Merge remote-tracking branch 'qatar/master'

* qatar/master:
  fate: Allow setting the ld parameter from the config file
  x86: dsputil: Do not redundantly check for CPU caps before calling init funcs
  configure: Disable some warnings in MSVC
  x86: vp56: cmov version of vp56_rac_get_prob requires inline asm
  avopt: fix examples to match the same style about default values as the actual code.
  configure: Add support for MSVC cl.exe/link.exe
  lavu: add snprintf(), vsnprint() and strtod() replacements for MS runtime.

Conflicts:
	libavutil/opt.h
