Fix #9299 (Makefile: tools/matchcompiler.py is executed via Python 2) (#2247)
Check if "python" is available, if not check for "python3" and use
the available Python interpreter. If no Python interpreter is found,
"make" fails with an according error message.
This solves the issue that not all modern Linux distributions any longer
install Python 2 by default, so "python" is not available and
"make MATCHCOMPILER=yes" would fail. Instead of forcing the users to
install Python 2, Python 3 is used in such a case now if it is
available.

Sebastian bfbfeefbb3 reduce.py: Allow reducing error messages, print output in case of error (#2179)
* reduce.py: Allow reducing error messages, print output in case of error

Allow reducing code that triggers (false positive) error messages.
Print Cppcheck output in case Cppcheck returns unsuccessfully and no
segfault is expected. This helps fixing messed up command lines (for
example issues with the path).

* Use "else" as suggested

donate-cpu.py: Add internal timing information of Cppcheck to output (#2217)
* donate-cpu.py: Add internal timing information of Cppcheck to output

The option "--showtime=top5" is added to the Cppcheck command line.
The timing output is collected and only for HEAD it is shown in the new
category "head-timing-info" in the results output.
The timing output is indented with one white space, so even in the
unlikely case that a function is named "head result:" or "diff:" it does
not break the parser in the server.

* donate-cpu.py: Also print the "old" timing information for comparison

Sebastian fe236dbdc4 donate-cpu.py: Improve Qt library detection (#2171)
Some projects only use this (older?) style of Qt header inclusion.
There are (older) books and examples which use this style, too.
It seems to be perfectly valid, so we should support it.

Rikard Falkeborn afe05d019c dmake: Improve dependency detection of external and cli includes (#2163)
Previously, external files were not searched at all, and dependencies

To add dependency of headers in externals, we also need to search for
includes with angular brackets.

There is no point in checking which libraries to use for each cppcheck
version since there is no change. Refactor the checking to a separate
function and run that once instead. This halves the time it takes to
check for libraries.

Rikard Falkeborn 0324bbf63c dmake: Fix check of last header file in lib.pri (#2045)
Since the number of test files is larger than the number of lib files,
this only caused an extra harmless '\' being printed after the last
header file in lib.pri. If the number of test files would have been
smaller than the number of lib files, the generated lib.pri would have
been broken.

.travis.yml: Check more Python scripts with pylint (#2019)
Use renamed pylintrc file that is only meant for Travis checks.

Check all Python scripts in 'addons', 'htmlreport' and 'tools'

Errors for `_socketobject` class are disabled, see
https://stackoverflow.com/questions/10300082/how-to-prevent-python-pylint-complaining-about-socket-class-sendall-method

Install imported modules `unittest2` and `pexpect` via pip.

Add "./addons" to search-path for modules because
"tools/compare-ast-clang-and-cppcheck.py" imports cppcheckdata.py from
addons. Pylint does not seem to evaluate
`sys.path.insert(0, '../addons')` in the script. So an `init-hook` is
necessary in pylintrc_travis.

Scott Furry e459762bcd Suppress Code semantic and syntax warnings (#1936)
Sources were built with Clang but with increased verbosity of error detection.

A number of syntax and semantic warnings were encountered. Commit adds
changes to correct these warnings.

Some changes involve removing extra, and unncessary, semi-colons at EOL
(e.g. at end of switch clause).

Project astyle settings are not currently setup to detect if a file is to
have an extra carriage return after the last line of data. Two files were
altered to ensure an extra carriage return.

An advisory to enhance code was encountered in triage code. Clang advisory
on a for-loop interation value suggested that:
`use reference type 'const QString &' to prevent copying`

address CodeEditor style usage in triage app at this time.

Code Editor style can be altered from the added "Code Editor"
tab in the user preferences. The user has the option to select
default light, default dark, or to customize.

If user leaves the style set to light or dark defaults, this
will be reflected in the choices shown in the preferences
dialog.

User choice for Code Editor Style is saved in the cppcheck-gui
preferences under the heading "EditorStyle".

donate-cpu.py: Add new argument `--max-packages=N`. (#1718)
The client script will exit after the specified number of packages
have been processed. 0 means infinitely.
Useful for example to regularly quit the script, check for updates to
the client and start it again. Or as an alternative to the `--stop-time`
argument.

versat e64fc279f0 donate-cpu-server.py: Format total times like the package times.
Without formatting it could happen sometimes that the time is printed
like this: 245.099999999, now only one digit after the decimal point
is shown.

donate-cpu-server.py: Replace syntax that is deprecated in Python 3. (#1712)
The function `iteritems()` of `dict`s is deprecated. The recommended
alternative is to use `items()`, this function also works with Python 2.

The next issue is that lambdas can no longer unpack tuple parameters
in Python 3. It would be possible to use some workaround and still use
a lambda, but using `operator.itemgetter(1)` instead is faster and the
recommended method in such a case.

The syntax is now compatible with Python 2 and 3 but the server script
still does not work with Python 3. For example `socket.recv()` returns
`bytes` in Python 3 and `str` in Python 2. Currently `str` is expected
so it does not work with Python 3.
