a3c0f6784b Process LUKS keyslots in userspace through kernel crypto wrapper. 
This allow LUKS handling without requiring root privilege.

The dmcrypt device-mapper is used only for device activation now.

1436f2a0a0 Add wrapper for cipher block size query. 
There is no better way for now without loading crypto modules.

9563aa33c8 Fix PBKDF2 for crypto backens which does not support long HMAC keys. 
(Or it rehases key in every iteration.)

- Kernel backens seems not to support >20480 HMAC key
- NSS is slow (without proper key reset)

Add some test vectors (commented out by default).

1349efa34d Fix buildsytem to always include config.h. 
- config.h must always be the first file to be included
- Use AM_CFLAGS and AM_LDFLAGS consistently and properly.

(Modified to disable build without largefile support etc

7eccb7ff50 Change License for sub-libraries from GPLv2 only to LGPLv2.1+ ("or any later") 
This includes crypto, loopaes, tcrypt handling code I have written myself
and verity code written originally by Mikulas Patocka and modified by me,
copyright by Red Hat.

Other part of library have to stay GPLv2+ only for now
(no agreement from all authors).

23e144daf4 * Remove hash/hmac restart from crypto backend and make it part of hash/hmac final. 
Some backend implementation did reset context by default, so this
should create backend api consistent.

7b6eda0d27 Add skeleton and implementation of various crypto backends 
(gcrypt, OpenSSL, NSS and kernel crypto API supported for now).

There backends will be used for LUKS and plain passphrase hashing.

(Not yet used without following patches).
