The history goes back to 2001 or so, but everyone involved with still
existing code has agreed.
One person who could not be reached yet (elevengu) has changes in this,
which as far as I can tell were overwritten anyway at a later point.
If you do "mpv /bla/", and then branch out into sub-directories using
playlist navigation, and then used quit and watch later, then playing
the same directory did not resume from the previous point. This was
because resuming is based on the path hash, so a path prefix can't be
detected when resuming the parent directory.
Solve this by writing each path prefix when playing directories is
involved. (This includes all parent paths, so interestingly, "mpv /"
would also resume in the above example.)
Something like this was requested multiple times, and I want it too.
mp_find_config_file() will print the filename lookup and its result in
verbose mode. This is wanted, but gets inconvenient when it is done for
every playlist entry (for resuming).
Lookup the watch_later subdir only once and cache the result instead.
This drops the logic for loading the resume file from other locations,
which should generally be unnecessary, though might lead to confusion if
the user has mixed old and new config paths (which the user shouldn't).
Also add a mp_find_user_config_file() function for a more
straightforward and reliable way to get actual local configpaths,
instead of possibly global and unwritable locations.
Also, for symmetry, check the resume option in mp_load_playback_resume()
just like mp_check_playlist_resume() does.
Actually, it's pretty simple to look for multiple filenames at once,
since mp_find_all_config_files() is already a bit "special" anyway.
See #1569. Reverts most of commit db167cd4 (keeps osx-bundle.conf).
bstr.c doesn't really deserve its own directory, and compat had just
a few files, most of which may as well be in osdep. There isn't really
any justification for these extra directories, so get rid of them.
The compat/libav.h was empty - just delete it. We changed our approach
to API compatibility, and will likely not need it anymore.
Search $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS for config files.
This also negates the need to have separate user and global variants of
mp_find_config_file()
Closes#864, #109.

Including the "." in the returned extension was too inconvenient. I
think originally, the semantics were supposed to work like in Python,
but screw this.
Also, return NULL instead of "" on failure (which is what its only user
actually seems to expect).
There's a single mp_msg() in path.c, but all path lookup functions seem
to depend on it, so we get a rat-tail of stuff we have to change. This
is probably a good thing though, because we can have the path lookup
functions also access options, so we could allow overriding the default
config path, or ignore the MPV_HOME environment variable, and such
things.
Also take the chance to consistently add talloc_ctx parameters to the
path lookup functions.
Also, this change causes a big mess on configfiles.c. It's the same
issue: everything suddenly needs a (different) context argument. Make it
less wild by providing a mp_load_auto_profiles() function, which
isolates most of it to configfiles.c.
Since m_option.h and options.h are extremely often included, a lot of
files have to be changed.
Moving path.c/h to options/ is a bit questionable, but since this is
mainly about access to config files (which are also handled in
options/), it's probably ok.
