std/rustc/rustpkg/syntax: Support the `extern mod = ...` form 

This commit allows you to write:

 extern mod x = "a/b/c";

which means rustc will search in the RUST_PATH for a package with
ID a/b/c, and bind it to the name `x` if it's found.

Incidentally, move get_relative_to from back::rpath into std::path

The external crate is resolved to a specific `soname` at compile time,
and a runtime linkage requirement to that `soname` is passed to the linker for
loading at runtime. The `soname` is resolved at compile time by scanning the
compiler's library path and matching the `link_attrs` provided in the
`use_decl` against any `#link` attributes that were declared on the external
crate when it was compiled. If no `link_attrs` are provided, a default `name`
attribute is assumed, equal to the `ident` given in the `use_decl`.
loading at runtime.
The `soname` is resolved at compile time by scanning the compiler's library path
and matching the `link_attrs` provided in the `use_decl` against any `#link` attributes that
were declared on the external crate when it was compiled.
If no `link_attrs` are provided,
a default `name` attribute is assumed,
equal to the `ident` given in the `use_decl`.
Three examples of `extern mod` declarations:
Optionally, an identifier in an `extern mod` declaration may be followed by an equals sign,
then a string literal denoting a relative path on the filesystem.
This path should exist in one of the directories in the Rust path,
which by default contains the `.rust` subdirectory of the current directory and each of its parents,
as well as any directories in the colon-separated (or semicolon-separated on Windows)
list of paths that is the `RUST_PATH` environment variable.
The meaning of `extern mod a = "b/c/d";`, supposing that `/a` is in the RUST_PATH,
is that the name `a` should be taken as a reference to the crate whose absolute location is
`/a/b/c/d`.
Four examples of `extern mod` declarations:
