d3764b7753 reverse: fix longname decoding bug
This could have caused spurious ENOENT errors.

That it did not cause these errors all the time is interesting
and probably because an earlier readdir would place the entry
in the cache. This masks the bug.

75ebb28a62 ctlsock: add initial limited implementation
At the moment, in forward mode you can only encrypt paths
and in reverse mode you can only decrypt paths.

b527e205e2 main: rename "-f" to "-fg"
"-f" looks too much like "--force". The old variant is still

Also, use "%#v" instead of JSON for debug output.
This means we can unexport all fields.

944eaf2fb5 fusefronted: expire dir IV cache after one second
The Back In Time backup tool (https://github.com/bit-team/backintime)
wants to write directly into the ciphertext dir.
This may cause the cached directory IV to become out-of-date.
Having an expiry time limits the inconstency to one second, like
attr_timeout does for the kernel getattr cache.

012152f3d1 fusefrontend: I/O error instead of panic on all-zero nonce
Running xfstests generic/075 on tmpfs often triggered a panic
for what seems to be a tmpfs bug.

Quoting from the email to lkml,
http://www.spinics.net/lists/kernel/msg2370127.html :

	tmpfs seems to be incorrectly returning 0-bytes when reading from
	a file that is concurrently being truncated.

4cc64c2c95 main: redirect panics to /tmp/gocryptfs_panic.NNNN
Redirect stdout and stderr to /tmp/gocryptfs_paniclog.NNNNNN
instead of closing them so users have a chance to get the
backtrace on a panic.

This only applies if "-nosyslog" is NOT set. Panics will
go to terminal as usual if it is.

a08d55f42d fusefronted: optimize NFS streaming writes by saving one Stat()
Stat() calls are expensive on NFS as they need a full network
round-trip. We detect when a write immediately follows the
last one and skip the Stat in this case because the write
cannot create a file hole.

On my (slow) NAS, this takes the write speed from 24MB/s to
41MB/s.
