t/v2mirror.t and t/lei-mirror.t are now skipped when curl
is missing (instead of failing in appropriate places).
A bunch of which() checks are updated to use require_cmd
to avoid explicitly loading Spawn.

File::Temp only requires four 'X' characters (unlike mkstemp(3),
which requires six). So only so only give it 4 to avoid an
80-column violation and maybe save metadata space on FSes.

Using "make update-copyrights" after setting GNULIB_PATH in my
config.mak

fileno(DIRHANDLE) only works on Perl 5.22+, so we need to use
dirfd(3) ourselves from Inline::C (or rely on chattr(1) being
installed).
While we're at it, rename `set_nodatacow' to `nodatacow_fd'
for consistency with `nodatacow_dir'.

SQLite and Xapian files are written randomly, thus they become
fragmented under btrfs with copy-on-write. This leads to
noticeable performance problems (and probably ENOSPC) as these
files get big.
lore/git (v2, <1GB) indexes around 20% faster with this on an
ancient SSD. lore/lkml seems to be taking forever and I'll
probably cancel it to save wear on my SSD.
Unfortunately, disabling CoW also means disabling checksumming
(and compression), so we'll be careful to only set the No_COW
attribute on regeneratable data. We want to keep CoW (and
checksums+compression) on git storage because current ref
storage is neither checksummed nor compressed, and git streams
pack output.
