...
dirfd caching was temporarily removed when moving
to the v2api. Add it back to gain back some lost speed.

dircache: increase cache size & lifetime
...
Looking at the dircache debug output, we see
that a "git status" workload has a very bad
cache hit rate because the entries expire or
get evicted before they can be reused.
Increase both cache size and lifetime for
a 4x speedup:
Before: 75s
After: 17s

main: Run 'ensure fds' code early during the program startup.
...
The files are apparently processed in alphabetic order, so cli_args.go is
processed before main.go. In order to run before the go-fuse imports, put
the 'ensure fds' code in a separate package. Debug messages are omitted
to avoid additional imports (that might contain other code messing up our
file descriptors).

tests: bump maxCacheFds to 3
...
As the dirCache now has 3 entries, the tests should accept
up to 3 extra fds without declaring an fd leak.

fusefrontend: fix fd leak in dirCache
...
The missing break meant that we may find a second
hit in the cache, Dup() a second fd, and leak the first
one.
Thanks @slackner for finding this.

fusefrontend: upgrade to three-entry dirCache

3 entries should work well for up to three parallel users.
It works well for extractloop.bash (two parallel tar extracts).
