While the build logic was embedded in our '.travis.yml', Travis CI
used to produce a nice trace log including all commands executed in
those embedded scriptlets. Since 657343a60 (travis-ci: move Travis CI
code into dedicated scripts, 2017-09-10), however, we only see the
name of the dedicated scripts, but not what those scripts are actually
doing, resulting in a less useful trace log. A patch later in this
series will move setting environment variables from '.travis.yml' to
the 'ci/*' scripts, so not even those will be included in the trace
log.
Use 'set -x' in 'ci/lib-travisci.sh', which is sourced in most other
'ci/*' scripts, so we get trace log about the commands executed in all
of those scripts.

Commit 657343a60 (travis-ci: move Travis CI code into dedicated
scripts, 2017-09-10) converted '.travis.yml's default 'before_install'
scriptlet to the 'ci/install-dependencies.sh' script, and while doing
so moved setting GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang
Linux build jobs to that script. This is wrong for two reasons:
- The purpose of that script is, as its name suggests, to install
dependencies, not to set any environment variables influencing
which tests should be run (though, arguably, this was already an
issue with the original 'before_install' scriptlet).
- Setting the variable has no effect anymore, because that script is
run in a separate shell process, and the variable won't be visible
in any of the other scripts, notably in 'ci/run-tests.sh'
responsible for, well, running the tests.
Luckily, this didn't have a negative effect on our Travis CI build
jobs, because GIT_TEST_HTTPD is a tri-state variable defaulting to
"auto" and a functioning web server was installed in those Linux build
jobs, so the httpd tests were run anyway.
Apparently the httpd tests run just fine without GIT_TEST_HTTPD being
set, therefore we could simply remove this environment variable.
However, if a bug were to creep in to change the Travis CI build
environment to run the tests as root or to not install Apache, then
the httpd tests would be skipped and the build job would still
succeed. We would only notice if someone actually were to look
through the build job's trace log; but who would look at the trace log
of a successful build job?!
Since httpd tests are important, we do want to run them and we want to
be loudly reminded if they can't be run. Therefore, move setting
GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang Linux build jobs
to 'ci/lib-travisci.sh' to ensure that the build job fails when the
httpd tests can't be run. (We could set it in 'ci/run-tests.sh' just
as well, but it's better to keep all environment variables in one
place in 'ci/lib-travisci.sh'.)

Our '.travis.yml's 'env.global' section sets a bunch of environment
variables for all build jobs, though none of them actually affects all
build jobs. It's convenient for us, and in most cases it works just
fine, because irrelevant environment variables are simply ignored.
However, $GIT_SKIP_TESTS is an exception: it tells the test harness to
skip the two test scripts that are prone to occasional failures on
OSX, but as it's set for all build jobs those tests are not run in any
of the build jobs that are capable to run them reliably, either.
Therefore $GIT_SKIP_TESTS should only be set in the OSX build jobs,
but those build jobs are included in the build matrix implicitly (i.e.
by combining the matrix keys 'os' and 'compiler'), and there is no way
to set an environment variable only for a subset of those implicit
build jobs. (Unless we were to add new scriptlets to '.travis.yml',
which is exactly the opposite direction that we took with commit
657343a60 (travis-ci: move Travis CI code into dedicated scripts,
2017-09-10)).
So move setting $GIT_SKIP_TESTS to 'ci/lib-travisci.sh', where it can
trivially be set only for the OSX build jobs.
Furthermore, move setting all other environment variables from
'.travis.yml' to 'ci/lib-travisci.sh', too, because a couple of
environment variables are already set there, and this way all
environment variables will be set in the same place. All the logic
controlling our builds is already in the 'ci/*' scripts anyway, so
there is really no good reason to keep the environment variables
separately.

