f9158b01d0 swresample/resample: Limit filter length 
Related to CID1197063

The limit choosen is arbitrary and much larger than what makes sense.
It avoids the need for checking arithmetic operations with the length for overflow

7c8bf09edd swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2 
pshuf+paddd is slightly faster than phaddd.
The real gain is in pre-ssse3 processors like AMD K8 and K10, which get
a big boost in performance compared to the mmxext version

cbeaf67888 Avoid using empty macro arguments. 
These are not supported by all compilers (gcc 2.95 but also older SPARC
compilers, see gcc bug #33304 for example), and there is no real need for them.
One use of this feature remains in libavdevice/v4l2.c which can't be
replaced quite as easily.

334e2e2363 lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value 
The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.

INT_MAX is used here to denote the max allowed value for a sample format.

The opt-test code is changed to provide a valid reference example.

56572787ae Add Windows resource file support for shared libraries 
Originally written by James Almer <jamrial@gmail.com>

With the following contributions by Timothy Gu <timothygu99@gmail.com>

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.
