[PATCH] inet_pton.c: use locale-independent tolower

[Jim Meyering]

Hi Simon,

I'd like to make this change, so that inet_pton's parsing is
locale-independent.  No real risk of problem, but this change does get me
past a failure of a relatively strict "make syntax-check" test in libvirt.
And besides, we certainly don't need locale-related conversions to map
A-F to a-f.

Ok to commit?

* lib/inet_pton.c: Include <c-ctype.h> rather than <ctype.h>.
(inet_pton6): Use c_tolower rather than tolower.
* modules/inet_pton (Depends-on): Add c-ctype.
