wm4 cc54377463 Do not call strerror()
...because everything is terrible.

strerror() is not documented as having to be thread-safe by POSIX and
C11. (Which is pretty much bullshit, because both mandate threads and
some form of thread-local storage - so there's no excuse why
implementation couldn't implement this in a thread-safe way. Especially
with C11 this is ridiculous, because there is no way to use threads and
convert error numbers to strings at the same time!)

Since we heavily use threads now, we should avoid unsafe functions like
strerror().

strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and
gives the function different semantics than the POSIX one. It's a bit of
work to convince this piece of shit to expose the POSIX standard
function, and not the messed up GNU one.

strerror_l() is also in POSIX, but only since the 2008 standard, and
thus is not widespread.

The solution is using avlibc (libavutil, by its official name), which
handles the unportable details for us, mostly. We avoid some pain.

wm4 12212a1685 common: fix version variable declarations
This was stupid.

wm4 68ff8a0484 Move compat/ and bstr/ directory contents somewhere else
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.

wm4 3c322b1022 common: change MP_NOPTS_VALUE definition
Use the exact floating point value, instead of a broken integer
constant. The expression calculating the constant probably relied on
undefined behavior, because it left-shifts a negative value.

This also changes the type of the constant to double, which is perfectly
fine, and maybe better than an integer constant.

wm4 a8b267540e common: change mp_snprintf_append semantics
Make it more suitable for chaining. This means a function formatting a
value to a string using a static buffer can work exactly like
mp_snprintf_append itself.

Also rename it to mp_snprintf_cat, because that's shorter.

wm4 066ecfcbfb common: simplify and optimize string escape parsing
This code is shared between input.conf parser and option parser. Until
now, the performance didn't really matter. But I want to use this code
for JSON parsing too, and since JSON will have to be parsed a lot, it
should probably try to avoid realloc'ing too much.

This commit moves parsing of C-style escaped strings into a common
function, and allows using it in a way realloc can be completely
avoided, if the already allocated buffer is large enough.

wm4 e6bea0ec5a Don't include version.h from make options.c
I find this annoying. It's the reason common/version.c exists at all.

options.c did this for the user agent, which contains the version
number. Because not including version.h means you can't build the user
agent and use it in mp_default_opts anymore, do something rather awkward
in main.c to initialize the default user agent.
