This patch introduces the multi-buffer job manager which is responsible
for submitting scatter-gather buffers from several SHA1 jobs to the
multi-buffer algorithm. It also contains the flush routine to that's
called by the crypto daemon to complete the job when no new jobs arrive
before the deadline of maximum latency of a SHA1 crypto job.
The SHA1 multi-buffer crypto algorithm is defined and initialized in
this patch.

This patch introduces the assembly routines to do SHA1 computation on
buffers belonging to serveral jobs at once. The assembly routines are
optimized with AVX2 instructions that have 8 data lanes and using AVX2
registers.

This patch introduces the routines used to submit and flush buffers
belonging to SHA1 crypto jobs to the SHA1 multibuffer algorithm. It is
implemented mostly in assembly optimized with AVX2 instructions.

This patch introduces the data structures and prototypes of functions
needed for computing SHA1 hash using multi-buffer. Included are the
structures of the multi-buffer SHA1 job, job scheduler in C and x86
assembly.
