Aaron Ballman 0dd49a5628 Use functions with prototypes when appropriate; NFC 
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 eighth batch of tests being updated (there are a
significant number of other tests left to be updated).

Balazs Benics edde4efc66 [analyzer] Introduce the assume-controlled-environment config option 
If the `assume-controlled-environment` is `true`, we should expect `getenv()`
to succeed, and the result should not be considered tainted.
By default, the option will be `false`.
