Rikard Falkeborn 8cd1d5a47d Use library for memleak checks (#2002) 
* Use library for memleak checks

Change memleakOnRealloc and leakReturnValNotUsed to use library
configuration instead of hardcoding "realloc".

In order to do so, some care needs to be taken when matching for a
reallocation function, since it can no longer be assumed that the input
to be allocated is the first argument of the function. This complicates
getReallocationType() and checkReallocUsage() but is necessary in order
to handle for example freopen() properly.

Also, refactor memleakOnRealloc check to reduce duplicated code when
checking "a" and "*a". When doing so, extending the check to look for
arbitrary number of "*" can be done for free (just change an if
statement to a while statement). Most likely, this is an unusual case in
real world code.

* Remove redundant whitespace in Token::Match()

* Run on simplified checks

* Fix cppcheck warning

Rikard Falkeborn abea580b78 Fix FP memory leak with unknown function call in condition (#2012) 
* Fix FP memory leak with unknown function call in condition

This was introduced in 8513fb81d2 when
fixing memory leaks for global variables allocated in condition. The
refactored code had an inconsistency where c and c++ code behaved
slightly differently when `var` is NULL. This seemed to not have an
impact as the code was written prior to 8513fb81d2,
but when the same code was used for conditions, FPs were introduced.

The introduced FPs were memleak warnings when there should have been an
information message about missing configurations for code like

	void f() {
		char *p = malloc(10);
		if (set_data(p)) {}
	}

Fix this by always returning true if varTok->Variable() is NULL for
both c and c++ code.

* Improve function name
