Do not fail audio decoding with avcodec_decode_audio3 if user has set a
custom get_buffer. Strictly speaking, this was never allowed by the API,
but it seems that some software packages did so anyways. In order to
unbreak applications (cf. http://bugs.debian.org/655890), this change
clarifies the API and overrides the custom get_buffer() with the defaults.

This change is inspired by a similar
commit (c3846e3e) in FFmpeg.

Current code would just return uninitialized data with no way
to detect this condition.
Instead, fill the whole GUID with 0 in that case.

Reference decoder clips data before shifting it to final range and also
forces 32-bit lossy mode to be actually 24-bit lossy mode in order to be
able to perform proper clipping.

Fix gcc warning:
ffplay.c: In function ‘toggle_full_screen’:
ffplay.c:2792:9: warning: unused variable ‘i’ [-Wunused-variable]

Fixes ticket 705.

This reverts commit 668a74e8.
10l, this change was unneeded, target_exec can be used to achive the same.

This is not a real error and memsetting always even when the
size did not change is overkill, but it still should be
an acceptable trade-off.

At the very least this should fix warnings about unused static
functions if one or more of these is not defined.
However even compilation might be broken if the compiler does
not optimize the function away completely.
This actually happens in case of the AVX function, since the
function pointer is used in an assignment that is not under
an #if and thus probably only optimized away after the function
was already marked as used.

Fixes several "‘static’ is not at beginning of declaration" warnings.

While we correctly "register" the side data when we split it,
the application (in this case FFmpeg) might not update the
AVPacket pool it uses to finally free the packet, thus
causing a leak.
This also makes the av_dup_packet unnecessary which could
cause an even worse leak in this situation.
Also change the code to not modify the user-provide AVPacket at all.
