This example should be useful to show the basic functionality of the
libswscale API.

More advanced features (scaling options etc., colorspace tweaking) may be
added later.

Eliminating finished streams avoids the progress stopping
with the first stream.
Using the max instead of the min avoids the progress stopping
with gaps in sparse streams (subtitles).
Negligible change for normal circumstances.

This script uses the flite source to produce files
suitable to test channels order and layout.

Extract of the output:

| Individual channels:
| NAME        DESCRIPTION
| FL          front left
| FR          front right
| <snip>
| SDR         surround direct right
|
| Standard channel layouts:
| NAME        DECOMPOSITION
| mono        FC
| stereo      FL+FR
| <snip>
| octagonal   FL+FR+FC+BL+BR+BC+SL+SR
| downmix     DL+DR

Instead, use it on the first member, since by definition, if
any member is aligned, the whole struct must be, in order to
maintain that alignment.

Fixes compilation with some finicky compilers, like a mix of libclang/msvc

Idea for fix from Måns Rullgård.

This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

Using the malloc variant avoids pointless memcpy on size
increase and simplifies handling allocation failure.
Also change code to ensure that allocation, bswap and bitstream
reader all use the same size, even when the packet size is odd
for example.

Add a switch which controls which operation to perform.  Useful to test
only a single feature. Also the new behavior is more self-consistent.

Use $(RM) in place of rm, drop useless "-r" for removing files.