A couple of 'ci/*' scripts are shared between different build jobs:
'ci/lib-travisci.sh', being a common library, is sourced from almost
every script, while 'ci/install-dependencies.sh', 'ci/run-build.sh'
and 'ci/run-tests.sh' are shared between the "regular" GCC and Clang
Linux and OSX build jobs, and the latter two scripts are used in the
GETTEXT_POISON Linux build job as well.
Our builds could benefit from these shared scripts being able to
easily tell which build job they are taking part in. Now, it's
already quite easy to tell apart Linux vs OSX and GCC vs Clang build
jobs, but it gets trickier with all the additional Linux-based build
jobs included explicitly in the build matrix.
Unfortunately, Travis CI doesn't provide much help in this regard.
The closest we've got is the $TRAVIS_JOB_NUMBER variable, the value of
which is two dot-separated integers, where the second integer
indicates a particular build job. While it would be possible to use
that second number to identify the build job in our shared scripts, it
doesn't seem like a good idea to rely on that:
- Though the build job numbering sequence seems to be stable so far,
Travis CI's documentation doesn't explicitly states that it is
indeed stable and will remain so in the future. And even if it
were stable,
- if we were to remove or insert a build job in the middle, then the
job numbers of all subsequent build jobs would change accordingly.
So roll our own means of simple build job identification and introduce
the $jobname environment variable in our builds, setting it in the
environments of the explicitly included jobs in '.travis.yml', while
constructing one in 'ci/lib-travisci.sh' as the combination of the OS
and compiler name for the GCC and Clang Linux and OSX build jobs. Use
$jobname instead of $TRAVIS_OS_NAME in scripts taking different
actions based on the OS and build job (when installing P4 and Git LFS
dependencies and including them in $PATH). The following two patches
will also rely on $jobname.

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.

If we push a branch and a tag pointing to the HEAD of this branch,
then Travis CI would run the build twice. This wastes resources and
slows the testing.

if appropriate. Invoke this function on every build.

Most of the Travis CI commands are in the '.travis.yml'. The yml format
does not support functions and therefore code duplication is necessary
to run commands across all builds.
To fix this, add a library for common CI functions. Move all Travis CI

`make` does not necessarily fail with an error code if
Asciidoc/AsciiDoctor encounters problems. Anything written to stderr
might be a better indicator for problems.
Ensure that nothing is written to stderr during a documentation build.
The redirects do not work in `sh`, therefore the script uses `bash`.
This shouldn't be a problem as the script is only executed on TravisCI.

Most Git developers work on Linux and they have no way to know if their
changes would break the Git for Windows build. Let's fix that by adding
a job to TravisCI that builds and tests Git on Windows. Unfortunately,
TravisCI does not support Windows.
Therefore, we did the following:
* Johannes Schindelin set up a Visual Studio Team Services build
sponsored by Microsoft and made it accessible via an Azure Function
that speaks a super-simple API. We made TravisCI use this API to
trigger a build, wait until its completion, and print the build and
test results.
* A Windows build and test run takes up to 3h and TravisCI has a timeout
after 50min for Open Source projects. Since the TravisCI job does not
use heavy CPU/memory/etc. resources, the friendly TravisCI folks
extended the job timeout for git/git to 3h.
Things, that would need to be done:
* Someone with write access to https://travis-ci.org/git/git would need
to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI
repository setting [1]. Afterwards the build should just work.
Things, that might need to be done:
* The Windows box can only process a single build at a time. A second
Windows build would need to wait until the first finishes. This
waiting time and the build time after the wait could exceed the 3h
threshold. If this is a problem, then it is likely to happen every day
as usually multiple branches are pushed at the same time (pu/next/
master/maint). I cannot test this as my TravisCI account has the 50min
timeout. One solution could be to limit the number of concurrent
TravisCI jobs [2].

When Git v2.9.1 was released, it had a bug that showed only on Windows
and on 32-bit systems: our assumption that `unsigned long` can hold
64-bit values turned out to be wrong.
This could have been caught earlier if we had a Continuous Testing
set up that includes a build and test run on 32-bit Linux.
Let's do this (and take care of the Windows build later). This patch
asks Travis CI to install a Docker image with 32-bit libraries and then
goes on to build and test Git using this 32-bit setup.
