Remove MSVC solution user state files that shouldn't be version controlled
Remove the 2010 and 2012 MSVC project files from WelsVP as well

The corresponding files for the decoder and encoder were
removed in ccca04453a3. The 2008 version can be imported into
MSVC 2010 and 2012 just fine, reducing the amount of project files
to keep in sync.
Remove the unused solution and project files for WelsVideoProcessor

These are for building source files that aren't present in the
project any longer.
Remove the MSVC solution for WelsVP

This isn't necessary, it can be built via the encoder solution.
Include the executable extension in the test rule dependency

This fixes "make test" on platforms that have an executable
extension.
Remove the unused dllname parameter to the trace function
Make a function typedef actually use the right type

All functions that are assigned to function pointers with this
typedef (WelsHadamardQuant2x2Skip_c and WelsHadamardQuant2x2Skip_mmx)
use int32_t instead of BOOL_T for the return value.
Remove an unnecessary cast when setting function pointers

By removing the casts we make sure that the function signature
actually matches and isn't silenced by the cast.
Make the function signatures actually match when used as function pointer

Hiding the function signature mismatch with a cast can lead to
more concrete breakage being missed.
Fix a typo, "vender" -> "vendor"
Do chdir within mktargets.py

This simplifies the calling shell script.
