submodule: try harder to fetch needed sha1 by direct fetching sha1
When reviewing a change that also updates a submodule in Gerrit, a
common review practice is to download and cherry-pick the patch
locally to test it. However when testing it locally, the 'git
submodule update' may fail fetching the correct submodule sha1 as
the corresponding commit in the submodule is not yet part of the
project history, but also just a proposed change.
If $sha1 was not part of the default fetch, we try to fetch the $sha1
directly. Some servers however do not support direct fetch by sha1,
which leads git-fetch to fail quickly. We can fail ourselves here as
the still missing sha1 would lead to a failure later in the checkout
stage anyway, so failing here is as good as we can get.

merge-tree: drop generate_common strategy
When merge_blobs sees an add/add conflict, it tries to
create a virtual base object for the 3-way merge that
consists of the common lines of each file. It inherited this
strategy from merge-one-file in
0c79938 (Improved three-way
blob merging code, 2006-06-28), and the point is to minimize
the size of the conflict hunks. That commit talks about "if
libxdiff were to ever grow a compatible three-way merge, it
could probably be directly plugged in".
That has long since happened. So as with merge-one-file in
the previous commit, this extra step is no longer necessary.
Our 3-way merge code is smart enough to do the minimizing
itself if we simply feed it an empty base, which is what the
more modern merge-recursive strategy already does.
Not only does this let us drop some code, but it removes an
overflow bug in generate_common_file(). We allocate a buffer
as large as the smallest of the two blobs, under the
assumption that there cannot be more common content than
what is in the smaller blob. However, xdiff may feed us
more: if neither file ends in a newline, it feeds us the
"\nNo newline at end of file" marker as common content, and
we write it into the output. If the differences between the
files are small than that string, we overflow the output
buffer. This patch solves it by simply dropping the buggy
code entirely.

merge-one-file: use empty blob for add/add base
When we see an add/add conflict on a file, we generate the
conflicted content by doing a 3-way merge with a "virtual"
base consisting of the common lines of the two sides. This
strategy dates back to
cb93c19 (merge-one-file: use common
as base, instead of emptiness., 2005-11-09).
Back then, the next step was to call rcs merge to generate
the 3-way conflicts. Using the virtual base produced much
better results, as rcs merge does not attempt to minimize
the hunks. As a result, you'd get a conflict with the
entirety of the files on either side.
Since then, though, we've switched to using git-merge-file,
which uses xdiff's "zealous" merge. This will find the
minimal hunks even with just the simple, empty base.
Let's switch to using that empty base. It's simpler, more
efficient, and reduces our dependencies (we no longer need a
working diff binary). It's also how the merge-recursive
strategy handles this same case.
We can almost get rid of git-sh-setup's create_virtual_base,
but we don't here, for two reasons:
1. The functions in git-sh-setup are part of our public
interface, so it's possible somebody is depending on
it. We'd at least need to deprecate it first.
2. It's also used by mergetool's p4merge driver. It's
unknown whether its 3-way merge is as capable as git's;
if not, then it is benefiting from the function.

exec() or exit() immediately, so the leak isn't a big deal.
On Windows, though, we use spawn() from the parent process,

submodule--helper: die on config error when cloning module
When setting the 'core.worktree' option for a newly cloned
submodule we ignore the return value of `git_config_set_in_file`.
As this leaves the submodule in an inconsistent state, we instead
want to inform the user that something has gone wrong by printing
an error and aborting the program.

submodule: die on config error when linking modules
When trying to connect a submodule with its corresponding
repository in '.git/modules' we try to set the core.worktree
setting in the submodule, which may fail due to an error
encountered in `git_config_set_in_file`.
The function is used in the git-mv command when trying to move a
submodule to another location. We already die when renaming a
file fails but do not pay attention to the case where updating
the connection between submodule and its repository fails. As
this leaves the repository in an inconsistent state, as well,
abort the program by dying early and presenting the failure to
the user.

branch: die on config error when unsetting upstream
When we try to unset upstream configurations we do not check
return codes for the `git_config_set` functions. As those may
indicate that we were unable to unset the respective
configuration we may exit successfully without any error message
while in fact the upstream configuration was not unset.
Fix this by dying with an error message when we cannot unset the
configuration.

branch: report errors in tracking branch setup
When setting up a new tracking branch fails due to issues with
the configuration file we do not report any errors to the user
and pretend setting the tracking branch succeeded.
Setting up the tracking branch is handled by the
`install_branch_config` function. We do not want to simply die
there as the function is not only invoked when explicitly setting
upstream information with `git branch --set-upstream-to=`, but
also by `git push --set-upstream` and `git clone`. While it is
reasonable to die in the explict first case, we would lose
information in the latter two cases, so we only print the error
message but continue the program as usual.

config: add '--show-origin' option to print the origin of a config value
If config values are queried using 'git config' (e.g. via --get,
--get-all, --get-regexp, or --list flag) then it is sometimes hard to
find the configuration file where the values were defined.
Teach 'git config' the '--show-origin' option to print the source
configuration file for every printed value.

The handle_builtin() starts from stripping of command extension if

git-svn: apply "svn.pathnameencoding" before URL encoding
The conversion from "svn.pathnameencoding" to UTF-8 should be applied
first, and then URL encoding should be applied on the resulting UTF-8

makes non-UTF-8 URL which causes error from Subversion such as
