The new name is more consistent with the codebase, and more
self-consistent with the libswscale API.

Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.

This fixes two problems:
 - the invalid pad.name stack pointer after init() ends
 - the duplicated name for all inputs

Generate quantization tables when they are not present in the
first chunk.

They belong in the init functions specific to each CPU capability.

They have been wrong since 11d957fbd8

New streams may be created at any time, e.g. on codec change.

Allow to specify options affecting the segment list generation.

In particular: add +live and +cache flags.

For a full discussion read trac ticket #1642:

Also add live M3U8 generation example.

Allow to skip section name at the begin of each line. Possibly simplify
output.

Factorize writer class definition.

The 64 bit cl.exe version 16.00.30319.01 crashes with an internal
compiler error on the current check (and thus deduces it isn't
supported, even if the actual usage in libavuil/x86/cpu.c works
fine), but by assigning the value from the intrinsic to a variable,
or returning it, it works fine.

This error is fixed in cl.exe version 16.00.40219.01.

Some msvcrt versions (the static 64 bit libc in MSVC 10) have
a log2 function, but there is no declaration for it in the headers.
Therefore, the normal configure check might find it, but it can fail
during build or at runtime, depending on whether implicit function
declarations are an error or not.

Therefore simply ignore this function on this platform.
