errorlogger.cpp: Handle empty file-name like "*" (unmatchedSuppression) (#2440) 
Using "--suppress=unmatchedSuppression" did not suppress the error-id in
all files, one needed to specify "*" as file-name. This commit also
allows empty file-names to suppress "unmatchedSuppression", not only "*"
or the exact file-name.
The manual uses the following example for suppressions specified in a
file:
// suppress all uninitvar errors in all files
uninitvar

This example suggests that no "*" has to be used to get suppression in
all files. I think that the command line parameter should work in the
same way.

Catch preprocessor errors possibly issued during loading files (#2430) 
* Also catch preprocessor errors possibly issued during loading files

Currently only errors that are issued during preprocessing are caught.

* Bump simplecpp, implement suggestions

Use return value checking instead of catching an exception for calling
Preprocessor::loadFiles().
Handle new enum value simplecpp::Output::EXPLICIT_INCLUDE_NOT_FOUND
where the corresponding enum is used in Cppcheck.

* Use "noloc" location if an explicit include can not be opened

297efcd049 Avoid some additional memleakOnRealloc false positives (#2422) 
* Avoid some additional memleakOnRealloc false positives

checkReallocUsage() already contains code to suppress the
`p = realloc(p, size)` error message when the pointer has been
previously copied from another variable (hence there is an additional
copy of the original pointer value) within the same function, as in
the added realloc21() test case.

Extend this so that `p = *pp` and `p = ptr->foo` are also recognized
as copies from another variable with the same original pointer value,
as in the added realloc22() and realloc23() test cases.

* Rewrite as a single findmatch() expression
