92dad6687f arm: fix use of uninitialised value in ff_fft_fixed_init_arm() 
When initialising an FFTContext for a plain FFT, mdct_bits is not set
and can contain a garbage value.  Since nbits is always valid and for
MDCT operation is mdct_bits - 2 checking this instead avoids using an
uninitialised value while having the same effect.

2c96392277 avpicture: Don't assume a valid pix fmt in avpicture_get_size 
When called from the v4l2 input device, pix_fmt can be
AV_PIX_FMT_NONE (for jpeg formats). Before 50ba57e0, this wasn't
an issue for avpicture_get_size, but after that commit, this
lead to crashes.

2aef3d66c9 SBR DSP x86: implement SSE sbr_hf_gen 
Start and end index are multiple of 2, therefore guaranteeing aligned access.
Also, this allows to generate 4 floats per loop, keeping the alignment all
along.

Timing:
- 32 bits: 326c -> 172c
- 64 bits: 323c -> 156c

da025d115a fate: workaround for slighly broken 'test' shell builtin 
Some shells, e.g. minix3, have a broken 'test' builtin which fails
if the first operand of a binary operator looks like a unary operator.
Prefixing the values with 'x' prevents this from happening.

eb7018d2fc configure: Strip ordinals from mingw generated def files 
The def files are used for generating import libraries for
other toolchains (in particular, for generating import libraries
for MSVC for DLLs built with mingw).

The def files produced by mingw/gcc contains ordinals for each
exported function. When MSVC tools generate import libraries
from such a def file, MSVC links to the DLL by the ordinals
instead of linking by name.

Since the def files aren't maintained by hand, the ordinal
numbers are assigned (more or less) randomly and any caller
linking to the libs by ordinals will break as soon as the libraries
export more/fewer functions.

Therefore, strip out the ordinals from the generated def files,
to make users link to the libraries by name.

Callers linking to the DLLs using the gcc provided import library
link by name as they should.
