After running "git pull $there for-linus" to merge a signed tag, the
integrator may need to amend the resulting merge commit to fix typoes
in it. Teach --amend option to read the existing extra headers, and

Now that we allow pulling a tag from the remote site to validate the
authenticity, we should give the user the final chance to verify and edit
the merge message. The integrator is expected to leave a meaningful merge
commit log in the history. Disallow fast-forwarding in such a case to
ensure that a merge commit is always recorded.

Now MERGE_HEAD records the tag objects without peeling, we could record
the result of manual conflict resolution via "git commit" without losing
the tag information. Introduce a new "mergetag" multi-line header field to
the commit object, and use it to store the entire contents of each signed
tag merged.
A commit header that has a multi-line payload begins with the header tag
(e.g. "mergetag" in this case), SP, the first line of payload, LF, and all
the remaining lines have a SP inserted at the beginning.
In hindsight, it would have been better to make "merge --continue" as the
way to continue from such an interrupted merge, not "commit", but this is
a backward compatibility baggage we would need to carry around for now.

The integrator tool will start allowing to pull a signed or an annotated
tag, i.e.
$ git pull $there tags/for-linus
and the description in the tag is used to convey a meaningful message from
the lieutenant to the integrator to justify the history being pulled.
Include the message in the pull request e-mail, as the same information is
useful in this context, too. It would encourage the lieutenants to write
meaningful messages in their signed tags.

Otherwise, "git commit" wouldn't have a way to tell that we were in the

The merge-recursive code uses the commit->util field directly to annotate
the commit objects given from the command line, i.e. the remote heads to
be merged, with a single string to be used to describe it in its trace
messages and conflict markers.
Correct this short-signtedness by redefining the field to be a pointer to
a structure "struct merge_remote_desc" that later enhancements can add
more information. Store the original objects we were told to merge in a
field "obj" in this struct, so that we can recover the tag we were told to
merge.

When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.
E.g. a signed tag "for-linus" can be created, and the integrator can run:
$ git pull git://example.com/work.git/ for-linus
This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.
Update fmt-merge-msg so that it pre-fills the merge message template with
the body (but not signature) of the tag object to help the integrator write
a better merge message, in the same spirit as the existing merge.log summary
lines.
The message that comes from GPG signature validation is also included in
the merge message template to help the integrator verify it, but they are
prefixed with "#" to make them comments.

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".
When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.
Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.
So for the same reason as we added rule to allow "git fetch $there v1.0"
instead of "git fetch $there tags/v1.0" in the previous commit, here is a
bit longer rope for the users, which incidentally simplifies our code.

Currently we either need to set branch.<name>.rebase for existing
branches if we'd like "git pull" to mean "git pull --rebase", or have
the forethought of setting "branch.autosetuprebase" before we create
the branch.
Introduce a "pull.rebase" option to globally configure "git pull" to
mean "git pull --rebase" for any branch.
This option will be considered at a lower priority than
branch.<name>.rebase, i.e. we could set pull.rebase=true and
branch.<name>.rebase=false and the latter configuration option would
win.

During verify_pack() all objects are read for SHA-1 check. Then
fsck_sha1() is called on every object, which read the object again
(fsck_sha1 -> parse_object -> read_sha1_file).
Avoid reading an object twice, do fsck_sha1 while we have an object
uncompressed data in verify_pack.

The config options core.packedGitWindowSize, core.packedGitLimit,
core.deltaBaseCacheLimit, core.bigFileThreshold, pack.windowMemory and
pack.packSizeLimit all claim to support suffixes up to and including
'g'. This implies that they should accept sizes >=2G on 64-bit
systems: certainly, specifying a size of 3g should not silently be
translated to zero or transformed into a large negative value due to
integer overflow. However, due to use of git_config_int() rather than
git_config_ulong(), that is exactly what happens:
% git config core.bigFileThreshold 2g
% git gc --aggressive # with extra debugging code to print out
# core.bigfilethreshold after parsing
bigfilethreshold: -2147483648
[...]
This is probably irrelevant for core.deltaBaseCacheLimit, but is
problematic for the other values. (It is particularly problematic for
core.packedGitLimit, which can't even be set to its default value in
the config file due to this bug.)
This fixes things for 32-bit platforms as well. They get the usual bad
config error if an overlarge value is specified, e.g.:
fatal: bad config value for 'core.bigfilethreshold' in /home/nix/.gitconfig
This is detected in all cases, even if the 32-bit platform has no size
larger than 'long'. For signed integral configuration values, we also
detect the case where the value is too large for the signed type but
not the unsigned type.

This mostly moves existing code from builtin/tag.c (for signing)
and builtin/verify-tag.c (for verifying) to a new gpg-interface.c
file to provide a more generic library interface.
- sign_buffer() takes a payload strbuf, a signature strbuf, and a signing
key, runs "gpg" to produce a detached signature for the payload, and
appends it to the signature strbuf. The contents of a signed tag that
concatenates the payload and the detached signature can be produced by
giving the same strbuf as payload and signature strbuf.
- verify_signed_buffer() takes a payload and a detached signature as
<ptr, len> pairs, and runs "gpg --verify" to see if the payload matches
the signature. It can optionally capture the output from GPG to allow
the callers to pretty-print it in a way more suitable for their
contexts.
"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is
annotated. The updated run_gpg_verify() function detects the lack of
detached signature in the input, and errors out without bothering "gpg".
