dowild() does case insensitive matching by lower-casing the text. That
means lower case letters in patterns imply case-insensitive matching,
but upper case means exact matching.
We do not want that subtlety. Lower case pattern too so iwildmatch()
always does what we expect it to do.

This makes wildmatch.c part of libgit.a and builds test-wildmatch; the
dependency on libpopt in the original has been replaced with the use
of our parse-options. Global variables in test-wildmatch are marked
static to avoid sparse warnings.
