Win,ARB,GL-2.x: Fix pfd to caps conversion: !pbuffer / Cleanup

This fix enables the configuration
    win7 64bit chromium2.1 (virtual box 4.0.2 linux host)

Querying unsupported pixel format attributes, ie pbuffer,
will fail the ARB attribute query functions.

Cleanup of SharedResource's, hold all reused flags in win32 impl,
ie pbuffer, arb pixelformat, ..
