The constants used for `ref_update::flags` were rather disorganized:
* The definitions in `refs.h` were not close to the functions that
used them.
* Maybe constants were defined in `refs-internal.h`, making them
visible to the whole refs module, when in fact they only made sense
for the files backend.
* Their documentation wasn't very consistent and partly still referred
to sha1s rather than oids.
* The numerical values followed no rational scheme
Fix all of these problems. The main functional improvement is that
some constants' visibility is now limited to `files-backend.c`.

`prune_ref()` needs to use the `REF_ISPRUNING` flag, but we want to
make that flag private to the files backend. So instead of calling
`ref_transaction_delete()`, which is a public function and therefore
shouldn't allow the `REF_ISPRUNING` flag, change `prune_ref()` to call
`ref_transaction_add_update()`, which is private to the refs
module. (Note that we don't need any of the other services provided by
`ref_transaction_delete()`.)
This allows us to change `ref_transaction_update()` to reject the
`REF_ISPRUNING` flag. Do so by adjusting
`REF_TRANSACTION_UPDATE_ALLOWED_FLAGS`. Also add parentheses to its
definition to avoid potential future mishaps.

The files backend uses `ref_update::flags` for several internal flags.
But those flags have no meaning to the packed backend. So when adding
updates for the packed-refs transaction, only use flags that make
sense to the packed backend.
`REF_NODEREF` is part of the public interface, and it's logically what
we want, so include it. In fact it is actually ignored by the packed
backend (which doesn't support symbolic references), but that's its
own business.

After we have sorted the `cnt`-many commits that we have selected, we
place them into the commit list. We then set `p->next` to NULL, but as
we do so, `p` is already pointing one beyond item number `cnt`. Indeed,
we check whether `p` is NULL before dereferencing it.
This only matters if there are TREESAME-commits. Since they should be
skipped, they are not included in `cnt` and we will hit the situation
where we set `p->next` to NULL. As a result, the list will be one longer
than it should be. The last commit in the list will be one which occurs
earlier, or which shouldn't be included.
Do not update `p` the very last round in the loop. This ensures that
after the loop, `p->next` points to the remainder of the list, and we
can set it to NULL. While we're here, free that remainder to fix a
memory leak.

This function takes a commit list and returns a commit list. The

should not use the original list again (and after the next commit fixes
a memory leak, it must not).

return type. That should make it harder to misuse this function.

Andrew Baumann reported that when called outside of any Git worktree,
`git rev-parse --is-inside-work-tree` eventually tries to access
`//HEAD`, i.e. any `HEAD` file in the root directory, but with a double
slash.
This double slash is not only unintentional, but is allowed by the POSIX
standard to have a special meaning. And most notably on Windows, it
does, where it refers to a UNC path of the form `//server/share/`.
As a consequence, afore-mentioned `rev-parse` call not only looks for
the wrong thing, but it also causes serious delays, as Windows will try
to access a server called `HEAD`. Let's simply avoid the unintended
double slash.

Particularly when calling Git from applications, such as Visual Studio's
Team Explorer, it is important that stdin/stdout/stderr are closed
properly. However, when spawning processes on Windows, those handles
must be marked as inheritable if we want to use them, but that flag is a
global flag and may very well be used by other spawned processes which
then do not know to close those handles.
Let's introduce a set of environment variables (GIT_REDIRECT_STDIN and
friends) that specify paths to files, or even better, named pipes (which
are similar to Unix sockets) 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 (and therefore no inherited handles need to be
closed by any spawned child).
This feature shipped with Git for Windows (marked as experimental) since
v2.11.0(2), so it has seen some serious testing in the meantime.

Linux build jobs on Travis CI skip the P4 and Git LFS tests since
commit 657343a60 (travis-ci: move Travis CI code into dedicated
scripts, 2017-09-10), claiming there are no P4 or Git LFS installed.
The reason is that P4 and Git LFS binaries are not installed to a
directory in the default $PATH, but their directories are prepended to
$PATH. This worked just fine before said commit, because $PATH was
set in a scriptlet embedded in our '.travis.yml', thus its new value
was visible during the rest of the build job. However, after these
embedded scriptlets were moved into dedicated scripts executed in
separate shell processes, any variable set in one of those scripts is
only visible in that single script but not in any of the others. In
this case, 'ci/install-dependencies.sh' downloads P4 and Git LFS and
modifies $PATH, but to no effect, because 'ci/run-tests.sh' only sees
Travis CI's default $PATH.
Move adjusting $PATH to 'ci/lib-travisci.sh', which is sourced in all
other 'ci/' scripts, so all those scripts will see the updated $PATH
value.

When we replaced the old shell script based interactive rebase in
commmit 18633e1a22 ("rebase -i: use the rebase--helper builtin",
2017-02-09) we introduced a regression of functionality in that the
GIT_DIR would be sent to the environment of the exec command as-is.
This generally meant that it would be passed as "GIT_DIR=.git", which
causes problems for any exec command that wants to run git commands in
a subdirectory.
This isn't a very large regression, since it is not that likely that the
exec command will run a git command, and even less likely that it will
need to do so in a subdir. This regression was discovered by a build
system which uses git-describe to find the current version of the build
system, and happened to do so from the src/ sub directory of the
project.
Fix this by passing in the absolute path of the git directory into the
child environment.
