d56f1ee179 stress_tests: extractloop: run two loops in parallel 
This increases the load but also the disk space requirements
(to about 2GB).

730291feab fusefrontend: fix wlock memory leak 
The write lock was not freed on release, causing a slow memory leak.

This was noticed by running extractloop.bash for 10 hours.

e97962bd3f stress_tests: add stress test scripts 
These were hosted at https://github.com/rfjakob/fsstress . To
make them easier to use for gocryptfs users and developers, add
them to the main repo.

cf29ce3762 stupidgcm: set dummy locking callback. 
In general, OpenSSL is only threadsafe if you provide a locking function
through CRYPTO_set_locking_callback. However, the GCM operations that
stupidgcm uses never call that function.

To guard against that ever changing, set a dummy locking callback
that crashes the app.

906172938a stupidgcm: skip tests on Go 1.4 and older 
Quoting from the patch:

	We compare against Go's built-in GCM implementation. Since stupidgcm only
	supports 128-bit IVs and Go only supports that from 1.5 onward, we cannot
	run these tests on older Go versions.

b4d45554f2 Revert "stupidgcm: print openssl error stack before panicing" 
This did not help in debugging the openssl <= 1.0.1c issue at all
and makes the code more complex. Keep it simple.

508a949d9d stupidgcm: reorder calls to support openssl <= 1.0.1c 
This fixes the test failures on Travis CI.

Quoting from 07a4ff79d2

	/* Set expected tag value. A restriction in OpenSSL 1.0.1c and earlier
	 * required the tag before any AAD or ciphertext */

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 )
