This abstracts away the size of the hash values when copying them
from memory location to memory location, much as the introduction
of hashcmp abstracted away hash value comparsion.
A few call sites were using char* rather than unsigned char* so
I added the cast rather than open hashcpy to be void*. This is a
reasonable tradeoff as most call sites already use unsigned char*
and the existing hashcmp is also declared to be unsigned char*.
[jc: Splitted the patch to "master" part, to be followed by a
patch for merge-recursive.c which is not in "master" yet.
Fixed the cast in the latter hunk to combine-diff.c which was
wrong in the original.
Also converted ones left-over in combine-diff.c, diff-lib.c and
upload-pack.c ]

I often find myself typing this but the common abbreviation "g" for
"again" has not been supported so far for some unknown reason.

Introduces global inline:
hashcmp(const unsigned char *sha1, const unsigned char *sha2)
Uses memcmp for comparison and returns the result based on the length of
the hash name (a future runtime decision).

[jc: I needed to hand merge the changes to the updated codebase,
so the result needs to be checked.]

Most of the callers except the one in refs.c use the function to
update the index file. Among the index writers, everybody
except write-tree dies if they cannot open it for writing.
This gives the function an extra argument, to tell it to die
when it cannot create a new file as the lockfile.
The only caller that does not have to die is write-tree, because
updating the index for the cache-tree part is optional and not
being able to do so does not affect the correctness. I think we
do not have to be so careful and make the failure into die() the
same way as other callers, but that would be a different patch.

This changes the calling convention of built-in commands and
passes the "prefix" (i.e. pathname of $PWD relative to the
project root level) down to them.

hold_lock_file_for_update() relies on that.
