Fixed #1132 (Detection of misused scope objects)
...
Emits error in the form:
[useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately
...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.
Removed "internal error" from token.cpp, since in this case varid would be NULL.

Redundant conditions: some refactorings
...
* removed the 'redundant null pointer' check. sometimes it's unsafe to delete NULL pointer. and this check doesn't point out errors anyway.
* moved the 'redundant condition' check for set::remove. Moved it to CheckStl.
