nxstyle should not complain on _Exit

[yamt]

e.g.

% nxstyle stdlib.h
stdlib.h:152:19: error: Mixed case identifier found

Maybe nxstyle could be extended to recognize some special comment that instructs to ignore a line (or at least a given rule for that line)

This has been discussed and I, for one, have been very opposed to corrupting good, clean C files with meta-data for nxstyle. People have talked about a lot of things and we have done the best we can to squash that approach. It is an unbounded, open-ended can or worms.

for this specific case (_Exit), as it's a part of the standards, it's more appropriate to make nxstyle itself know, IMO.

There already is a white list in nxstyle.c, we can just add _Exit to the list.

diff --git a/tools/nxstyle.c b/tools/nxstyle.c

That actually is just a prefix list but we can do the same for full identifiers.
