16652c9c17 auto merge of #5909 : brson/rust/rt4, r=graydon 
This is just a bunch of minor changes and simplifications to the structure of core::rt. It makes ownership of the ~Scheduler more strict (though it is still mutably aliased sometimes), turns the scheduler cleanup_jobs vector into just a single job, shunts the thread-local scheduler code off to its own file.

fdb4ef321e auto merge of #5726 : brson/rust/struct-return, r=brson 
r? @nikomatsakis

This doesn't completely fix the x86 ABI for structs, but it does fix some cases. On linux, structs appear to be returned correctly now. On windows, structs are only returned by pointer when they are greater than 8 bytes. That scenario works now.

In the case where the struct is less than 8 bytes our generated code looks peculiar. When returning a pair of u16, C packs both variables into %eax to return them. Our generated code though expects to find one of the pair in %ax and the other in %dx. Similar for u8. I haven't looked into it yet.

There appears to also be struct passing problems on linux, where my `extern-pass-TwoU8s` and `extern-pass-TwoU16s` tests are failing.

a5ddc00982 rustc: Use an out pointer to return structs in x86 C ABI. #5347 
This Adds a bunch of tests for passing and returning structs
of various sizes to C. It fixes the struct return rules on unix,
and on windows for structs of size > 8 bytes. Struct passing
on unix for structs under a certain size appears to still be broken.

68583a25a0 core::rt: Restructure context switches to take ownership of the Scheduler 
In order to do a context switch you have to give up ownership of the scheduler,
effectively passing it to the next execution context. This could help avoid
some situations here tasks retain unsafe pointers to schedulers between context
switches, across which they may have changed threads.

There are still a number of uses of unsafe scheduler pointers.

6965fe4bce Add AbiSet and integrate it into the AST. 
I believe this patch incorporates all expected syntax changes from extern
function reform (#3678). You can now write things like:

    extern "<abi>" fn foo(s: S) -> T { ... }
    extern "<abi>" mod { ... }
    extern "<abi>" fn(S) -> T

The ABI for foreign functions is taken from this syntax (rather than from an
annotation).  We support the full ABI specification I described on the mailing
list.  The correct ABI is chosen based on the target architecture.

Calls by pointer to C functions are not yet supported, and the Rust type of
crust fns is still *u8.

efc7f82bc4 Revamp foreign code not to consider the Rust modes. This requires 
adjusting a few foreign functions that were declared with by-ref
mode.  This also allows us to remove by-val mode in the near future.

With copy mode, though, we have to be careful because Rust will implicitly pass
somethings by pointer but this may not be the C ABI rules.  For example, rust
will pass a struct Foo as a Foo*.  So I added some code into the adapters to
fix this (though the C ABI rules may put the pointer back, oh well).

This patch also includes a lint mode for the use of by-ref mode
in foreign functions as the semantics of this have changed.
