Introduce a new generic `odb_find_abbrev_len()` function as well as
source-specific callback functions. This makes the logic to compute the
required prefix length to make a given object unique fully pluggable.

Same as the preceding commit, move the logic that computes the minimum
required prefix length to make a given object ID unique for the packfile
store into a new function `packfile_store_find_abbrev_len()` that is
part of "packfile.c". This prepares for making the logic fully generic
via pluggable object databases.

The function `repo_find_unique_abbrev_r()` takes as input an object ID
as well as a minimum object ID length and returns the minimum required
prefix to make the object ID unique.
The logic that computes the abbreviation length for loose objects is
deeply tied to the loose object storage format. As such, it would fail
in case a different object storage format was used.
Prepare for making this logic generic to the backend by moving the logic
into a new `odb_source_loose_find_abbrev_len()` function that is part of
"object-file.c".

The function `extend_abbrev_len()` computes the length of common hex
characters between two object IDs. This is done by:
- Making the caller provide the `hex` string for the needle object ID.
- Comparing every hex position of the haystack object ID with
`get_hex_char_from_oid()`.
Turning the binary representation into hex first is roundabout though:
we can simply compare the binary representation and give some special
attention to the final nibble.
Introduce a new function `oid_common_prefix_hexlen()` that does exactly
this and refactor the code to use the new function. This allows us to
drop the `struct min_abbrev_data::hex` field. Furthermore, this function
will be used in by some other callsites in subsequent commits.
