For 'nclx', the latest edition of the standard switched from JPEG XR
to 23001-8, which matches the current order of our entries. Bounds
are preserved as a sanity check.
For 'nclc', qtff edition 2016-09-13 introduced a few new entries.

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 f1b3e13138.
For some reason, gcc builds didn't crash, but clang builds do.

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 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.
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

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.
