Aaron Ballman 1ea584377e 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).

Artem Dergachev 8b2a39e937 [analyzer] Trust global initializers when analyzing main().
If the global variable has an initializer, we'll ignore it because we're usually
not analyzing the program from the beginning, which means that the global
variable may have changed before we start our analysis.

However when we're analyzing main() as the top-level function, we can rely
on global initializers to still be valid. At least in C; in C++ we have global
constructors that can still break this logic.

This patch allows the Static Analyzer to load constant initializers from
global variables if the top-level function of the current analysis is main().
