Merge branch 'sb/hashmap-cleanup'
Many uses of comparision callback function the hashmap API uses cast the callback function type when registering it to hashmap_init(), which defeats the compile time type checking when the callback interface changes (e.g. gaining more parameters). The callback implementations have been updated to take "void *" pointers and cast them to the type they expect instead. * sb/hashmap-cleanup: t/helper/test-hashmap: use custom data instead of duplicate cmp functions name-hash.c: drop hashmap_cmp_fn cast submodule-config.c: drop hashmap_cmp_fn cast remote.c: drop hashmap_cmp_fn cast patch-ids.c: drop hashmap_cmp_fn cast convert/sub-process: drop cast to hashmap_cmp_fn config.c: drop hashmap_cmp_fn cast builtin/describe: drop hashmap_cmp_fn cast builtin/difftool.c: drop hashmap_cmp_fn cast attr.c: drop hashmap_cmp_fn cast
