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.

This patch allows the user to force flushing of all queued packets
by calling av_interleaved_write_frame() with pkt set to NULL.

Also remove some write-only variables or write-only variable
assignments, remove internal colorspace conversion to native
endianness (that can be done by swscale much more efficiently),
and some cosmetics.

Prevents running error resilience on a previous frame which will write
to the pic->mb_type[] array of the previous image. The array might
already be re-used for a new image in a subsequent thread, thus cause
two threads to write to the same pic->mb_type[] array, causing a race
condition which can crash in rv34_decode_cbp(), called by
rv34_decode_inter_mb_header() (which accesses mb_type[] twice,
assuming values are maintained, which the race condition breaks).

This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

Remove confusing sentence that implied the user should set the timebase.
Elaborate on how the timebase is set for muxing.
