296bdf3af2 CipherSizeToPlainSize: Handle illegal states 
A file never gets a cipherSize <= HEADER_LEN in normal operation.
However, this can happen if header write it interrupted or the
underlying filesystem does not support fallocate.

Noticed while trying to store a CIPHERDIR in another gocryptfs mount
(gocryptfs does not support fallocate)

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

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.
