Replace the accesses to the global 'ignore_case' variable with
calls to 'repo_get_ignore_case(the_repository)'. This step eliminates
the 'ignore_case' global state.
Note on compat/win32/path-utils.c:
To eliminate the global state, several helper functions
(e.g. 'win32_fspathncmp()') now read from
'repo_get_ignore_case(the_repository)'. While this introduces
dependency on 'repository.h' into the 'compat/', it avoids massive
refactoring of the signatures across the codebase.
