[analyzer] MacOSKeychainAPIChecker: Add reasoning about functions which MIGHT deallocate the memory region allocated with SecKeychain APIs. Specifically, when the buffer is passed to CFStringCreateWithBytesNoCopy along with a custom deallocator, which might potentially correctly release the memory.

[analyzer] MacOSKeychainAPIChecker: Users of KeyChain API often use free() to deallocate the password. Catch this error explicitly and generate the error message at the place where free() is called.

Report errors earlier: on checkDeadSymbols() and clear the state after the symbol we are tracking goes out of scope.
Also, perform lazy error checking. Instead of forcing the paths to be split depending one the return value of the allocator, make the return symbol depend on the allocated data symbol, which prolongs its life span to the time when the allocated data symbol becomes dead.

Add a skeleton for the Keychain Services API Checker. Register it as OSX experimental for now. Note, the checker still does not handle tracking of escaped values, taking into account the return value of the allocator functions, nor the actual bug reporting..
