Title: Implement "jumping to declaration" on irony-server.

Jump to the declaration of the symbol on a specific location.

Usage: irony-server find-declaration file-path line col

Output: ("path-to-file-with-declaration" line col)

Besides it can jump to the definition of some symbols, such as macros, it's also useful to find out which header file contains declaration of a symbol.
