fix crash while checking misra_9 when initializing a union with {{0,0}} (#5250)
This fixes a crash with following error:

            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'getChildByValueElement'
```

A minimal example and testcase is added. 
The extra check for nextChild seems to fix it, however i did not read
the whole codebase, so maybe this creates other issues.

donate-cpu: greatly improved `LibraryIncludes.get_libraries()` performance / some optimizations and cleanups (#4273)
* donate_cpu_lib.py: use `os.path.join()`

* donate-cpu: removed remaining usage of `os.chdir()`

* donate_cpu_lib.py: moved library includes code into class

* donate_cpu_lib.py: pre-compile library include regular expressions

* donate_cpu_lib.py: pre-compile some more regular expressions

* donate_cpu_lib.py: small unpack_package() cleanup and optimization

* donate_cpu_lib.py: added some information about the extracted files to unpack_package()

* donate_cpu_lib.py: bumped version

* added test_donate_cpu_lib.py

* donate_cpu_lib.py: greatly improved `LibraryIncludes.get_libraries()` performance

only scan each file once for previously undetected libraries only

* test_donate_cpu_lib.py: fix for Python 3.5

* scriptcheck.yml: added `-v` to pytest calls so we get the complete diff on assertions

* fixed `test_arguments_regression()` Python tests with additional pytest arguments

* donate_cpu_lib.py: use `subprocess.check_call()`

* test_donate_cpu_lib.py: sort results to address differences in order with Python 3.5

Richard A. Smith 2b44fb57bc Loosen restrictions on MISRA rules text structure (#2157)
Version 1.88 changed the parsing of the MISRA rules file adding a
severity setting.  This caused a regression in rule parsing.

In particular the following format used to parse cleanly and produce
rule output that would show the severity as part of the rule text.

    Rule 1.2

    Advisory

    Rule text goes here.

    Rule 1.3

    Required

    More rule text goes here.

As of 1.88 a file structured like above would parse as having no rules.

The problem is the use of blank lines as a rule delimiter.   The
modified rule parser wants to see a rules formatted like below:

    Rule 3.1 Required
    R3.1 text.
    Rule 4.1 Required
    R4.1 text.

or:

    Rule 1.1
    Add this rule and parse to next, skipping empty lines.

    Rule 1.2
    Rule text.

Any rule text that did not fall into one of the above formats would
result in incomplete rule text parsing.

Change the parsing of the rule text file so that blank lines are ignored
instead of treating them as a delimiter between rules. Instead use the
start of the next rule as a delimiter for the end of the previous rule.
This allows both of the newer formats but also supports the behavior of
pre-1.88 versions.

Change units tests that were specifically forbidding the use of blank
lines to ones that allow blank lines.
