252b8ffe42 Add support for new-style local decls 
let x = 5;
    let y: int = 10;
    // as soon as a typestate bug is fixed:
    let x: str = foo, y <- 20u;

'auto' and 'type-first let' will soon be dropped.

The old syntax is also still supported.

f0be65cb50 Fix span information returned by parser::parse_seq

properly reports the end of the closing token.

b9b674abe7 Start adding support for multiple variable declarations per stmt 
This adds parser support and most of the machinery for

    auto x = 10, y = 20;

However, the above still goes wrong somewhere in typestate, causing
the state checker to believe only the last variable in the list is
initialized after the statement.

Tim, if you have a moment, could you go over the changes to the tstate
code in this patch and see where I'm going wrong?

Multi-var-decls without the typestate extension

Add a loop

93ffed4c16 Fix unboxing in alias pass 
The alias checker would only deref once for autoderef, and only deref
boxes. It should now do the right thing. Closes #725.

3b2d23b2cd Move a bunch of trans into trans_common, including the context structures. 
Probably more should be moved or split off into other files. My algorithm
was something along the lines of: move the contexts and their transitive
dependencies along with some functions to work with them. I stopped when
I was going to have to start pulling glue generation, which really
should go into a trans_glue file.

f8bb5a3b58 Make ty::ctxt be boxed. 
Arguably we should leave ty_ctxt as a bare rec and just always work with
boxes of it. This winds up being simpler and prettier, though.

a9a1392b2c Instantiate function preconditions inside the function body 
so that if we have a function like:
f(...) : p(x) {
  ...
}

p(x) is true inside the body of f.

d79afd7916 Improving move semantics for channel operations.

3ae4dcd41e Lots of work on memory tracking and channels. 
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.
