Rebasing onto many changes is interesting, but it's also
interesting to see what happens when rebasing many changes.
And while at it, let's also look at the impact of using a
split index.

When split-index is being used, we have two cache_entry arrays in
index_state->cache[] and index_state->split_index->base->cache[].
index_state->cache[] may share the same entries with base->cache[] so
we can quickly determine what entries are shared. This makes memory
management tricky, we can't free base->cache[] until we know
index_state->cache[] does not point to any of those entries.
unshare_split_index() is added for this purpose, to find shared
entries and either duplicate them in index_state->cache[], or discard
them. Either way it should be safe to free base->cache[] after
unshare_split_index().

Completion for "git checkout <branch>" that auto-creates the branch

The building of the reflog message is using strbuf, which is not
friendly with internationalization frameworks. No other reflog
messages are translated right now and switching all the messages to
i18n would require a major rework of the way the messages are built.

Listing the specific hooks might feel verbose but without it the
reader is left to wonder which hooks are triggered during the
push. Something which is not immediately obvious when only trying

In the scripted version of the interactive rebase, there was no internal
representation of the todo list; it was re-read before every command.
That allowed the hack that an `exec` command could append (or even
completely rewrite) the todo list.
This hack was broken by the partial conversion of the interactive rebase
to C, and this patch reinstates it.
We also add a small test to verify that this fix does not regress in the
future.

The internals of the refs API around the cached refs has been
streamlined.

do_for_each_entry_in_dir(): delete function
files_pack_refs(): use reference iteration

get_loose_ref_dir(): function renamed from get_loose_refs()
do_for_each_entry_in_dir(): eliminate `offset` argument
refs: handle "refs/bisect/" in `loose_fill_ref_dir()`
ref-cache: use a callback function to fill the cache
refs: record the ref_store in ref_cache, not ref_dir
ref-cache: introduce a new type, ref_cache
refs: split `ref_cache` code into separate files
ref-cache: rename `remove_entry()` to `remove_entry_from_dir()`
ref-cache: rename `find_ref()` to `find_ref_entry()`
ref-cache: rename `add_ref()` to `add_ref_entry()`

Our array-reverse algorithm does the usual "walk from both
ends, swapping elements". We can quit when the two indices
are equal, since:
1. Swapping an element with itself is a noop.
2. If i and j are equal, then in the next iteration i is
guaranteed to be bigge than j, and we will exit the
loop.
So exiting the loop on equality is slightly more efficient.
And more importantly, the new SWAP() macro does not expect
to handle noop swaps; it will call memcpy() with the same src
and dst pointers in this case. It's unclear whether that
causes a problem on any platforms by violating the
"overlapping memory" constraint of memcpy, but it does cause
valgrind to complain.

When we init a submodule, we try to die when it has no URL
defined:
url = xstrdup(sub->url);
if (!url)
die(...);
But that's clearly nonsense. xstrdup() will never return
NULL, and if sub->url is NULL, we'll segfault.
These two bits of code need to be flipped, so we check
sub->url before looking at it.
