Allow namespace override.
This change allows a
#[namespace (namespace = A::B)]
attribute for each item in a cxx::bridge.
We now have a fair number of different types of name floating
around:
* C++ identifiers
* C++ fully-qualified names
* Rust identifiers
* Rust fully-qualified names (future, when we support sub-modules)
* Items with both a Rust and C++ name (a 'Pair')
* Types with only a known Rust name, which can be resolved to a
C++ name.
This change attempts to put some sensible names for all these
things in syntax/mod.rs, and so that would be a good place to start
review.
At the moment, the Namespace (included in each CppName)
is ruthlessly cloned all over the place. As a given namespace is
likely to be applicable to many types and functions, it may
save significant memory in future to use Rc<> here. But let's not
optimise too early.
