There is no need to cast the pointers passed to the penultimate
argument of the CryptDecodeObjectEx and CryptEncodeObjectEx functions
as those expect void pointers.

This prevents fallout from the GL_EXT_fog_coord emulation. glEnable
and glDisable calls other than those that change GL_FOG are not
hooked. The glEnableWINE and glDisableWINE functions can be used to
add other hooks too if ever needed.

The fog doesn't depend on pixel shaders any longer(but still vice
versa), so we don't need this state any more.

This is the "replacement" for the fog coord optimization removed in
the previous patch.

Current implementation uses only peek buffer if there is any data,
which causes reads one byte per call in common
InternetQueryDataAvailable/InternetReadFile scenario.

Fix also 192 printf format warnings produced by this change.
