a83b64d15d Rework how linkage attributes are determined 
The meta items within a crate's link attribute are used in linkage:

 #[link(name = "std",
        vers = "1.0",
        custom = "whatever")];

Name and vers are treated specially, and everything else is hashed together
into the crate meta hash.

9561def209 Use 'resource' rather than 'res' as a keyword 
Resources are now defined like...

    resource fd(int n) { close(n); }

Calling fd with an int will then produce a non-copyable value
that, when dropped, will call close on the given int.

85b5b2a8e4 Tests for while loops that may invalidate constraints 
Wrote some small test cases that use while loops and moves, to
make sure the poststate for the loop body gets propagated into the
new prestate and deinitialization gets reflected.

Along with that, rewrite the code for intersecting states. I still
find it dodgy, but I guess I'll continue trying to add more tests.
Also, I'll probably feel better about it once I start formalizing
the algorithm.

7fb35ecf84 Serialize constraints in types (literal arguments still not supported) 
This involved, in part, changing the ast::def type so that a def_fn
has a "purity" field. This lets the typechecker determine whether
functions defined in other crates are pure.

It also required updating some error messages in tests. As a test
for cross-crate constrained functions, I added a safe_slice function
to std::str (slice(), with one of the asserts replaced with a
function precondition) and some test cases (various versions of
fn-constraint.rs) that call it. Also, I changed "fn" to "pred" for
some of the boolean functions in std::uint.

7fc89f573d Restructure the "checking" pass in typestate 
I noticed that typestate was being lazier than it should be,
because it was only checking typestate for statements and
top-level expression (that is, the expression in a stmt_expr, but
not any subexpressions). So I rewrote the checks in tstate/ck.rs
to use walk, which exposed a few bugs in typestate that I fixed.

Also added some more test cases for if-check.

d1857d30fc This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc).

147b088125 Test for use of break as an expression

1a96e79fe0 Make _|_ unify with anything 
The typechecker had a number of special cases for unifying types
with _|_ (as with checking if and alt). But, a value of type _|_
should be usable in any context, as such a value always diverges,
and will never be used by its immediate context. Changed unify
accordingly, removed special cases.

b620be9cd2 Typecheck @[] correctly 
Previously, if you wrote
let @vec[int] foo = @[];

that would be a type error. That didn't seem right, so I changed
pushdown to unify the inner type in an unop application with the
argument type of the operator type.

a98ea4f3ef rustc: Run block cleanups on else if blocks 
With the scheme used to translate 'else if' currently the if expression is
translated in a new (else) scope context. If that if expression wants to
result in a value that requires refcounting then it will need to drop the
refcount in the cleanups of the else block.
