keyword searches and synctex forward search.

This way we get rid of page_calculate_offset that involves explicit GTK
calls. Also, we can make use of page_number_to_position to align page
and viewport as desired.
I've also tried to make the code for this function a bit more readable.
The new page_set and position_set behave as delayed, but with the
immediate availability of the new positions through the document
object. We no longer need to keep delayed and non-delayed versions!
This new function adjust_view is in charge of recomputing the scale
according to adjustment settings and trigger a render_all.
adjust_view contains the old sc_adjust_window code, slightly simplified
thanks to the availability of the document_get_viewport_size.
Then it is used by sc_adjust_window, document_open and the
cb_view_resized callback. Makes slightly more sense this way than
calling the shortcut sc_adjust_window directly.
Since we 'continue' the loop if num_search_results is 0, there is no need for
the second check.

This patch adds a new configuration setting, selection-clipboard, which allows
us to choose between the PRIMARY selection, and the CLIPBOARD selection, for
determining which X clipboard to use for storing mouse-selected data. It has
only two valid values: "primary" and "clipboard", with "clipboard" being set as
the it's default value.

Otherwise, when opening a document at page 1, and no jumps are added,
bisect does not understand it has to initialize the bisect range, and
does not move from page 1.

After page_set cb_view_hadjustment_changed must be called so that when
zoom-center is enabled, the page is recentered.

- Allow the user to always start with the very last (or first) jump on the
jumplist when pressing ^o (or ^i), while the jumplist iterator is
pointing to the last (or first) jump, and the document is not currently
at the position of this pointed-to jump. This is instead of jumping
directly to the previous/next jump, and skipping the last/first one.
- Don't jump to the current jump pointed to by the jumplist iterator, if
there is no more next jumps, and the jump direction is FORWARD.
- Don't jump to the current jump pointed to by the jumplist iterator, if
there is no more previous jumps, and the jump direction is BACKWARD.

- Don't delete the elements on the right of the current one, when
appending a new jump to the jumplist, because this makes no sense at
all; the point of the jumplist in the first place is to remember
previously jumped-to positions in the document, so there is no need
to delete anythings except to trim the oldest entries from the
beginning to maintain the maximum size. This also makes us compatible
with the Vim way of doing things.
- Make the jumplist mechanism functional on the same page; if we
followed a link to a target on the same page, remember the
adjustments before and after following the link. The same holds for
navigating search results on the same page.
- Implement position_set and use it instead of position_set_delayed
when following links in order to give zathura_jumplist_save a chance
to record the exact adjustments of the link target. Otherwise, it
will always record the adjustments after going to the target page,
but before going to the exact position within it.
- Don't consider movements with ^i and ^o as jumps :)
- Don't use page_set followed by setting the adjustments in
sc_jumplist, because this is redundant and causes clutter when using
^i and ^o, as the adjustments is set twice this way (once in page_set
and again in position_set_delayed). It's enough to only update the
page number on the statusbar and then set the adjustments.
- Hide implementation details (zathura_jumplist_save and
zathura_jumplist_append), and make things more consistent by
exporting and using only zathura_jumplist_add for adding new entries.
The end result: A more slick jumping experience :-)

This patch activates the last aborted search when pressing the search shortcuts
('n' or 'N').
To avoid confusion, and to make things more predictable, I've chosen to always
reactivate an aborted search starting from the beginning (or end, in case of
'N' or '?') of the current page, as opposed to Vim which continues from the
next search term each time the search is reactivated.
Searching using '/' or '?' doesn't center the view at the current search term
like when using 'n' or 'N', so we fix this here.
Also, I managed to work around the issue of the thin rectangular margins that
show around the previously-highlighted search terms after the search is aborted
(either explicitly or as a result of following links), by redrawing the page
widget (only if it's visible) instead of redrawing the rectangles covering the
highlighted search terms.

This uses the jumplist to implement a bisect functionality between the
last two jump points. ^j and ^k are bound to bisect forward and backward
respectively.
