These functions are modeled after the corresponding utilities in
libavutil/timestamp.h.

Introduce a new function to set binary data through AVOption,
avoiding having to convert the binary data to a string inbetween.

Move AVPALETTE_SIZE and AVPALETTE_COUNT definition from
libavcodec/avcodec.h to libavutil/pixfmt.h.

The definition is more useful in libavutil, where it can be shared for
example by libavfilter and libswscale.

This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

The functions operate on the sample level rather than the byte level and work
with all audio sample formats.

Also, use the new function in the AC-3 encoder.

Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

Theres no usefull or even remotely complete information on it currently.
Which just leads to confusion.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

Factorize code and provide ratio parsing consistency.

The functions are already av_ prefixed and intfloat header is already provided.
Install libavutil/intfloat.h

They allow to implement the if/then/else logic, which cannot be
implemented otherwise.

For example the expression:
A*B + not(A)*C

always evaluates to NaN if B is NaN, even in the case where A is 0.

Add it to doc/APIchanges and update and correct other entries.

This is the usual weirdness with const/non-const pointers through a function.
See the prototype of strchr for a standard example.

The function had to be moved down, below the point where stdint.h is
indirectly included.

It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.
