* Fix #9097 (Crash on thousands of "else ifs"s in gcc-avr package)

* increase recursion count maximum to 512 because cppcheck was hitting the 256 limit

* 512 was too much for windows

Rikard Falkeborn a1a14b8465 Fix FP with cast pointer to free() (#1961)
This fixes false positives when the pointer passed to free() (or similar
deallocation functions) is cast using a c-style cast.

Rikard Falkeborn 839fcddd8a Fix #6115 (Add support to realloc to cfg files) (#1953)
* Allow to configure realloc like functions

* memleakonrealloc: Bring back tests.

The old memleak checker was removed, and the tests for it was removed in
commit 9765a2dfab. This also removed the
tests for memleakOnRealloc. Bring back those tests, somewhat modified
since the checker no longer checks for memory leaks.

* Add realloc to mem leak check

* Add tests of realloc buffer size

* Configure realloc functions

* Add test of freopen

* Allow to configure which element is realloc argument

* Fix wrong close in test

cppcheck now warns for this

* Update manual

* Update docs

* Rename alloc/dalloc/realloc functions

Naming the member function realloc caused problems on appveyor. Rename
the alloc and dealloc functions as well for consistency.

* Change comparisson order

* Remove variable and use function call directly

* Create temporary variable to simplify

* Throw mismatchError on mismatching allocation/reallocation

* Refactor to separate function

* Fix potential nullptr dereference

As pointed out by cppcheck.

Rikard Falkeborn 60a213e6a5 Fix #9047 (c-style casts before malloc) (#1930)
* Fix #9047 (c-style casts before malloc)

Note that there are still no warnings for c++-style casts

* Fix memleak check with casts of assignments in if-statements

* Fix possible null pointer dereference

As pointed out by cppcheck.

* Add check of astOperand2 when removing casts

This is similar to how it is done in other checks.
