Fix compilation on OpenBSD
commit: don't include the LF in the header field value

When the encoding header changed to be treated as an additional
header, the EOL pointer started to point to the byte after the LF,
making the git__strndup call copy the LF into the value.

Increase the EOL pointer value after copying the data to keep the rest
of the semantics but avoid copying LF.
Parse commit time as uint64_t to avoid overflow

The commit time is already stored as a git_time_t, but we were
parsing is as a uint32_t.  This just switches the parser to use
uint64_t which will handle dates further in the future (and adds
some tests of those future dates).

Fix case sensitivity bug with tree iterators

With the new code to make tree iterators support ignore_case,
there is a bug in setting the start entry for range bounded
iterators where memcmp was being used instead of strncasecmp.
This fixes that and expands the tree iterator test to cover
the cases that were broken.
