Changing the C source to use fixnum instead of int.

[Aidan Kehoe]

Hi,

I’ve written the below script which, when run, makes changes that give an
18k-line diff. It changes the nomenclature in the C sources such that
fixnums are called fixnums and integers (that is, fixnums union bignums) are
called integers, and such that EMACS_INT_{MAX,MIN} have better names. It’s
pretty invasive, but the source is far more internally consistent after this
change. Further changes in this direction can’t really be done mechanically;
in particular the internals manual talks about integers and fixnums
interchangeably, and some comments in src/ do the same thing.

Comments? Objections?

Best,

Aidan
