Commit 3c825eb001 adds a field called `execpath` to the `aa_log_record` struct. This field was added in the middle of the struct instead of the end, causing an ABI break in libapparmor without a corresponding major version number bump.
Bug report: https://bugs.launchpad.net/apparmor/+bug/2083435
This is fixed by simply moving execpath at the end of the struct.

It doesn't make sense to expose the *_raw functions or the varg version
of aa_change_hatv to higher-level languages. While technically a breaking
change, the generated bindings for these functions never actually worked
anyways:
- aa_change_hat_vargs uses C varargs, which SWIG passes in NULL for by
default. It does not attempt to process the passed-in arguments at all
(and in fact caused an unused-argument compiler warning when compiling
the generated bindings).
- aa_getprocattr_raw and aa_getpeercon_raw both place output into a ``char
**mode`` pointer. SWIG by default generates these as opaque pointer
object arguments, rendering them unusable for getting output. Future
patches would be needed to fix ``char**`` arguments for the other functions
that use them. Moreover, these functions expect their caller to handle
memory allocation, which is also not possible from a higher-level
language point of view.

This patchset adds annotations so that SWIG can automatically manage the memory lifetimes of aa_log_record objects, and ensures proper cleanup is done in the %exception handler.
This is the first of a sequence of MRs to overhaul the SWIG bindings and fix pieces that never actually worked in the first place. As fixing those other pieces will require breaking changes, I am separating out the non-breaking changes into separate MRs.

Swig generates a "thisown" attribute, which is an escape hatch in case
higher-level code does something weird and needs to tell SWIG whether to
free the C object when Python garbage collects it. Adding this attribute
is not a breaking change w.r.t access to the other attributes of the parsed
record.

Unfortunately SWIG_exception does not support throwing OSError, so this
still requires Python-specific code.
Unlike just returning NULL, this will clean up intermediate allocations.

Tested by using Valgrind's Helgrind and DRD against the reentrancy test that I wrote: they both report no errors with the changes while reporting many errors with the old versions.
Commits "Inline _parse_yacc in libaalogparse" and "Make parse_record take a const char pointer since it never modified str anyways" have a tiny potential to be backwards-incompatible changes: I have justified why they shouldn't be in the commit messages, but it's worth looking over in case I was mistaken and we need to back those out.

... without all the profiles generated by the gen-*.py scripts.
This target is meant for local manual testing, especially when working
on additional simple_tests profiles.
It makes local testing much faster (15 seconds for ~2k profiles vs.
several minutes for the additional ~70k profiles generated by gen-*.py)
Needless to say that the CI should continue to use the parser_sanity
target that includes all the generated profiles.

The entry AA_RECORD_SYNTAX_V1 is only there for API compatibility reasons.
If we wanted to remove it, we could just renumber the other two entries
to preserve ABI compatibility. However, it seems easier to just delete the
entry if we ever break backcompat with a libapparmor2.

This function was only ever called once inside libaalogparse.c, and it looks
simple enough to not need to be split out into its own helper function.
As this function was never exposed publicly in installed header files, removing it
is not a breaking API change.

When the profile already contains a "file" rule containing the owner
prefix and the tool is trying to handle a new file entry, it tries to
show it in the logprof header as "old mode".
The issue is that when the owner rule is an implicit all files
permission, then the object "FileRule" is used instead of the set of
permissions. When subtracting FileRule from set() a TypeError
exception is thrown.
Fix this by "translating" FileRule.ALL perms to "mrwlkix".
