This series continues the libification effort by migrating the global
string variable 'excludes_file' into 'struct repo_config_values'. Since
this is a dynamically allocated variable, the migration requires proper
heap memory management.

The series is structured in two commits:

 - Abstract the XDG fallback lazy-loading logic out of dir.c into a proper
getter.

 - Move the variable into the struct and introducs 'repo_config_values_clear()'.

Note on Submodules: A temporary shield 'if (repo != the_repository)' is
included in both the getter and the clear function. This prevents
uninitialized submodules from triggering the BUG() assertion.
