Convert several static functions to take pointers to struct object_id.
Change the relevant parameters to write_packed_entry to be const, as we
don't modify them. Rename lock_ref_sha1_basic to lock_ref_oid_basic to
reflect its new argument. Update the docstring for verify lock to
account for the new parameter name, and note additionally that the
old_oid may be NULL.

Convert the unsigned char * parameter to struct object_id * for
files_read_raw_ref and packed_read_raw_ref. Update the documentation.
Switch from using get_sha1_hex and a hard-coded 40 to using
parse_oid_hex.

Convert these two functions and the functions that underlie them to take
pointers to struct object_id. This is a prerequisite to convert
resolve_gitlink_ref. Fix a stray tab in the middle of the index_mem
call in index_pipe by converting it to a space.

reflog_expire already used struct object_id internally, but it did not
take it as a parameter. Adjust the parameter (and the callers) to pass
a pointer to struct object_id instead of a pointer to unsigned char.
Remove the temporary inserted earlier as it is no longer required.

All of the callers of these functions just pass the hash member of a
struct object_id, so convert them to use a pointer to struct object_id
directly. Insert a check for NULL in expand_ref on a temporary basis;
this check can be removed when resolve_ref_unsafe is converted as well.

Several of the refs functions take NULL to indicate that the ref is not
to be updated. If refs_update_ref were called with a NULL new object
ID, we could pass that NULL pointer to write_pseudoref, which would then
segfault when it dereferenced it. Instead, simply return successfully,
since if we don't want to update the pseudoref, there's nothing to do.

The write_entry() function switches on the mode of the entry
we're going to write out. The cases for S_IFLNK and S_IFREG
are lumped together. In earlier versions of the code, this
made some sense. They have a shared preamble (which reads
the blob content), a short type-specific body, and a shared
conclusion (which writes out the file contents; always for
S_IFREG and only sometimes for S_IFLNK).
But over time this has grown to make less sense. The preamble
now has conditional bits for each type, and the S_IFREG body
has grown a lot more complicated. It's hard to follow the
logic of which code is running for which mode.
Let's give each mode its own case arm. We will still share
the conclusion code, which means we now jump to it with a
goto. Ideally we'd pull that shared code into its own
function, but it touches so much internal state in the
write_entry() function that the end result is actually
harder to follow than the goto.
While we're here, we'll touch up a few bits of whitespace to
make the beginning and endings of the cases easier to read.

When retrying a delayed filter-process request, we don't
need to send the blob to the filter a second time. However,
we read it unconditionally into a buffer, only to later
throw away that buffer. We can make this more efficient by
skipping the read in the first place when it isn't
necessary.

When write_entry() retries a delayed filter request, we
don't need to send the blob content to the filter again, and
set the pointer to NULL. But doing so means we leak the
contents we read earlier from read_blob_entry(). Let's make
sure to free it before dropping the pointer.

A common mistake when writing binary search is to allow possible
integer overflow by using the simple average:
mid = (min + max) / 2;
Instead, use the overflow-safe version:
mid = min + (max - min) / 2;
This translation is safe since the operation occurs inside a loop
conditioned on "min < max". The included changes were found using
the following git grep:
git grep '/ *2;' '*.c'
Making this cleanup will prevent future review friction when a new
binary search is contructed based on existing code.
