c92190bf07 stupidgcm: add our own thin wrapper around openssl gcm 
...complete with tests and benchmark.

This will allow us to get rid of the dependency to spacemonkeygo/openssl
that causes problems on Arch Linux

4c9e249e3a Convert fdLock to an RWMutex and protect the whole transaction 
...against concurrent closes.

The testcase

	(set -e; while true; do truncate -s $RANDOM b; done) &
	(set -e; while true; do truncate -s $RANDOM b; done) &

uncovered lots of unnecessary RMW failures that were the result
of concurrent closes.

With this patch, the only remaining error is "Truncate on forgotten file"
that is probably caused by a problem in the go-fuse lib
( https://github.com/hanwen/go-fuse/issues/95 )

read the diriv is not an error in that case.

2f32114bd3 Add per-inode write mutex 
At the moment, FUSE writes to a single file are serialized by the kernel.
However, it is unclear if this is guaranteed behaviour or may change
in the future.

This patch adds our own per-inode write lock to rule out races regardless
of kernel behavoir.

d163169655 Wrap Logger to make disabling output more efficient 
Instead of using SetOutput(ioutil.Discard), which means
that Printf is still called for every debug message,
use a simple and fast boolean check.

Streaming write performance improves from 86 to 93 MB/s.
