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.

John Marshall 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

Sebastian fd900ab8b2 testnullpointer.cpp: Add test for dereferencing returned NULL pointer (#2401)
This adds a regression test to make sure that directly dereferencing a
returned NULL pointer issues a warning.
This has been asked on Stack Overflow:
https://stackoverflow.com/q/58981369
Cppcheck 1.89 does not warn for such a code, but 1.90 dev does. So it
is a good idea to make sure it is detected in the future too I guess.
