If a user is working on master, and has merged in their feature branch, but now
has to "git pull" because master moved, with pull.rebase their feature branch
will be flattened into master.
This is because "git pull" currently does not know about rebase's preserve
merges flag, which would avoid this behavior, as it would instead replay just
the merge commit of the feature branch onto the new master, and not replay each
individual commit in the feature branch.
Add a --rebase=preserve option, which will pass along --preserve-merges to
rebase.
Also add 'preserve' to the allowed values for the pull.rebase config setting.

Convert most uses of OPT_BOOLEAN/OPTION_BOOLEAN that can use
OPT_BOOL/OPTION_BOOLEAN which have much saner semantics, and turn
remaining ones into OPT_SET_INT, OPT_COUNTUP, etc. as necessary.
* sb/parseopt-boolean-removal:
revert: use the OPT_CMDMODE for parsing, reducing code
checkout-index: fix negations of even numbers of -n
config parsing options: allow one flag multiple times
hash-object: replace stdin parsing OPT_BOOLEAN by OPT_COUNTUP
branch, commit, name-rev: ease up boolean conditions
checkout: remove superfluous local variable
log, format-patch: parsing uses OPT__QUIET
Replace deprecated OPT_BOOLEAN by OPT_BOOL
Remove deprecated OPTION_BOOLEAN for parsing arguments
Many commands use --dashed-option as a operation mode selector
(e.g. "git tag --delete") that the user can use at most one
(e.g. "git tag --delete --verify" is a nonsense) and you cannot
negate (e.g. "git tag --no-delete" is a nonsense). Make it easier
for users of parse_options() to enforce these restrictions.
* jc/parseopt-command-modes:
tag: use OPT_CMDMODE
parse-options: add OPT_CMDMODE()
Fixes a minor bug in "git rebase -i" (there could be others, as the
root cause is pretty generic) where the code feeds a random, data
dependeant string to 'echo' and expects it to come out literally.
* mm/no-shell-escape-in-die-message:
die_with_status: use "printf '%s\n'", not "echo"
Handle memory pressure and file descriptor pressure separately when
deciding to release pack windows to honor resource limits.
* bc/unuse-packfile:

sha1_file: introduce close_one_pack() to close packs on fd pressure
* da/darwin:
OS X: Fix redeclaration of die warning
Makefile: Fix APPLE_COMMON_CRYPTO with BLK_SHA1
imap-send: use Apple's Security framework for base64 encoding
* jk/fast-import-empty-ls:
fast-import: allow moving the root tree
fast-import: allow ls or filecopy of the root tree
fast-import: set valid mode on root tree in "ls"
t9300: document fast-import empty path issues
Subversion 1.8.0 that was recently released breaks older subversion
clients coming over http/https in various ways.

Git.pm: revert _temp_cache use of temp_is_locked
git-svn: allow git-svn fetching to work using serf
Git.pm: add new temp_is_locked function
"git check-ignore -z" applied the NUL termination to both its input
(with --stdin) and its output, but "git check-attr -z" ignored the
option on the output side.
This is potentially a backward incompatible fix. Let's see if
anybody screams before deciding if we want to do anything to help
existing users (there may be none).
* jc/check-x-z:
check-attr -z: a single -z should apply to both input and output
check-ignore -z: a single -z should apply to both input and output
check-attr: the name of the character is NUL, not NULL
check-ignore: the name of the character is NUL, not NULL
Add 'struct ref_update' to encode the information needed to update or
delete a ref (name, new sha1, optional old sha1, no-deref flag). Add
function 'update_refs' accepting an array of updates to perform. First
sort the input array to order locks consistently everywhere and reject
multiple updates to the same ref. Then acquire locks on all refs with
verified old values. Then update or delete all refs accordingly. Fail
if any one lock cannot be obtained or any one old value does not match.
Though the refs themselves cannot be modified together in a single
atomic transaction, this function does enable some useful semantics.
For example, a caller may create a new branch starting from the head of
another branch and rewind the original branch at the same time. This
transfers ownership of commits between branches without risk of losing
commits added to the original branch by a concurrent process, or risk of
a concurrent process creating the new branch first.

