[PATCH] Expose object ID computation functions.
This patch makes the first half of write_sha1_file() and
index_fd() externally visible, to allow callers to compute the
object ID without actually storing it in the object database.
[JC demangled the whitespaces himself because he liked the patch
so much, and reworked the interface to index_fd() slightly,
taking suggestion from Linus and of his own.]
