av_dump_format needs the codecs opened in order to print
them.

av_init_packet does not reset data and size fields in AVPacket,
avcodec_encode_audio2 can use preallocated AVPacket.

Prevents all kind of badness if files contain multiple
indexes.

SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid
values larger than this in get_vlc2() (max_bits). tokens[][] can be
used as an index in deltas[], which has a size of 64, so ensure the
values are smaller than that.

This prevents crashes on corrupt bitstreams.

This one is available both in SDL 1.2 and in 1.3 (which is the current
version available e.g. in macports), while 1.3 doesn't contain
SDL_Linked_Version().

The current check for SDL_Linked_Version() (available since SDL 1.2.13)
was added in 8f1b06c8, because including the headers for SDL_Init()
redirects the main() function, requiring the main function signature
to match the one of SDL_main (including argc/argv).

Looks like some LAME versions produce dual stereo mode MP3s with
flags for intensity and middle stereo set. In this mode those flags
should be ignored like the reference decoder and derived ones do.

A call to decode_packet() does not always decode a complete WMA packet.
Moreover, this is not the correct place to document calls that are part
of the public API.

Also use correct buffer sizes in calls to tm2_read_stream(). Together,
this prevents overreads.

This allows falling back to a binary search if the file contains no
index, thus fixing seeking in such files (e.g. luckynight.wma).

dvdec.c uses nothing from dv_tablegen.h.  As a welcome side-effect, this
fixes compilation of that file with hardcoded tables enabled.

The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail.  Adding a slash fixes this and still works with make
3.81.

Also remove one pointless zero initialization in rangecoder.c.

It is not a user-accessible option and unlikely to ever be changed.

Otherwise realloc would free it, which would result in double free
later.

Tested to be bit-exact across x86-64, x86-32 and ppc.

We need to parse the individual packet durations when there is more than one
packet in a page.

Version from vqa header does not dictate which sound chunks may
appear in file.

Now that a documentation generator is built in the doc directory,
this is no longer necessary.  Fixes the Make warning:
Makefile:188: target `doc' given more than once in the same rule.
