git-svn has several variables for SHA-1 constants, including short hash
values and full length hash values. Since these are no longer SHA-1
specific, let's start them with "oid" instead of "sha1". Add a
constant, oid_length, which is the length of the hash algorithm in use
in hex. We use the hex version because overwhelmingly that's what's
used by git-svn.
We don't currently set oid_length based on the repository algorithm, but
we will in a future commit.
