1caa925868 Increase GCM IV size from 96 to 128 bits 
This pushes back the birthday bound for collisions to make it virtually
irrelevant.

88826dc51d diriv: handle directory rename over directory 
If an empty directory is overwritten we will always get
ENOTEMPTY as the "empty" directory will still contain gocryptfs.diriv.
Handle that case by removing the target directory and trying again.

Fixes issue #10

8518d6d7bd Handle EINTR returned by Fallocate 
Fallocate can return EINTR (interrupted system call) and does so
quite often when cpu profiling is enabled.

ccf6d00728 Add missing PlaintextNames checks in OpenDir, Mkdir, Rmdir, initDir 
Plaintextnames support has bitrotted during the DirIV additions,
this needs test cases. Will be added in a future patch.

gocryptfs is no longer developed in gocryptfs because of the inconvenience
that you cannot mount a FUSE filesystem inside a FUSE mount

56888d83dd fallocate the space needed for the file header beforehand 
This makes sure writing to a file fails early if the underlying
filesystem does not support fallocate. It also prevents partial header
write due to ENOSPC.

71b94828ed init: create gocryptfs.diriv after creating gocryptfs.conf 
Creating the config file can fail easily, for example if the
password is not entered the same twice. This would leave an
orphaned gocryptfs.diriv behind.
