reserved identifier violation

I would like to point out that identifiers like “[`__DRI_BUFFER_FRONT_LEFT`](https://github.com/intel/libva/blob/b3be72a5a110880f70626d7c3bed953cdde124b2/va/x11/dri2_util.c#L40 "Update candidate")” and “[`_VA_BACKEND_H_`](https://github.com/intel/libva/blob/b3be72a5a110880f70626d7c3bed953cdde124b2/va/va_backend.h#L29 "Another update candidate")” [do eventually not fit](https://www.securecoding.cert.org/confluence/display/c/DCL37-C.+Do+not+declare+or+define+a+reserved+identifier "Do not use identifiers which are reserved for the compiler implementation.") to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?
