for condition comparison and cleanup multiline comment style
In sha*_ctx_mgr_submit, we currently use the | operator instead of ||
((ctx->partial_block_buffer_length) | (len < SHA1_BLOCK_SIZE))
Switching it to || and remove extraneous paranthesis to
adhere to coding style.
Also cleanup inconsistent multiline comment style.

This patch introduces the assembly routines to do SHA256 computation
on buffers belonging to several jobs at once. The assembly routines
are optimized with AVX2 instructions that have 8 data lanes and using
AVX2 registers.

This patch introduces the data structures and prototypes of
functions needed for computing SHA256 hash using multi-buffer.
Included are the structures of the multi-buffer SHA256 job,
job scheduler in C and x86 assembly.

This patch introduces the routines used to submit and flush buffers
belonging to SHA256 crypto jobs to the SHA256 multibuffer algorithm. It
is implemented mostly in assembly optimized with AVX2 instructions.

This patch introduces the multi-buffer job manager which is responsible for
submitting scatter-gather buffers from several SHA256 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 SHA256 crypto job.
The SHA256 multi-buffer crypto algorithm is defined and initialized in
this patch.
