Rikard Falkeborn afe05d019c dmake: Improve dependency detection of external and cli includes (#2163)
Previously, external files were not searched at all, and dependencies
on header files in cli was not taken into account for test files.

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

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.

Rikard Falkeborn 32eb6e1b19 donate-cpu: Only check libraries once (#2158)
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.

This fixes the issue by making `ProgramMemory` keep track of values based on the conditions.

It also removes the `deadpointer` check since it duplicates the `invalidLifetime` check.
