[RFC v3 0/4] string: Add equality APIs

[Alejandro Colomar]

Hi!

Here's v3 of this patch set (still RFC).

I still need to add tests.  BTW, I find the existing tests for the
*cmp() APIs quite unreadable.  I'd appreciate some help, as I don't know
where to start.

I also need to check how to properly format commit messages, and check
change logs.

The changes in this v3 are:

-  Add documentation in the manual.  I don't know how to check that the
   documentation formats properly, though; I'm not used to texi
   documentation.

-  Use bool/_Bool always.  This adds a requirement that the user needs
   a compiler that provides this type.  In GCC, this means 3.0 at least
   (at least, that's what was mentioned on libc-alpha@).

See the range-diff below.


Have a lovely day!
Alex
