Subject: odb: get rid of `the_repository` in `find_odb()`
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=de15f75ebfdfd110348e13a5112d7480fc51cee2;p=thirdparty%2Fgit.git

odb: get rid of `the_repository` in `find_odb()`

Get rid of our dependency on `the_repository` in `find_odb()` by passing
in the object database in which we want to search for the source and
adjusting all callers.

Rename the function to `odb_find_source()`.
