[v2,02/21] environment: make `get_git_common_dir()` accept a repository

Series environment: guard reliance on `the_repository` | expand

Commit Message

Patrick Steinhardt Aug. 30, 2024, 9:09 a.m. UTC 
The `get_git_common_dir()` function retrieves the path to the common
directory for `the_repository`. Make it accept a `struct repository`
such that it can work on arbitrary repositories and make it part of the
repository subsystem. This reduces our reliance on `the_repository` and
clarifies scope.
