  lavc: fix misspelling in comment
  aac: propagate error return values for AV_LOG_ERROR-triggering events
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Previously both the buffer and buffersink elements were associated to
the "BUFFER" symbol in allfilters.c, so it was not possible to enable
one without the other.

void* pointer arithmetic semantics is undefined, use uint8_t* instead.

Also fix GCC warnings:
defaults.c: In function ‘set_common_formats’:
defaults.c:184: warning: pointer of type ‘void *’ used in arithmetic
defaults.c:189: warning: pointer of type ‘void *’ used in arithmetic

Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Also remove channel_layout check as it is now negotiated.

The function is not implemented (and possibly useless).

The logged information is possibly false, and it tends to be outdated
after each change since the logging code needs to be manually updated.

Simplify and prevent confusing wrong debug messages.

Also remove the unnecessary isSupportedIn/Out macros.

Make the code more compact/readable, and simplify the access to
lsws-specific pixel format information.

The v->ctx is always not NULL now, check for streams presence to
mark the read_header state.

Increase size of the private temporary buffers from w to FFMAX(w, h),
indeed they are used also for blurring vertical lines with length h.

Make more clear the meaning of the variables. They specify the length
of a (vertical or horizontal) line rather than a width.
Less confusing.
