Merge branch 'lt/block-sha1'

* lt/block-sha1:
  block-sha1/sha1.c: silence compiler complaints by casting void * to char *
  block-sha1: more good unaligned memory access candidates
  block-sha1: support for architectures with memory alignment restrictions
  block-sha1: split the different "hacks" to be individually selected
  block-sha1: move code around
  block-sha1: improve code on large-register-set machines
  block-sha1: improved SHA1 hashing
  block-sha1: perform register rotation using cpp
  block-sha1: get rid of redundant 'lenW' context
  block-sha1: Use '(B&C)+(D&(B^C))' instead of '(B&C)|(D&(B|C))' in round 3
  block-sha1: macroize the rounds a bit further
  block-sha1: re-use the temporary array as we calculate the SHA1
  block-sha1: make the 'ntohl()' part of the first SHA1 loop
  block-sha1: minor fixups
  block-sha1: try to use rol/ror appropriately
  block-sha1: undo ctx->size change
  Add new optimized C 'block-sha1' routines
