[PATCH lt/block-sha1 0/2 v3] block-sha1: avoid pointer conversion that violates alignment constraints

[Jonathan Nieder <jrnieder@gmail.com>]

Hi Junio,

This is a series of two patches: the first avoids alignment faults
that were making git either slow on Alpha machines or crashy,
depending on the machine's configuration, and the second patch is a
cosmetic nit noticed while reviewing the first.

Patches are based against

  30ae47b4 remove ARM and Mozilla SHA1 implementations, 2009-08-17

(aka the tip of the lt/block-sha1 branch) for no particular reason.
They should work fine against a more modern codebase if you prefer
that.

No changes since v2[1] except to commit messages.

I think this should be ready for application.  Thanks to Michael and
Linus for shaping the original patch into something sane.

Thoughts?
Jonathan
