The record_person function just parses out the "name" field
of the person line in a commit and adds it to a string_list.
The only reason we need an extra buffer is that the
string_list functions require a NUL-terminated string.
Instead of the static buffer, we can just allocate a
temporary NUL-terminated copy. In addition to removing a
useless limit, this removes the only user of MAX_GITNAME
outside of ident.c.

This actually introduces an extra malloc() per commit that we analyze. I
doubt we care, but if we do, the right solution IMHO is to introduce
string-list functions which can lookup or add a (buf, len) pair and
avoid the copy altogether.
