Fix false negatives for local suppressions

Introduce a new bool setting jointSuppressionReport
that will be set by the analyseWholeProgram() code path.
When the flag is enabled, unmatched suppressions are
collected after running the final whole program analysis
to prevent false positives for the unusedFunction check.
The check functions in the unit test
for single / multi file suppressions were unified.

Fix segfault in template simplifier
...
When something parsing the template syntax
went wrong, "tok2" was NULL and resulted
in deleting all remaining tokens. Whoops.
Triggered by gcc test suite:
gcc/testsuite/g++.dg/cpp0x/variadic87.C
Tracked down the source of the bug with
valgrind's "--track-origins=yes" switch.

Add new "style" check to catch redundant pointer operations
...
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".
The new check is fully AST based and was given
strong false positive testing on a large code base.

Verbose AST dump: Show if token is expanded from macro

Use unsigned int for all flags
...
Frank Zingsheim reported: With the parameter 'flag_'
and the member variable '_flags' having the type 'int'
produces a lot of warings in clang:
"warning: implicit conversion changes signedness: 'int' to 'unsigned int'".

Add bounds check to getVariableFromVarId()

While poking around the memory leak check,
I managed to trigger an out-of-bounds access
in the symbol database.
Fix it by sanity checking the variable id
passed to getVariableFromVarId().

- Avoid leaving and entering again critical section without doing anything
- Use isPointer() in checkbufferoverrun.cpp instead of string comparison
