Most operations that iterate over refs are happy to ignore
broken cruft. However, some operations should be performed
with knowledge of these broken refs, because it is better
for the operation to choke on a missing object than it is to
silently pretend that the ref did not exist (e.g., if we are
computing the set of reachable tips in order to prune
objects).
These processes could just call for_each_rawref, except that
ref iteration is often hidden behind other interfaces. For
instance, for a destructive "repack -ad", we would have to
inform "pack-objects" that we are destructive, and then it
would in turn have to tell the revision code that our
"--all" should include broken refs.
It's much simpler to just set a global for "dangerous"
operations that includes broken refs in all iterations.

Credential helpers are asked in turn until one of them give
positive response, which is cumbersome to turn off when you need to
run Git in an automated setting. The credential helper interface
learned to allow a helper to say "stop, don't ask other helpers."
Also GIT_TERMINAL_PROMPT environment can be set to false to disable
our built-in prompt mechanism for passwords.
* jk/credential-quit:
prompt: respect GIT_TERMINAL_PROMPT to disable terminal prompts
credential: let helpers tell us to quit
Allow passing extra set of arguments when ssh is invoked to create
an encrypted & authenticated connection by introducing a new environment
variable GIT_SSH_COMMAND, whose contents is interpreted by shells.
This is not possible with existing GIT_SSH mechanism whose
invocation bypasses shells, which was designed more to match what
other programs with similar variables did, not necessarily to be
more useful.
* tq/git-ssh-command:
git_connect: set ssh shell command in GIT_SSH_COMMAND
If you run git as part of an automated system, you might
prefer git to die rather than try to issue a prompt on the
terminal (because there would be nobody to see it and
respond, and the process would hang forever).
This usually works out of the box because getpass() (and our
more featureful replacements) will fail when there is no
tty, but this does not cover all cases. For example, a batch
system run via ssh might have a tty, even when the user does
not expect it.
Let's provide an environment variable the user can set to
avoid even trying to touch the tty at all.

"git checkout --to" sets up a new working directory with a .git file
pointing to $GIT_DIR/worktrees/<id>. It then executes "git checkout"
again on the new worktree with the same arguments except "--to" is
taken out. The second checkout execution, which is not contaminated
with any info from the current repository, will actually check out and
everything that normal "git checkout" does.

This variable is intended to support multiple working directories
attached to a repository. Such a repository may have a main working
directory, created by either "git init" or "git clone" and one or more
linked working directories. These working directories and the main
repository share the same repository directory.
In linked working directories, $GIT_COMMON_DIR must be defined to point
to the real repository directory and $GIT_DIR points to an unused
subdirectory inside $GIT_COMMON_DIR. File locations inside the
repository are reorganized from the linked worktree view point:
- worktree-specific such as HEAD, logs/HEAD, index, other top-level
refs and unrecognized files are from $GIT_DIR.
- the rest like objects, refs, info, hooks, packed-refs, shallow...
are from $GIT_COMMON_DIR (except info/sparse-checkout, but that's
a separate patch)
Scripts are supposed to retrieve paths in $GIT_DIR with "git rev-parse
--git-path", which will take care of "$GIT_DIR vs $GIT_COMMON_DIR"
business.
The redirection is done by git_path(), git_pathdup() and
strbuf_git_path(). The selected list of paths goes to $GIT_COMMON_DIR,
not the other way around in case a developer adds a new
worktree-specific file and it's accidentally promoted to be shared
across repositories (this includes unknown files added by third party
commands)
The list of known files that belong to $GIT_DIR are:
ADD_EDIT.patch BISECT_ANCESTORS_OK BISECT_EXPECTED_REV BISECT_LOG
BISECT_NAMES CHERRY_PICK_HEAD COMMIT_MSG FETCH_HEAD HEAD MERGE_HEAD
MERGE_MODE MERGE_RR NOTES_EDITMSG NOTES_MERGE_WORKTREE ORIG_HEAD
REVERT_HEAD SQUASH_MSG TAG_EDITMSG fast_import_crash_* logs/HEAD
next-index-* rebase-apply rebase-merge rsync-refs-* sequencer/*
shallow_*
Path mapping is NOT done for git_path_submodule(). Multi-checkouts are
not supported as submodules.

It may be impractical to install a wrapper script for GIT_SSH
when additional parameters need to be passed. Provide an alternative
way of specifying a shell command to be run, including command line
arguments, by means of the GIT_SSH_COMMAND environment variable,
which behaves like GIT_SSH but is passed to the shell.
The special circuitry to modify parameters in the case of using
PuTTY's plink/tortoiseplink is activated only when using GIT_SSH;
in the case of using GIT_SSH_COMMAND, it is deliberately left up to
the user to make any required parameters adaptation before calling
the underlying ssh implementation.

"git help everyday" to show the Everyday Git document.
* po/everyday-doc:
doc: add 'everyday' to 'git help'
doc: Makefile regularise OBSOLETE_HTML list building
doc: modernise everyday.txt wording and format in man page style
The "Everyday GIT With 20 Commands Or So" is not accessible via the
Git help system. Move everyday.txt to giteveryday.txt so that "git
help everyday" works, and create a new placeholder file everyday.html
to refer people who follow existing URLs to the updated location.
giteveryday.txt now formats well with AsciiDoc as a man page and
refreshed content to a more command modern style.

In a config file, you can do:
[foo]
bar
to turn the "foo.bar" boolean flag on, and you can do:
[foo]
bar=
to set "foo.bar" to the empty string. However, git's "-c"
parameter treats both:
git -c foo.bar
and
git -c foo.bar=
as the boolean flag, and there is no way to set a variable
to the empty string. This patch enables the latter form to
do that.

trace: improve trace performance
trace: remove redundant printf format attribute
trace: consistently name the format parameter
trace: move trace declarations from cache.h to new trace.h
Use trace_performance to measure and print execution time and command line
arguments of the entire main() function. In constrast to the shell's 'time'
utility, which measures total time of the parent process, this logs all
involved git commands recursively. This is particularly useful to debug
performance issues of scripted commands (i.e. which git commands were
called with which parameters, and how long did they execute).
Due to git's deliberate use of exit(), the implementation uses an atexit
routine rather than just adding trace_performance_since() at the end of
main().
Usage example: > GIT_TRACE_PERFORMANCE=~/git-trace.log git stash list
Creates a log file like this:
23:57:38.638765 trace.c:405 performance: 0.000310107 s: git command: 'git' 'rev-parse' '--git-dir'
