The configure followed 5 different convetions of defines because the next guy
always wanted to introduce a new better way to uniform it[1]. For an
hypothetic feature 'hurr' you could have had:
* #define HAVE_HURR 1 / #undef HAVE_DURR
* #define HAVE_HURR / #undef HAVE_DURR
* #define CONFIG_HURR 1 / #undef CONFIG_DURR
* #define HAVE_HURR 1 / #define HAVE_DURR 0
* #define CONFIG_HURR 1 / #define CONFIG_DURR 0
All is now uniform and uses:
* #define HAVE_HURR 1
* #define HAVE_DURR 0
We like definining to 0 as opposed to `undef` bcause it can help spot typos
and is very helpful when doing big reorganizations in the code.

mplayer.c was a bit too big. Split it into multiple files. I hope the
way it's split makes sense. Maybe some things don't make too much sense,
or go against intuition. These will fixed as soon as I notice them.
Some files are a bit questionable (misc.c, osd.c, configfiles.c), and
suggestions how to organize this better are welcome.
Regressions are possible due to reorganized include statements.
Obviously I didn't just copy mplayer.c's orgy of include statements, but
recreated them for each file. It's easily possible that there are
oversights and mistakes, which will show up on other platforms.
There is one actual change: the public avutil.h include is removed from
encode.h, and I tried to replace most FFMIN/FFMAX/av_clip uses. I
consider using libavutil too much as dangerous, because the set of
include files they recursively pull in is rather arbitrary and is
different between FFmpeg and Libav.
Remove the ifdef hell from mp_find_user_config_file(). Move the win32
specific code (for MinGW and Cygwin) to path-win.c. The behavior should
be about the same, but I can't be sure due to lack of testing and
because the old path.c code was hard to follow. (I expect those who care
about windows will fix things, should issues pop up - sorry.)
One difference is that the new code will always force MPV_HOME. It looks
like the old code preferred the mpv config dir in the exe dir if it
exists.
Also, make sure MP_PATH_MAX has enough space, even if the equivalent
wchar_t string is not 0-terminated with PATH_MAX (because apparently the
winapi doesn't require this). (Actually, maybe we should just kill all
uses of PATH_MAX/MP_PATH_MAX.)
The homepath variable was static, and its value was set to a stack
buffer. This means a second invocation of the function would trigger
undefined behavior. Moreover the stack buffer always went out of scope
before homepath was used.
Previously, mpv incorrectly used the %HOME% environment variable on
MinGW to determine the current user’s home directory. This is wrong;
the correct variable to use would be %HOMEPATH%, which would however
still be wrong since application data goes into the application data
directory, not the user’s home. This patch makes it use the local
AppData path instead of reading an environment variable.
This however exposed another problem (which also affected users who
actually had the %HOME% variable set):
b2c2fe7a37 (discussed in issue #95) introduced some changes that
make mpv load user config files from the executable path on Windows.
The problem with this change is that config_dir was still declared
static, so once a config file had been found in the executable path,
it would set config_dir to an empty string, so mpv would dump e.g.
watch_later data straight into the user’s home. This commit also
fixes that.
One side effect of this is that mpv no longer considers the “mpv”
subdirectory in the executable path (that behavior resulted from
the homedir variable always being empty), unless it is somehow
unable to determine the local AppData path.
The previous check just searched for a "://" substring. This was quite
bad, because "://" can be a valid part of a path. Later, I added
special handling for filenames starting with "." and "/", so that you
could reliably pass arbitrary filenames to mpv, no matter how messed
up they were.
Even though it doesn't really matter in practise anymore, this is still
crap, so add a more reliable check instead.
core is used in many unix systems for core dumps. For that reason some tools
work under the assumption that the file is indeed a core dump (for example
autoconf does this).
This commit just renames the files. The following one will change all the
includes to fix compilation. This is done this way because git has a easier
time tracing file changes if there is a pure rename commit.
