3cfcdb4bb2 rt: Replace two uses of yield with ctx->swap 
These uses aren't really doing a full yield. They are just giving up control
to the scheduler and will never return.

3a6320f71b intrinsics: Eliminate recv intrinsic 
This intrinsic existed just to get ahold of the return pointer. I replaced it
with a call_with_retptr intrinsic that grabs the return pointer and passes it
to another Rust function, thereby eliminating the need to call C functions on
the Rust stack.

sys::rustrt::last_os_error() instead of invoking
sys::last_os_error().  If stdtest/sys.rs is updated to invoke
the wrapper, it passes.  Still tracing the source of this error.

5f066e06b9 Update to libuv commit 3ca382. 
This patch changes libuv's gyp build system to
make it's own makefiles. To generate them for rust,
run these commands. They requires python 2.x to
work:

$ mkdir -p src/rt/libuv/build
$ svn co http://gyp.googlecode.com/svn src/rt/libuv/build/gyp
$ ./etc/src/gyp_uv

c047cfb710 Unwind the stack on task failure 
When a task fails, we will throw an exception, then catch it at the bottom of
the stack.

On Windows we don't do this yet because the exception doesn't propagate
correctly.

No cleanups yet.

25ae3d655c Rewrite spawn yet again 
The motivation here is that the bottom of each stack needs to contain a C++
try/catch block so that we can unwind. This is already the case for main, but
not spawned tasks.
