misra: Fixed crash with struct fields with unknown types on 9.x rules (#3305)
This fixes the crash on with struct fields containing unknown types
reported on the forum:
https://sourceforge.net/p/cppcheck/discussion/general/thread/d64551cc55/#5f0f

The suggested patch doesn't handle the cases when there are struct
fields with arrays containing unknown types. So the addon will not
generate warnings in these cases. The problem is that Cppcheck doesn't
generate valueType-pointer information for unknown types in the dump
file. When adding this in symboldatabase.cpp, MISRA addon will generate
a lot of false positives because we depend on the null value of
valueType.

So I suppose it better to left this as is, to don't break the addon for
such rare cases.

misra: Add support for expected suppressions in header files in `-verify` mode (#3252)
This commit allows to specify expected suppressions in the included
header files. This is necessary to verify MISRA checkers, which make
requirements for header files. For example, Rule 8.2 requires adding
prototypes for each function to the header files.

misra: Fixed a crash in rule 8.2 (#3208)
Due to incorrect indentation, we return "None" instead of an empty list,
which causes the crash.

misra.py: Treat enum constants as constant known at compile time (#2823)
C89 standard defines enum members as enumeration contants at ch.
6.4.4.3, and they are always known at compile time.

This commit fix false positives for rule 18.8 (and possible other rules
that check "constentess") with enumeration members.
