Rename arguments in include/cmath to work around Newlib macro implementation using these particular names

[jroelofs]

Summary

This is a careful, mechanical renaming.

[jroelofs]

Here's one of many examples from Newlib's <math.h> that motivated this:

#define isgreater(x,y) (__extension__ ({__typeof__(x) __x = (x); __typeof__(y) __y = (y); !isunordered(__x,__y) && (__x > __y);}))

[EricWF]

I'll take a look at this tonight. If all it does is rename stuff It should be a very easy review.

[EricWF]

LGTM. I think we should change __z but I realize that if it doesn't cause any problems now it probably never will.

include/cmath

873–875

Take it or leave it but maybe we should change __e as well.

1213–1216

Lets do it for __z just to be consistent.

[jroelofs]

For consistency, I agree, I think s/__[ez]/_lcpp_\1/ is appropriate. Didn't see them before.

[jroelofs]

Also rename instances of e and z for consistency.
