rerere: Separate libgit and builtin functions
This patch moves rerere()-related functions into a newly created

The setup_rerere() function is needed by both rerere() and cmd_rerere(),
so this function is moved to rerere.c and declared non-static (and "extern")
in newly created rerere.h file.

builtin-rerere: more carefully find conflict markers
When a conflicting file contains a line that begin with "=======", rerere
failed to parse conflict markers. This result to a wrong preimage file and
an unexpected error for the user. The boundary between ours and theirs
not just begin with 7 equals, but is followed by either a SP or a LF.
This patch enforces parsing rules so that markers match in the right order,
and when ambiguous, the command does not autoresolve the conflicted file.
Especially because we are introducing rerere.autoupdate configuration
(which is off by default for safety) that automatically stages the
resolution made by rerere, it is necessary to make sure that we do not
autoresolve when there is any ambiguity.

apply: fix copy/rename breakage
7ebd52a (Merge branch 'dz/apply-again', 2008-07-01) taught "git-apply" to
grok a (non-git) patch that is a concatenation of separate patches that
touch the same file number of times, by recording the postimage of patch
application of previous round and using it as the preimage for later
rounds.
This "incremental" mode of patch application fundamentally contradicts
with the way git rename/copy patches are designed. When a git patch talks
about a file A getting modified, and a new file B created out of A, like
this:
diff --git a/A b/A
--- a/A
+++ b/A
... change text here ...
diff --git a/A b/B
copy from A
copy to B
--- a/A
+++ b/B
... change text here ...
the second change to produce B does not depend on what is done to A with
the first change in any way. This is explicitly done so for reviewability
of individual patches.
With this commit, we do not look at 'fn_table' that records the postimage
of previous round when applying a patch to produce a new file out of an
existing file.

Correct pack memory leak causing git gc to try to exceed ulimit
When recursing to unpack a delta base we must unuse_pack() so that
the pack window for the current object does not remain pinned in
memory while the delta base is itself being unpacked and materialized
for our use.
On a long delta chain of 50 objects we may need to access 6 different
windows from a very large (>3G) pack file in order to obtain all
of the delta base content. If the process ulimit permits us to
map/allocate only 1.5G we must release windows during this recursion
to ensure we stay within the ulimit and transition memory from pack
cache to standard malloc, or other mmap needs.
Inserting an unuse_pack() call prior to the recursion allows us to
avoid pinning the current window, making it available for garbage
collection if memory runs low.
This has been broken since at least before 1.5.1-rc1, and very
likely earlier than that. Its fixed now. :)

avoid null SHA1 in oldest reflog
When the user specifies a ref by a reflog entry older than
one we have (e.g., "HEAD@{20 years ago"}), we issue a
warning and give them the "from" value of the oldest reflog
entry. That is, we say "we don't know what happened before
this entry, but before this we know we had some particular
SHA1".
However, the oldest reflog entry is often a creation event
such as clone or branch creation. In this case, the entry
claims that the ref went from "00000..." (the null sha1) to
the new value, and the reflog lookup returns the null sha1.
While this is technically correct (the entry tells us that
the ref didn't exist at the specified time) it is not
terribly useful to the end user. What they probably want
instead is "the oldest useful sha1 that this ref ever had".
This patch changes the behavior such that if the oldest ref
would return the null sha1, it instead returns the first
value the ref ever had.
We never discovered this problem in the test scripts because
we created "fake" reflogs that had only a specified segment
of history. This patch updates the tests with a creation
event at the beginning of history.

make deleting a missing ref more quiet
If git attempts to delete a ref, but the unlink of the ref
file fails, we print a message to stderr. This is usually a
good thing, but if the error is ENOENT, then it indicates
that the ref has _already_ been deleted. And since that's
our goal, it doesn't make sense to complain to the user.
This harmonizes the error reporting behavior for the
unpacked and packed cases; the packed case already printed
nothing on ENOENT, but the unpacked printed unconditionally.
Additionally, send-pack would, when deleting the tracking
ref corresponding to a remote delete, print "Failed to
delete" on any failure. This can be a misleading
message, since we actually _did_ delete at the remote side,
but we failed to delete locally. Rather than make the
message more precise, let's just eliminate it entirely; the
delete_ref routine already takes care of printing out a much
more specific message about what went wrong.

Allow per-command pager config
There is great debate over whether some commands should set
up a pager automatically. This patch allows individuals to
set their own pager preferences for each command, overriding
the default. For example, to disable the pager for git
status:
git config pager.status false
If "--pager" or "--no-pager" is specified on the command
line, it takes precedence over the config option.
There are two caveats:
- you can turn on the pager for plumbing commands.
Combined with "core.pager = always", this will probably
break a lot of things. Don't do it.
- This only works for builtin commands. The reason is
somewhat complex:
Calling git_config before we do setup_git_directory
has bad side effects, because it wants to know where
the git_dir is to find ".git/config". Unfortunately,
we cannot call setup_git_directory indiscriminately,
because some builtins (like "init") break if we do.
For builtins, this is OK, since we can just wait until
after we call setup_git_directory. But for aliases, we
don't know until we expand (recursively) which command
we're doing. This should not be a huge problem for
aliases, which can simply use "--pager" or "--no-pager"
in the alias as appropriate.
For external commands, however, we don't know we even
have an external command until we exec it, and by then
it is too late to check the config.
An alternative approach would be to have a config mode
where we don't bother looking at .git/config, but only
at the user and system config files. This would make the
behavior consistent across builtins, aliases, and
external commands, at the cost of not allowing per-repo
pager config for at all.
