fa3a382aa4 Handle ENOSPC errors better by preallocating the space before writing 
Prevent the case that we run out of space in the middle of
writing a block - that would leave a corrupt block behind.

3e367b29b0 config: Introduce ext4-style feature flags 
// List of feature flags this filesystem has enabled.
// If gocryptfs encounters a feature flag it does not support, it will refuse
// mounting. This mechanism is analogous to the ext4 feature flags that are
// stored in the superblock.

3f490d4d86 Bake version string into binary, add "--version" switch 
Example:

	./gocryptfs -version
	gocryptfs v0.2-20-gabcef9e-dirty; on-disk format 1

Note that you MUST compile using "./build.bash" for this to work.

af923d2d16 Automatically lazy-unmount when we get SIGINT or SIGTERM 
This hides the dangling "Transport endpoint is not connected"
mountpoint for everyone but processes that have file open inside
the mountpoint.

902babdf22 Refactor ciphertext <-> plaintext offset translation functions 
Move all the intelligence into the new file address_translation.go.
That the calculations were spread out too much became apparent when adding
the file header. This should make the code much easier to modify in the
future.

76311b60f2 Add file header (on-disk-format change) 
Format: [ "Version" uint16 big endian ] [ "Id" 16 random bytes ]

Quoting SECURITY.md:

* Every file has a header that contains a 16-byte random *file id*
* Each block uses the file id and its block number as GCM *authentication data*
 * This means the position of the blocks is protected as well. The blocks
   can not be reordered or copied between different files without
   causing an decryption error.
