Re: [PATCH 1/2] compat: move unaligned helpers to bswap.h

Commit d60c49c (read-cache.c: allow unaligned mapping of the
index file, 2012-04-03) introduced helpers to access
unaligned data. Let's factor them out to make them more
widely available.

While we're at it, we'll give the helpers more readable
names, add a helper for the "ntohll" form, and add the
appropriate Makefile knob.

Weird.  Why wasn't git broken on the relevant platforms before (given
that no one has been setting NEEDS_ALIGNED_ACCESS for them)?

Puzzled,
