* src/vte.c (vte_terminal_match_check_internal): snip off final newlines when
	we're matching, they're usually not wanted.
* src/pty.c, src/pty.h: replace the simpler pty_open() function with a logging
	version, adding the ability to specify a startup directory (Red Hat
	#76529).
* src/vte.c, src/vte.h: replace the simpler fork_command() function with a
	logging version, adding the ability to specify a startup directory (Red
	Hat #76529).
* src/vteapp.c: modify call to handle new fork_command().
* python/vte.defs: update as above.
* python/vte.override: modify call to handle new fork_command(), adding an
	optional "directory" argument.
* src/vte.c: refactor the selection code, cleaning up when selection is
	cleared/started/extended (#95783).  Grab focus whenever we get button
	press or release or motion events.
* src/vte.c: rework how wide characters are stored to allow storing tabs
	(#95958).
* python/vte.override: wrap vte_terminal_get_text() and
	vte_terminal_get_text_range().  Based on patch from ha shao (#96230).
* src/vte.c, src/vte.h: add a user pointer argument to get_text callbacks
	(#96230).
* src/Makefile.am: bump shared library version because we changed a public
	function's signature.  Take the opportunity to replace padding fields
	which had previously been used up.
