Will simplify future changes (introducing proper
locking around opening/closing parsers).

It would be called while registering the codec, which means
it needlessly wastes memory when it is never used.
Instead do the work when first opening the codec.

The test for rweflags was dropped in a previous commit.

Move utilities description to a dedicated manual, consistent with what I
did with the rest of the documentation.

Some combinations of OS, VirtualDub, and VBLE can accidentally
set the version to a value other than 1. Since no other version
of VBLE was ever released, simply warn about it.

Since the resampler handles buffering of unconsumed samples internally, the
caller does not need this information.

It will always be the number of samples in the input buffer, so just use that
directly instead of passing it as a separate parameter.

This makes sure minimal configurations such as
"--disable-everything --enable-avconv" will enable the filters
necessary for running avconv, instead of just keeping avconv
disabled (even if the user specified "--enable-avconv").

This does not seem to have an effect currently. Fate-h264 passes with
THREADS=1..16 and both threading types as before. It fixes however a
segfault during error resilience with my adaptive-frame-mt patchset.
A picture in use during error resilience gets realloced in another
thread in the fuzzed sample sample_varPAR.avi_s226019.
