wip/gnurl: Update to 7.65.1
Changelog:
CHANGELOG
---------
Changes, gnurl specific:
* (docs) merged documentation changes from curl
* (tests/build) previously, unknown to me, having valgrind in your path
and running the tests would lead under certain system configurations
to tests coredumping all over the place. The new switch 'disable-valgrind'
takes care of running the tests cleanly (by invoking runtests.pl with -n
even if this condition applies.
The usual curl Changelog applies, consult https://curl.haxx.se for the
ChangeLog.
