lines
cd /tmp/list_lines
touch 123
du $(ls)
# 0 123
for f in $(ls):
print(f)
# 1
# 2
# 3
touch 321
for f in $(ls):
print(f)
# 123
# 321
```
### After
```xsh
$XONSH_SUBPROC_OUTPUT_FORMAT='list_lines'
mkdir -p /tmp/list_lines
cd /tmp/list_lines
touch 123
du $(ls)
# 0 123
for f in $(ls):
print(f)
# 123
touch 321
for f in $(ls):
print(f)

https://github.com/xonsh/xonsh/issues/5466 - and we need to fix parser
instead of resolver.

previously, this succeeded in CI, but always failed locally with the
following error:
```xsh
_____________________________________________________________________ test_raise_subproc_error_with_show_traceback[True] _____________________________________________________________________
monkeypatch = <_pytest.monkeypatch.MonkeyPatch object at 0x76f6ba8882e0>, interactive = True
@skip_if_on_windows
@pytest.mark.parametrize("interactive", [True, False])
def test_raise_subproc_error_with_show_traceback(monkeypatch, interactive):
out, err, ret = run_xonsh(
"$COLOR_RESULTS=False\n$RAISE_SUBPROC_ERROR=False\n$XONSH_SHOW_TRACEBACK=False\nls nofile",
interactive=interactive,
single_command=True,
)
assert ret != 0
> assert re.match("ls.*No such file or directory\n", out)
E assert None
E + where None = <function match at 0x76f6bcd0cd30>('ls.*No such file or directory\n', "\x1b]0;ls | jyn@pop-os: ~/src/xonsh | xonsh\x07ls: cannot access 'nofile': No such file or directory\n")
E + where <function match at 0x76f6bcd0cd30> = re.match
tests/test_integrations.py:1190: AssertionError
```
the problem was that the following string was prepended before the error
message:
```
\x1b]0;ls | jyn@pop-os: ~/src/xonsh | xonsh\x07l
```
that in turn came from
[`BaseShell.settitle`](66c0490d37/xonsh/base_shell.py (L570)),
which always prepends at least the escape codes even when TITLE is set
to an empty string.
avoid this issue by mimicking a dumb terminal in tests, in which case
`settitle` doesn't add any title at all.

### Motivation
* We have no recommended way to force subprocess command be
(un)threadable
* #4214
* #2119
* #5003
* It's interesting opportunity to have a way to modify specs and CP
using `SpecModifierAlias`.
### Before
```xsh
!(ssh host -T "echo 1")
# output='' # EXPECTED: 1
__xonsh__.commands_cache.threadable_predictors['ssh'] = lambda *a, **kw: True
!(ssh host -T "echo 1")
```
### After
```xsh
xthread
# Mark command as threadable.
!(xthread ssh host -T "echo 1")
# output='1'
```
Closes:
* Closes#4214
* Closes#2119
* Partially closes#5003
Implementation of `SpecModifierAlias` will help in:
* #2618
JFYI #5413

### Motivation
Closes#5003
### The case
Core utils in Nix are symlinks to one binary file that contains all
utils:
```xsh
docker run --rm -it nixos/nix bash
which echo
# /nix/store/k6h0vjh342kqlkq69sxjj8i5y50l6jfr-coreutils-9.3/bin/echo
ls -la /nix/store/k6h0vjh342kqlkq69sxjj8i5y50l6jfr-coreutils-9.3/bin/
# b2sum -> coreutils
# base32 -> coreutils
# ...
# All tools are symlinks to one binary file - `coreutils`.
```
When
[`default_predictor_readbin`](61bda708c9/xonsh/commands_cache.py (L392))
read `coreutils` it catches `(b'isatty', b'tcgetattr', b'tcsetattr')`
and return `threadable=False` forever.
The list of Nix coreutils tools are exactly the same as in [brew
coreutils](https://formulae.brew.sh/formula/coreutils). So I can check
the real predicts on distinct binaries and see that only 2 tools among
106 are unthreadable and they already covered by
`default_threadable_predictors` (If it's wrong please add unthreadable
tools to the
[default_threadable_predictors](61bda708c9/xonsh/commands_cache.py (L518))):
```xsh
brew install coreutils
ls /opt/homebrew/opt/coreutils/libexec/gnubin/ | wc -l
# 106
for t in p`/opt/homebrew/opt/coreutils/libexec/gnubin/.*`:
if not (th := __xonsh__.commands_cache.predict_threadable([t.name])):
print($(which @(t.name)), th)
# /opt/homebrew/opt/coreutils/libexec/gnubin/cat False
# /opt/homebrew/opt/coreutils/libexec/gnubin/yes False
defaults = __import__('xonsh').commands_cache.default_threadable_predictors().keys()
defaults['cat']
# <function xonsh.commands_cache.predict_false>
defaults['yes']
# <function xonsh.commands_cache.predict_false>
```
So the rest of we need is to check the symlink and apply default
prediction if the tools is the symlink to coreutils. This implements
this PR. Test included.
