    Convert "bit" parameters to GLbitfield. Fix cut-and-paste bug in _mesa_IsEnabled
    
    These changes are based on patch review comments from Brian Paul, Alan
    Hourihane, and vehemens.

commit 87a980a795b29c5114c07a74aa5d95b6e7a7f971

    Refactor the loop in unbind_texobj_from_texunits.
    
    Common code was pulled out of the per-target if-statment and put at the end
    of the for-loop.  The common code is guarded by a new variable, curr, that
    is set to point to the unit's current target in each if-statement.

commit e282f89a380bfbc8ad4840b535b499541635ca9f

    Refactor queries of GL_(SOURCE|OPERAND)[012]_(ALPHA|RGB).
    
    Most switch-statements that have cases for these enums already use code like:
    
        const GLuint idx = pname - GL_SOURCE0_RGB;
        ... texUnit->Combine.SourceRGB[idx] ...
    
    This patch just brings the remaining bits up to speed.
