If the repo is empty, it is obvious that there are no common commits
when fetching from _anywhere_.
So there is no use in saying it in that case, and it can even be
annoying. Therefore suppress the message unilaterally if the repository
is empty prior to the fetch.

bash completion: Resolve git show ref:path<tab> losing ref: portion

bash completion: Don't offer "a.." as a completion for "a."
bash completion: Improve responsiveness of git-log completion
When "rebase -i -p" tries to preserve merges of unrelated branches, it
lost some parents:
- When you have more than two parents, the commit in the new history
ends up with fewer than expected number of parents and this breakage
goes unnoticed;
- When you are rebasing a merge with two parents and one is lost, the
command tries to cherry-pick the original merge commit, and the command
fails.

The manual page of git-cherry-pick and git-revert asserts that -n works
primarily on the working tree, while in fact the primary object it operates
on is the index, and the changes only "accidentally" propagate to the
working tree. This e.g. leads innocent #git IRC folks to believe that you
can use -n to prepare changes for git-add -i staging.

Replace the code that calls backend specific argument parsers by a

We can add back such a mechanism (based on incremental parse_opt(),
perhaps) when we need it. The compression level parameter, though,
is going to be shared by future compressing backends like tgz.

Now that all file attribute handling for git archive has moved to archive.c,
we can unexport sha1_file_to_archive() and is_archive_path_ignored() even
disappears.
Add setup_archive_check(), modelled after similar functions used in the code
of other commands that support multiple file attributes.
Also remove convert_to_archive(), as it's only remaining function with
attribute handling gone was to call format_subst() if commit was not NULL,
which is now checked in sha1_file_to_archive().

Add the exported function write_archive_entries() to archive.c, which uses
the new ability of read_tree_recursive() to pass a context pointer to its
callback in order to centralize previously duplicated code.
The new callback function write_archive_entry() does the work that every
archiver backend needs to do: loading file contents, entering subdirectories,
handling file attributes, constructing the full path of the entry. All that
done, it calls the backend specific write_archive_entry_fn_t function.

If we are trying to resolve deltas for a long delta chain composed
of multi-megabyte objects we can easily run into requiring 500M+
of memory to hold each object in the chain on the call stack while
we recurse into the dependent objects and resolve them.
We now use a simple delta cache that discards objects near the
bottom of the call stack first, as they are the most least recently
used objects in this current delta chain. If we recurse out of a
chain we may find the base object is no longer available, as it was
free'd to keep memory under the deltaBaseCacheLimit. In such cases
we must unpack the base object again, which will require recursing
back to the root of the top of the delta chain as we released that
root first.
The astute reader will probably realize that we can still exceed
the delta base cache limit, but this happens only if the most
recent base plus the delta plus the inflated dependent sum up to
more than the base cache limit. Due to the way patch_delta is
currently implemented we cannot operate in less memory anyway.

If we free the data stored within a base_data we need the struct
object_entry to get the data back again for use with another dependent
delta. Storing the object_entry* in base_data makes it simple to call
get_data_from_pack() to recover the compressed information.
This however means that we must add the missing base object to the end of
our packfile prior to calling resolve_delta() on each of the dependent
deltas. Adding the base first ensures we can read the base back from the
pack we are indexing, as if it had been included by the remote side.

We need to release earlier inflated base objects when memory gets
low, which means we need to be able to walk up or down the stack
to locate the objects we want to release, and free their data.
The new link/unlink routines allow inserting and removing the struct
base_data during recursion inside resolve_delta, and the global
base_cache gives us the head of the chain (bottom of the stack)
so we can traverse it.

We need to discard base objects which are not recently used if our
memory gets low, such as when we are unpacking a long delta chain
of a very large object.
To support tracking the available base objects we combine the
pointer and size into a struct. Future changes would allow the
data pointer to be free'd and marked NULL if memory gets low.
