`--html-nested` was added to gcovr in version 6.0 so passing
it to versions before this will result in gcovr complaining that
it doesn't recognise the argument.
Added a version check to ensure that we pass a recognised argument
for versions before 6.0

The documentation for subprocess.run at https://docs.python.org/3/library/subprocess.html#popen-constructor has a warning,
pointing to using shutil.which() instead of subprocess.run for detecting if exe files exists on the path.
shutil.which() is used in many places already.
--html-nested option is used to create a separate web page for each file and directory. Each of these web pages includes the contents of file with annotations that summarize code coverage.

The .lcovrc file can contain several directives for genhtml, mostly
pertaining the visualisation of the generated HTML report. Passing the
config file to genhtml allows the user to customize their report.
Fixes#12863
This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
Version 2.0 of lcov triggers an error when an exclude pattern is unused. This
can happen when the project has subprojects, but no code in them ends up
covered:
lcov: ERROR: 'exclude' pattern '/[...]/subprojects/*' is unused.
(use "lcov --ignore-errors unused ..." to bypass this error)
So, simply do as it says. Unused patterns doesn't seem problematic (or even
interesting) here, so I don't think there's any risk in simply turning this
off, which matches what happened with earlier versions of lcov anyway.
lcov 2.0 deprecates `--rc lcov_branch_coverage=1` for `--rc branch_coverage=1` and
gives an error when an exclude is used on a non existing directory.
I added a version check for lcov and removed the subprojects directory from the
exclusion list if it does not exist.
Fixes#11995
gcovr will read this file anyway, but if it exists we don't need to
assume that the project wishes to exclude subprojects/ -- they can
determine that themselves.
Fixes#3287Closes#9761
lcov doesn't read the config file by default, but we can do the smart
thing here.

We say:
> If version 4.2 or higher of the first is found, targets coverage-text,
> coverage-xml, coverage-sonarqube and coverage-html are generated.
But this is totally untrue. Make it true, by actually checking (and
not generating broken coverage commands when older versions of gcovr are
found).
Fixes#9505
Sonarcloud.io only can read the sonarqube based report that gcovr can
produce. This change enables support for this output in meson and
ninja.

D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
The out-of-source build syntax for gcovr 4.2 is different compared to
previous versions and therefore an update was needed. In researching the
most appropriate solution it was found that any gcovr version older than
3.3 always resulted in 0% coverage. Because of this, rather than adding
an additional layer of logic, some already existing logic was modified
to ensure correct syntax for the new version, while versions older than
3.3 are flagged as not supported.
Closes mesonbuild#5089.
The code our projects care about verifying coverage for mostly lives in
the source_root with the exception of the generated source files in
build_root. This change cleans up the output so we don't have prefixed
paths on our source files anymore.
summary from stdout is often used by Automated builds to show build details
The --print-summary option was added to gcovr in v3.2, since html output
was added only in 3.1, limitting support to 3.2 won’t be a big deal.
--print-summary is not enabled for text/xml report generation as it will
result in meson not supporting any gcovr version less than 3.2.
Restore subproject exclusion for the html coverage report that existed
in the ninja backend legacy target.
Also exclude subprojects for the gcovr generated reports.
ninja coverage -> generate all possible reports (text, xml, html)
depending on gcovr and/or lcov/genhtml availability.
ninja coverage-html -> generate only html report
ninja coverage-xml -> generate only xml report
ninja coverage-text -> generate only text report
Make all targets phony, the old legacy rules where just annoying as
you would have to remove the old report before being able to generate
a new one.
ninja coverage succeeds if it can generate at least one report.
ninja coverage-* only succeeds if it can generate the requested report
Modern gcovr includes html generation support so if lcov and
genhtml are not available fallback to gcovr.
Kept lcov and genhtml as default so to not surprise existing
users of coverage-html with the different output of gcovr.
gcovr added html support in 3.0 but as there already is a test
for 3.1 because of the changes to -r/--rootdir I opted to only
allow html generation for >= 3.1 to keep things simple.
In gcovr 3.1 the -r/--rootdir argument changed meaning causing
reports generated with gcovr 3.1 to not find the source files
and look for *.gcda in the whole source tree rather than the
build dir.
So, detect gcovr version and if 3.1 give build_root to -r instead
of source_root.
Cuurently, a set of directories is filtered out from the output based on
the location of system includes on most common linux distro's. This
commit does away with the blacklist and implements a whitelist approach:
only the files inside the source root are shown.
