These help avoiding overflows and simplify error handling.

It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

This field is private and should not be present in a public struct. It
is only used in DXVA with mpegvideo-based decoders currently.

This supports HMAC-MD5 and HMAC-SHA1 for now, other hashes are
simple to add.

In addition to the recent tables mess, the AVOption defaults behavior
changed, so an old lavc used with a new lavu will get completely messed
up defaults.

It is only used in that library.

Make av_pix_fmt_descriptors table static on next major bump.
Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.

The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.
If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).

Right now the buffer is zeroed, which does not represent silence for U8(P).

This adds a function to retrieve the number of entries in a
dictionary and updates the places directly accessing what should
be an opaque struct to use this new function instead.

Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

Both function ease allocating large arrays implementing the overflow
check inside it.
