A finishing touch to fix breakage to "add -e" caused by defaulting

After 4c7f1819 (make color.ui default to 'auto', 2013-06-10), the
patch file to be edited during 'git add -e' receives all the color
codes. This is because diffopt.use_color defaults to -1, which
causes want_color to now return 'auto'.
By explicitly setting use_color to 0, we can ensure the diff output
has no color codes in it.

There are only four (with some generous rounding) instances in the
current source code where we speak of "subproject" instead of
"submodule". They are as follows:
* one error message in git-apply and two in entry.c
* the patch format for submodule changes
The latter was introduced in 0478675 (Expose subprojects as special
files to "git diff" machinery, 2007-04-15), apparently before the
terminology was settled. We can of course not change the patch
format.

If we get an input line to --batch or --batch-check that
looks like "HEAD foo bar", we will currently feed the whole
thing to get_sha1(). This means that to use --batch-check
with `rev-list --objects`, one must pre-process the input,
like:
git rev-list --objects HEAD |
cut -d' ' -f1 |
git cat-file --batch-check
Besides being more typing and slightly less efficient to
invoke `cut`, the result loses information: we no longer
know which path each object was found at.
This patch teaches cat-file to split input lines at the
first whitespace. Everything to the left of the whitespace
is considered an object name, and everything to the right is
made available as the %(reset) atom. So you can now do:
git rev-list --objects HEAD |
git cat-file --batch-check='%(objectsize) %(rest)'
to collect object sizes at particular paths.
Even if %(rest) is not used, we always do the whitespace
split (which means you can simply eliminate the `cut`
command from the first example above).
This whitespace split is backwards compatible for any
reasonable input. Object names cannot contain spaces, so any
input with spaces would have resulted in a "missing" line.
The only input hurt is if somebody really expected input of
the form "HEAD is a fine-looking ref!" to fail; it will now
parse HEAD, and make "is a fine-looking ref!" available as
%(rest).

This atom is just like %(objectsize), except that it shows
the on-disk size of the object rather than the object's true
size. In other words, it makes the "disk_size" query of
sha1_object_info_extended available via the command-line.
This can be used for rough attribution of disk usage to
particular refs, though see the caveats in the
documentation.
This patch does not include any tests, as the exact numbers
returned are volatile and subject to zlib and packing
decisions. We cannot even reliably guarantee that the
on-disk size is smaller than the object content (though in
general this should be the case for non-trivial objects).

The `cat-file --batch-check` command can be used to quickly
get information about a large number of objects. However, it
provides a fixed set of information.
This patch adds an optional <format> option to --batch-check
to allow a caller to specify which items they are interested
in, and in which order to output them. This is not very
exciting for now, since we provide the same limited set that
you could already get. However, it opens the door to adding
new format items in the future without breaking backwards
compatibility (or forcing callers to pay the cost to
calculate uninteresting items).
Since the --batch option shares code with --batch-check, it
receives the same feature, though it is less likely to be of
interest there.
The format atom names are chosen to match their counterparts
in for-each-ref. Though we do not (yet) share any code with
for-each-ref's formatter, this keeps the interface as
consistent as possible, and may help later on if the
implementations are unified.

Earlier remote.pushdefault (and per-branch branch.*.pushremote)
were introduced as an additional mechanism to choose what
repository to push into when "git push" did not say it from the
command line, to help people who push to a repository that is
different from where they fetch from. This attempts to finish that
topic by teaching the default mechanism to choose branch in the
remote repository to be updated by such a push.
The 'current', 'matching' and 'nothing' modes (specified by the
push.default configuration variable) extend to such a "triangular"
workflow naturally, but 'upstream' and 'simple' have to be updated.
. 'upstream' is about pushing back to update the branch in the
remote repository that the current branch fetches from and
integrates with, it errors out in a triangular workflow.
. 'simple' is meant to help new people by avoiding mistakes, and
will be the safe default in Git 2.0.
In a non-triangular workflow, it will continue to act as a cross
between 'upstream' and 'current' in that it pushes to the current
branch's @{upstream} only when it is set to the same name as the
current branch (e.g. your 'master' forks from the 'master' from
the central repository).
In a triangular workflow, this series tentatively defines it as
the same as 'current', but we may have to tighten it to avoid
surprises in some way.

The regular "git cat-file -p" and "git cat-file blob" code
paths already learned to stream large blobs. Let's do the
same here.
Note that this means we look up the type and size before
making a decision of whether to load the object into memory
or stream (just like the "-p" code path does). That can lead
to extra work, but it should be dwarfed by the cost of
actually accessing the object itself. In my measurements,
there was a 1-2% slowdown when using "--batch" on a large
number of objects.

I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:

Commit 0433ad1 (clone: run check_everything_connected,
2013-03-25) added the same connectivity check to clone that
we use for fetching. The intent was to provide enough safety
checks that "git clone git://..." could be counted on to
detect bit errors and other repo corruption, and not
silently propagate them to the clone.
For local clones, this turns out to be a bad idea, for two
reasons:
1. Local clones use hard linking (or even shared object
stores), and so complete far more quickly. The time
spent on the connectivity check is therefore
proportionally much more painful.
2. Local clones do not actually meet our safety guarantee
anyway. The connectivity check makes sure we have all
of the objects we claim to, but it does not check for
bit errors. We will notice bit errors in commits and
trees, but we do not load blob objects at all. Whereas
over the pack transport, we actually recompute the sha1
of each object in the incoming packfile; bit errors
change the sha1 of the object, which is then caught by
the connectivity check.
This patch drops the connectivity check in the local case.
Note that we have to revert the changes from 0433ad1 to
t5710, as we no longer notice the corruption during clone.
We could go a step further and provide a "verify even local
clones" option, but it is probably not worthwhile. You can
already spell that as "cd foo.git && git fsck && git clone ."
or as "git clone --no-local foo.git".

Format-patch generates emails with the "From" address set to the
author of each patch. If you are going to send the emails, however,
you would want to replace the author identity with yours (if they
are not the same), and bump the author identity to an in-body
header.
Normally this is handled by git-send-email, which does the
transformation before sending out the emails. However, some
workflows may not use send-email (e.g., imap-send, or a custom
script which feeds the mbox to a non-git MUA). They could each
implement this feature themselves, but getting it right is
non-trivial (one must canonicalize the identities by reversing any
RFC2047 encoding or RFC822 quoting of the headers, which has caused
many bugs in send-email over the years).
This patch takes a different approach: it teaches format-patch a
"--from" option which handles the ident check and in-body header
while it is writing out the email. It's much simpler to do at this
level (because we haven't done any quoting yet), and any workflow
based on format-patch can easily turn it on.

These three options mean "favor fast-forwarding when possible,
without creating an unnecessary merge", "never fast-forward and
always create a merge commit even when the commit being merged is a
strict descendant", and "we do not want to create any merge commit;
update only when the merged commit is a strict descendant".
They are "pick one out of these three possibilities" options, and
correspond to "merge.ff" configuration that is tri-state (yes, no
and only).
However, the implementation did not follow the usual convention for
the command line options (later one wins, and command line overrides
what is in the configuration).
Fix this by consolidating two variables (fast_forward_only and
allow_fast_forward) used in the implementation into one enum that
can take one of the three possible values.
