The license text refers a "above copyright notice", so I guess it'd be
good to actually provide such a notice.
Add the license to some files that were missing it (since in theory, our
Copyright file says that such files are LGPL by default).
Remove the questionable remarks about the license in the client API.

The NULL check triggers a gcc warning when passing the address of a
variable to it. I was about to silence the warning with some equivalent
code (that just happens to shut up gcc), but then I decided to remove
the NULL check as I don't see a reason why we should allow this. We
don't use it in the existing code anyway (all callers do something like
TA_FREEP(&structptr->member), which is always non-NULL).
Also fix some of the macro argument "quoting".

This fixes the build in mingw-w64/Clang on MSYS2. It also disables the
use of gnu_printf in Clang, which was what was causing most of the
warnings. The Clang-compiled mpv binary appears to work, but there are
no guarantees yet, since until now mpv has only been tested with
mingw-w64/GCC on Windows.
Fixes #3800

This sets the pointer to NULL after talloc_freeing it. This emulates the
av_freep function for ta_talloc, but with a macro instead.

* Adds an 'android' feature, which is automatically detected.
* Android has a broken strnlen, so a wrapper is added from FreeBSD.

The macro actually returns the *available* space in the array, not how
much is actually filled in.

In all of these situations, NULL is logically not allowed, making the
checks redundant.
Coverity complained about accessing the pointers before checking them
for NULL later.

If this function could return the input value (i.e. the == case was
correct), then macros like MP_GROW_ARRAY would have been incorrect. The
implementation was correct though, so there's no bug.

Not really cargo cult, but an unexplainable, needless difference that
just exists to annoy us.
Fixes that gcc on MinGW treats format specifiers in MSVC mode. Just why?
Why?

There are multiple reasons to do this. One big reason is the license:
talloc is LGPLv3+, which forces mpv to be licensed as GPLv3+.
Another one is that our talloc copy contains modifications, which makes
it essentially incompatible with upstream talloc (in particular, our
version aborts on out of memory conditions - well, it wasn't my idea).
Updating from upstream is also a bit involved - the talloc source is
not really organized in a way to allow copying it into projects (and
this isn't an intended use-case).
Finally, talloc is kind of big and bloated. The replacement halves the
amount of code - mainly because we didn't use all talloc features. It's
even more extreme if you compare upstream talloc (~4700 lines) and the
new allocator without talloc compat (~900 lines).
The replacement provides all features we need. It also doesn't clash
with talloc. (The talloc compatibility wrapper uses macros to avoid
introducing linker-level symbols which could clash with libtalloc.)
It also tries to lower the overhead (only 4 words opposed to 10 words
in talloc for leaf nodes in release mode). Debugging features like leak
reporting can be enabled at compile time and add somewhat more overhead.
Though I'm not sure whether the overhead reduction was actually
successful: allocations with children need an "extra" header, which adds
plenty of overhead, and it turns out that almost half of all allocations
have children. Maybe the implementation could be simplified and the
extra header removed - even then, overhead would be lower than talloc's.
Currently, debugging features can be entirely deactivated by defining
NDEBUG - I'm not sure if anything defines this directly yet, though.
Unlike in talloc, the leak reporting stuff is thread-safe. (That's also
why it's far less elegant, and requires extra list pointers.)
Comes with a compatibility layer, so no changes to mpv source code
are needed. The idea is that we will pretend to be using talloc for
a while, so that we can revert to our old talloc implementation at
any time for debugging purposes.
Some inspiration was taken from Mesa's ralloc:
http://cgit.freedesktop.org/mesa/mesa/tree/src/glsl/ralloc.h
This is another talloc replacement, but lacks some features we need
(getting size of an allocation, debugging features, being able to
access children in the dtor).
There's some information in ta/README what will happen next and how the
transition is expected to progress.
