Many places throughout the code use "unsigned char [20]" to store object IDs
(SHA-1 values). This leads to lots of hardcoded numbers throughout the
codebase. It also leads to confusion about the purposes of a buffer.
Introduce a structure for object IDs. This allows us to obtain the benefits
of compile-time checking for misuse. The structure is expected to remain
the same size and have the same alignment requirements on all known
platforms, compared to the array of unsigned char, although this is not
required for correctness.

There are several utility functions (hashcmp and friends) that are used
for comparing object IDs (SHA-1 values). Using these functions, which
take pointers to unsigned char, with struct object_id requires tiresome
access to the sha1 member, which bloats code and violates the desired
encapsulation. Provide wrappers around these functions for struct
object_id for neater, more maintainable code. Use the new constants to
avoid the hard-coded 20s and 40s throughout the original functions.
These functions simply call the underlying pointer-to-unsigned-char
versions to ensure that any performance improvements will be passed
through to the new functions.

Convert struct commit_graft and necessary local parts of commit.c.
Also, convert several constants based on the hex length of an SHA-1 to
use GIT_SHA1_HEXSZ, and move several magic constants into variables for
readability.
