Patch adds required helper functions to shaderapi.h and
the actual implementation.
Name generation copied from '_mesa_get_uniform_name' which can
be removed later by refactoring functions to use resource list.
The added functionality can be tested by tests for following
functions that are refactored by later patches:
GetActiveUniformName
GetActiveUniformBlockName
v2: no index for geometry shader inputs (Ilia Mirkin)
add bufSize < 0 check and error out
validate enum
corresponding Piglit test:
arb_program_interface_query-getprogramresourcename
