This topic branch introduces a highly-experimental feature allowing to
override stdin/stdout/stderr by setting environment variables e.g. to
named pipes, solving a problem in highly multi-threaded applications
where inheritable handles could cause blocked Git operations.

This feature is still highly experimental and has not even been
contributed to the Git mailing list yet: the feature still needs to be
battle-tested more.

Make use of the new environment variable GIT_ASK_YESNO to support the
recently implemented fallback in case unlink, rename or rmdir fail for
files in use on Windows. The added dialog will present a yes/no question
to the the user which will currently be used by the windows compat layer
to let the user retry a failed file operation.

The "2>&1" notation in POSIX shells implies that stderr is redirected to
stdout. Let's special-case this value for the environment variable
GIT_REDIRECT_STDERR to allow writing to the same destination as stdout.
The functionality was suggested by Jeff Hostetler.

It is better to state clearly expectations and intentions than to assume
quietly that everybody agrees.
This Code of Conduct is the Open Code of Conduct as per
http://todogroup.org/opencodeofconduct/ (the only modifications are the
adjustments to reflect that there is no "response team" in addition to the
Git for Windows maintainer, and the addition of the link to the Open Code
of Conduct itself).

On Windows, file handles need to be marked inheritable when they need to
be used as standard input/output/error handles for a newly spawned
process. The problem with that, of course, is that the "inheritable" flag
is global and therefore can wreak havoc with highly multi-threaded
applications: other spawned processes will *also* inherit those file
handles, despite having *other* input/output/error handles, and never
close the former handles because they do not know about them.
Let's introduce a set of environment variables (GIT_REDIRECT_STDIN and
friends) that point to files, or even better, named pipes and that are
used by the spawned Git process. This helps work around above-mentioned
issue: those named pipes will be opened in a non-inheritable way upon
startup, and no handles are passed around.

As v2.14.0 (final) is less than two weeks away, and as the most recent
"What's Cooking" mail has not indicated any maintenance release anytime
soon, let's prepare for v2.14.0 already now by rebasing onto v2.14.0-rc1,
so that https://wingit.blob.core.windows.net/files/index.html gets an
early preview.
A couple of patches had to be adjusted because the code changed in core
Git while the patches are still in flight.
While at it, the rebase-i-extra patch series has been updated to the most
recent iteration.
This commit starts the rebase of 0709ae1af8 to 418951619b

We started using "%" PRItime, imitating "%" PRIuMAX and friends, as
a way to format the internal timestamp value, but this does not
play well with gettext(1) i18n framework, and causes "make pot"

file. This is a possible workaround for that problem.

We started using our own timestamp_t type and PRItime format
specifier to go along with it, so that we can later change the
underlying type and output format more easily, but this does not
play well with gettext tools.
Because gettext tools need to keep the *.po file portable across
platforms, they have to special-case the format specifiers like
PRIuMAX that are known types in inttypes.h, instead of letting CPP
handle strings like
"%" PRIuMAX " seconds ago"
as an ordinary string concatenation. They fundamentally cannot do
the same for our own custom type/format.
Given that po/git.pot needs to be generated only once every release
and by only one person, i.e. the l10n coordinator, let's update the
Makefile rule to generate po/git.pot so that gettext tools are run
on a munged set of sources in which all mentions of PRItime are
replaced with PRIuMAX, which is what we happen to use right now.
This way, developers do not have to care that PRItime does not play
well with gettext, and translators do not have to care that we use
our own PRItime.
The credit for the idea to munge the source files goes to Dscho.
Possible bugs are mine.

The paragraph that describes the 'scissors' cleanup mode of
'commit' had the 'cut-line' in the middle of a sentence. This
made it possible for the line to get wrapped on smaler windows.
This shouldn't be the case as it makes it hard for the user to
understand the structure of the cut-line.
Reformat the pragraph to make the 'cut-line' stand on a line of
it's own thus distinguishing it from the rest of the paragraph.
This further prevents it from getting wrapped to some extent.

We run an early part of "git gc" that deals with refs before
daemonising (and not under lock) even when running a background
auto-gc, which caused multiple gc processes attempting to run the
early part at the same time. This is now prevented by running the
early part also under the GC lock.

On Cygwin, similar to Windows, "git push //server/share/repository"
ought to mean a repository on a network share that can be accessed
locally, but this did not work correctly due to stripping the double
slashes at the beginning.
This may need to be heavily tested before it gets unleashed to the
wild, as the change is at a fairly low-level code and would affect
not just the code to decide if the push destination is local. There
may be unexpected fallouts in the path normalization.

The i18n config variable used weren't readable as they were in
the crude form of how git stores/uses it's config variables.
Improve it's readability by replacing them with camelCased versions
of config variables as it doesn't have any impact on it's usage.

or until it gets EOF. But we never handle EOF in our loop,
and a short input will cause perl to go into an infinite
