The way the OSX build jobs updates its build environment used the
"--quiet" option to "brew update" command, but it wasn't all that
quiet to be useful. The use of the option has been replaced with
an explicit redirection to the /dev/null (which incidentally would
have worked around a breakage by recent updates to homebrew, which
has fixed itself already).

Before installing the necessary dependencies, our OSX build jobs run
'brew update --quiet'. This is problematic for two reasons:
- This '--quiet' flag apparently broke overnight, resulting in
errored builds:
+brew update --quiet

Usage: brew update_report [--preinstall]
The Ruby implementation of brew update. Never called manually.
--preinstall Run in 'auto-update' mode (faster, less
output).
-f, --force Override warnings and enable potentially
unsafe operations.
-d, --debug Display any debugging information.
-v, --verbose Make some output more verbose.
-h, --help Show this message.
Error: invalid option: --quiet
The command "ci/install-dependencies.sh" failed and exited with 1 during .
I belive that this breakage will be noticed and fixed soon-ish, so
we could probably just wait a bit for this issue to solve itself,
but:
- 'brew update --quiet' wasn't really quiet in the first place, as
it listed over about 2000 lines worth of available packages that
we absolutely don't care about, see e.g. one of the latest
'master' builds:
https://travis-ci.org/git/git/jobs/486134962#L113
So drop this '--quiet' option and redirect 'brew update's standard
output to /dev/null to make it really quiet, thereby making the OSX
builds work again despite the above mentioned breakage.

The upcoming patches will allow building git.git via Azure Pipelines
(i.e. Azure DevOps' Continuous Integration), where variable names and
URLs look a bit different than in Travis CI.
Also, the configurations of the available agents are different. For
example, Travis' and Azure Pipelines' macOS agents are set up
differently, so that on Travis, we have to install the git-lfs and
gettext Homebrew packages, and on Azure Pipelines we do not need to.
Likewise, Azure Pipelines' Ubuntu agents already have asciidoctor
installed.
Finally, on Azure Pipelines the natural way is not to base64-encode tar
files of the trash directories of failed tests, but to publish build
artifacts instead. Therefore, that code to log those base64-encoded tar
files is guarded to be Travis-specific.

The name is hard-coded to reflect that we use Travis CI for continuous
testing.
In the next commits, we will extend this to be able use Azure DevOps,
too.
So let's adjust the name to make it more generic.

Our 'Makefile' hardcodes the compiler to build Git as 'CC = cc'. This
CC variable can be overridden from the command line, i.e. 'make
CC=gcc-X.Y' will build with that particular GCC version, but not from
the environment, i.e. 'CC=gcc-X.Y make' will still build with whatever
'cc' happens to be on the platform.
Our build jobs on Travis CI are badly affected by this. In the build
matrix we have dedicated build jobs to build Git with GCC and Clang
both on Linux and macOS from the very beginning (522354d70f (Add
Travis CI support, 2015-11-27)). Alas, this never really worked as
supposed to, because Travis CI specifies the compiler for those build
jobs as 'export CC=gcc' and 'export CC=clang' (which works fine for
projects built with './configure && make'). Consequently, our
'linux-clang' build job has always used GCC, because that's where 'cc'
points at in Travis CI's Linux images, while the 'osx-gcc' build job
has always used Clang. Furthermore, 37fa4b3c78 (travis-ci: run gcc-8
on linux-gcc jobs, 2018-05-19) added an 'export CC=gcc-8' in an
attempt to build with a more modern compiler, but to no avail.
Set MAKEFLAGS with CC based on the $CC environment variable, so 'make'
will run the "right" compiler. The Xcode 10.1 macOS image on Travis
CI already contains the gcc@8 package from Homebrew, but we have to
'brew link' it first to be able to use it.
So with this patch our build jobs will build Git with the following
compiler versions:
linux-clang: clang version 5.0.0 (tags/RELEASE_500/final)
linux-gcc: gcc-8 (Ubuntu 8.1.0-5ubuntu1~14.04) 8.1.0
osx-clang: Apple LLVM version 10.0.0 (clang-1000.11.45.5)
osx-gcc: gcc-8 (Homebrew GCC 8.2.0) 8.2.0
GETTEXT_POISON: gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

Ever since we started using Travis CI, we specified the list of
packages to install in '.travis.yml' via the APT addon. While running
our builds on Travis CI's container-based infrastructure we didn't
have another choice, because that environment didn't support 'sudo',
and thus we didn't have permission to install packages ourselves. With
the switch to the VM-based infrastructure in the previous patch we do
get a working 'sudo', so we can install packages by running 'sudo
apt-get -y install ...' as well.
Let's make use of this and install necessary packages in
'ci/install-dependencies.sh', so all the dependencies (i.e. both
packages and "non-packages" (P4 and Git-LFS)) are handled in the same
file. Install gcc-8 only in the 'linux-gcc' build job; so far it has
been unnecessarily installed in the 'linux-clang' build job as well.
Print the versions of P4 and Git-LFS conditionally, i.e. only when
they have been installed; with this change even the static analysis
and documentation build jobs start using 'ci/install-dependencies.sh'
to install packages, and neither of these two build jobs depend on and
thus install those.
This change will presumably be beneficial for the upcoming Azure
Pipelines integration [1]: preliminary versions of that patch series
run a couple of 'apt-get' commands to install the necessary packages
before running 'ci/install-dependencies.sh', but with this patch it
will be sufficient to run only 'ci/install-dependencies.sh'.

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'.)

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.

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
code into dedicated scripts and make them call the library first.
