Edward Thomson 18e71e6d 2018-11-28T13:31:06 index: use new enum and structure names Use the new-style index names throughout our own codebase.
Patrick Steinhardt f2f5ec84 2018-11-23T19:27:09 khash: move khash include into implementation files The current map implementations directly include the "khash.h" headers into their own headers to make available a set of static functions, defines et cetera. Besides leaking the complete khash namespace into files wherever khashes are used, this also triggers Clang's -Wunused-function warnings when some of the static functions are not being used at all. Fix the issue by moving the includes into the respective map implementation files. Add forward declares for all the map types to make them known.

While this is most certainly sensible in most cases, we should prefer the more obvious behavior, namingly leaving the map pointer intact. Furthermore, this macro has been refactored incorrectly during the map-refactorings: the two statements are not actually grouped together by a `do { ... } while (0)` block, as it is required for macros to match the behavior of functions more closely. This has led to at least one subtle nesting error in `pack-objects.c`. The following code block ``` if (pb->object_ix) git_oidmap_free(pb->object_ix); ``` would be expanded to ``` if (pb->object_ix) git_oidmap__free(pb->object_ix); pb->object_ix = NULL; ``` which is not what one woudl expect. While it is not a bug here as it would simply become a no-op, the wrong implementation could lead to bugs in other occasions. Fix this by simply removing the macro altogether and replacing it with real function calls. This leaves the burden of setting the pointer to NULL afterwards to the caller, but this is actually expected and behaves like other `free` functions.
