	There are multiple sites in "object-file-convert.c" where we use the global `the_repository` variable, either explicitly or implicitly by using `the_hash_algo`. All of these callsites are transitively called from `convert_object_file()`, which indeed has no repo as input. Refactor the function so that it receives a repository as a parameter and pass it through to all internal functions to get rid of the dependency. Remove the `USE_THE_REPOSITORY_VARIABLE` define.

2023-10-02	object-file-convert: stubs for converting from one object format to another	Eric W. Biederman	1	-0/+24
	Two basic functions are provided: - convert_object_file Takes an object file it's type and hash algorithm and converts it into the equivalent object file that would have been generated with hash algorithm "to". For blob objects there is no conversation to be done and it is an error to use this function on them. For commit, tree, and tag objects embedded oids are replaced by the oids of the objects they refer to with those objects and their object ids reencoded in with the hash algorithm "to". Signatures are rearranged so that they remain valid after the object has been reencoded. - repo_oid_to_algop which takes an oid that refers to an object file and returns the oid of the equivalent object file generated with the target hash algorithm. The pair of files object-file-convert.c and object-file-convert.h are introduced to hold as much of this logic as possible to keep this conversion logic cleanly separated from everything else and in the hopes that someday the code will be clean enough git can support compiling out support for sha1 and the various conversion functions.
