Bug 1156: Utilize internal glGetStringi (same as glGetString) - Robostness
Using EGL-GBM, using desktop GL we end up with an unsatisfied linkage error after the ProcAddressTable
has been reset using the 'hasMajor' and 'hasCtxOptions'.
However looking up using 'reqMajor' and 'reqCtxOptions' seems to work.
Needs more analysis.
This change also increases robustness for scanning through GL profiles at initialization.
