C++: Improve file accuracy when finding symbols
This patch introduces a priority-based mechanism when searching for certains
symbols in the snapshot. The priority corresponds to how similar the file path
from the "reference" symbol is to the file path from the "candidate" symbol.
This solves a variety of issues when matching "equivalent" symbols but that
are in another file/project, such as when following a function declaration,
a forward class declaration, or adding a definition through a quickfix.
There's now a symbol finder which will compute the "best" search order and cache
the most recent results. A consequence is that following symbols in some cases
is slower, but not apparently significatly.
Note: The "find" functions were moved from the Snapshot to the new SymbolFinder
class.
