crypto: xctr - Add XCTR support 

Add a generic implementation of XCTR mode as a template.  XCTR is a
blockcipher mode similar to CTR mode.  XCTR uses XORs and little-endian
addition rather than big-endian arithmetic which has two advantages:  It
is slightly faster on little-endian CPUs and it is less likely to be
implemented incorrect since integer overflows are not possible on
practical input sizes.  XCTR is used as a component to implement HCTR2.

More information on XCTR mode can be found in the HCTR2 paper:

XCTR: XOR Counter mode. This blockcipher mode is a variant of CTR mode

/*
* XCTR mode is a blockcipher mode of operation used to implement HCTR2. XCTR is
* closely related to the CTR mode of operation; the main difference is that CTR
* generates the keystream using E(CTR + IV) whereas XCTR generates the
* keystream using E(CTR ^ IV). This allows implementations to avoid dealing
* with multi-limb integers (as is required in CTR mode). XCTR is also specified
* using little-endian arithmetic which makes it slightly faster on LE machines.
*
* See the HCTR2 paper for more details:
* Length-preserving encryption with HCTR2
