[clang][analyzer] Merge apiModeling.StdCLibraryFunctions and StdCLibraryFunctionArgs checkers into one.
Main reason for this change is that these checkers were implemented in the same class
but had different dependency ordering. (NonNullParamChecker should run before StdCLibraryFunctionArgs
to get more special warning about null arguments, but the apiModeling.StdCLibraryFunctions was a modeling
checker that should run before other non-modeling checkers. The modeling checker changes state in a way
that makes it impossible to detect a null argument by NonNullParamChecker.)
To make it more simple, the modeling part is removed as separate checker and can be only used if
checker StdCLibraryFunctions is turned on, that produces the warnings too. Modeling the functions
without bug detection (for invalid argument) is not possible. The modeling of standard functions
does not happen by default from this change on.

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).

[analyzer][StdLibraryFunctionsChecker] Track dependent arguments
When we report an argument constraint violation, we should track those
other arguments that participate in the evaluation of the violation. By
default, we depend only on the argument that is constrained, however,
there are some special cases like the buffer size constraint that might
be encoded in another argument(s).