Commit 68be2fea (receive-pack, fetch-pack: reject bogus pack that
records objects twice, 2011-11-16) taught index-pack to notice and
reject duplicate objects if --strict is given (which it is for
incoming packs, if transfer.fsckObjects is set). However, it never
tested the code, because we did not have an easy way of generating
such a bogus pack.
Now that we have test infrastructure to handle this, let's confirm
that it works.

Back in 21e9757e (Hack git-add--interactive to make it work with
ActiveState Perl, 2007-08-01), the invocation of external commands was
changed to use qx{} on Windows. The rationale was that the command
interpreter on Windows is not a POSIX shell, but rather Windows's CMD.
That patch was wrong to include 'msys' in the check whether to use qx{}
or not: 'msys' identifies MSYS perl as shipped with Git for Windows,
which does not need the special treatment; qx{} should be used only with
ActiveState perl, which is identified by 'MSWin32'.

"git p4" does not support many of the view wildcards, such as * and
%%n. It only knows the common ... mapping, and exclusions.
Redo the entire wildcard code around the idea of directly querying
the p4 server for the mapping. For each commit, invoke "p4 where"
with committed file paths as args and use the client mapping to
decide where the file goes in git.
This simplifies a lot of code, and adds support for all wildcards
supported by p4. Downside is that there is probably a 20%-ish
slowdown with this approach.

When we are parsing "rev^{foo}", we check "foo" against the
various global type strings, like "commit_type",
"tree_type", etc. This is nicely abstracted, but then we
destroy the abstraction completely by using magic numbers
that must match the length of the type strings.
We could avoid these magic numbers by using skip_prefix. But
taking a step back, we can realize that using the
"commit_type" global is not really buying us anything. It is
not ever going to change from being "commit" without causing
severe breakage to existing uses. And even if it did change
for some crazy reason, we would want to evaluate its effects
on the "rev^{}" syntax, anyway.
Let's just switch these to using a custom string literal, as
we do for "rev^{object}". The resulting code is more robust
to changes in the type strings, and is more readable.

Complete the <rev>^{<type>} family of object descriptors by having
<rev>^{tag} dereference <rev> until a tag object is found (or fail if
unable).
At first glance this may not seem very useful, as commits, trees, and
blobs cannot be peeled to a tag, and a tag would just peel to itself.
However, this can be used to ensure that <rev> names a tag object:
$ git rev-parse --verify v1.8.4^{tag}
04f013dc38
$ git rev-parse --verify master^{tag}
error: master^{tag}: expected tag type, but the object dereferences to tree type
fatal: Needed a single revision
Users can already ensure that <rev> is a tag object by checking the
output of 'git cat-file -t <rev>', but:
* users may expect <rev>^{tag} to exist given that <rev>^{commit},
<rev>^{tree}, and <rev>^{blob} all exist
* this syntax is more convenient/natural in some circumstances

Use test_cmp instead of passing two command substitutions to the
"test" builtin. This way:
- when tests fail, they can print a helpful diff if run with
"--verbose"
- the argument order "test_cmp expect actual" feels natural,
unlike test <known> = <unknown> that seems backwards
- the exit status from invoking git is checked, so if rev-parse
starts segfaulting then the test will notice and fail
Use a custom function for this instead of test_cmp_rev to emphasize
that we are testing the output from "git rev-parse" with certain
arguments, not checking that the revisions are equal in abstract.

Since 664059fb (transport-helper: update remote helper namespace,
2013-04-17), a 'push' operation on a remote helper updates the
private ref by default. This is often a good thing, but it can also
be desirable to disable this update to force the next 'pull' to
re-import the pushed revisions.
Allow remote-helpers to disable the automatic update by introducing a new
capability.

This is useful to make sure we don't step outside the boundaries of what
we are interpreting at the moment. For example while interpreting
foobar@{u}~1, the job of interpret_branch_name() ends right before ~1,
but there's no way to figure that out inside the function, unless the
len argument is passed.
