Daniel Marjamäki cf79830afd Revert "Remove bailout. It hides lots of warnings for real code to avoid FP in unused templates." 
This reverts commit 2a4be5ae1c.

When I look at daca@home now there are still lots of false negatives. So this bailout did not cause as much false negatives as I thought.

Rikard Falkeborn d909ac8565 Bugfix buffer size for strdup like functions (#1893) 
strdup() allocates the string length plus one for a terminating null
character. Add one to compensate for this.

Fixes false positive buffer out of bounds on code like this:

	void f() {
		const char *a = "abcd";
		char * b = strdup(a);
		printf("%c", b[4]); // prints the terminating null character
		free(b);
	}

Also, add a testcase for valueFlowDynamicBufferSize() and add tests for
strdup(), malloc() and calloc().

IOBYTE 75720528b0 template simplifier: add 2 new template parameter simplifications (#1884) 
* template simplifier: add 2 new template parameter simplifications

int{} -> 0
decltype(int{}) -> int

This fixes reduced test cases like #9153.  I'm not sure they will help
real world code that much.

It was necessary to increase the pass count to 4 to get #9153 completly
simplified.

* relax decltype(type{}) simplification to any type
