1e00bbb10c avcodec/lcldec: Check that dimensions are a multiple of the subsample factors 
Other dimensions would not work correctly currently,
also ask for a sample for files that fail this check.

This fixes an integer overflow leading to out of array
accesses.

e41cd3cdeb aacenc: Fix ticket #1784: erasure of surround channels 
This was due to a miscomputation of s->cur_channel, which led to
psy-based encoders using the psy coefficients for the wrong channel.
Test sample attached on the bug tracker had the peculiar case of all
other channels being silent, so the error was far more noticeable.

e08c946c68 configure: Explicitly disable PIC when targeting win32/mingw 
These platforms do not have any notion of PIC. On some compilers,
enabling pic produces a number of warnings.

This avoids trying to produce PIC loads in the ARM assembly - there
are no relocation types in PE/COFF that correspond to
BFD_RELOC_32_PCREL (R_ARM_REL32 in ELF).

As a side-effect, this avoids enabling PIC on mingw64, getting rid
of the warnings about PIC not having any effect on that platform.

With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.
