libavcodec/x86/videodsp.asm:128: warning: signed dword value exceeds bounds

x29 (FP) is a callee saved register and should be restored on
return. Instead of backing up x29 and restoring it here, back up
sp in a register that we are allowed to overwrite.

This fixes crashes in checkasm on aarch64 since f1b3e131.
For some reason, gcc builds didn't crash, but clang builds do.

The variable needs to be reset for each subdirectory.

Only works if packed headers are supported, where we can know the
output before generating the first frame.

The include was changed correctly in 4abe3b04
but then mistakenly changed back by c359d624
(it's not just the NAL unit types which are used).

This fixes many warnings of the sort
warning: label alone on a line without a colon might be in error

They only contain one line and will never contain more.

And move the asm recipe to the top-level Makefile next to the other
local pattern rules for .o files.

This, combined with clobbering the stack space prior to the call,
increases the chances of finding cases where 32 bit parameters
are erroneously treated as 64 bit.

Even if MAX_ARGS - 2 (for arm) or MAX_ARGS - 7 (for aarch64) parameters
are passed on the stack to checkasm_checked_call, we actually only
need to store MAX_ARGS - 4 (for arm) or MAX_ARGS - 8 (for aarch64)
parameters on the stack when calling the tested function.

This also fixes a minor bug introduced in the codecpar conversion, where
the termination condition for extracting the extradata does not match
the actual extradata setting code. As a result, the packet durations
made up by lavf go back to their values before the codecpar conversion.
That is of little consequence since that code should eventually be
dropped completely.

This is intended as a replacement for the 'split' function exported by
some parsers.

This code is independent from the decoder, so it makes more sense for it
to to have its own header.

This will be useful in the following commits.

This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.

This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

The spec says

9: Interlaced with bottom field displayed first and top field stored first
14: Interlaced with top field displayed first and bottom field stored first

And avcodec.h states

AV_FIELD_TB,          //< Top coded first, bottom displayed first
AV_FIELD_BT,          //< Bottom coded first, top displayed first

This is consistent with what file_open() does.

According to the public RTMP specification, these 4 bytes should
be zero.

librtmp in server mode assumes that the RTMPE (FP9) handshake is
used if these bytes are nonzero.

When acting as server, the server can include a "clientid" property
in some status messages. But this should be a unique number
identifying the client session, not identifying the server itself.
In practice, omitting it works just as well as including this
incorrect field.

This makes sure that e.g. Adobe FME actually reacts to it. As long
as the value we've been sending is the default one (128), the bug
hasn't been noticed.

Some applications such as Adobe FME append lots of parameters
here, making it easily overflow the current limit.

If this failed, we used to continue with an uninitialized
