1c7a62c93b Use a memset upcall to zero things without static alignment 
This fixes issues #843 and #1546. The cost of an upcall is
unfortunate, though. I assume there must be a way to simply manually
compute the pointer or size, using something akin to the formula in
`align_to` in `rust_util.h`. I could not get this to work,
unfortunately.

9a738fd61d rt: Various tweaks to make __morestack unwinding work on linux 
When unwinding through __morestack the stack limit in the TLS is invalidated
and must be reset. Instead of actually landing at __morestack we're
just going to make all our Rust landing pads call upcall_reset_stack_limit,
which will find the stack segment that corresponds to the current stack
pointer and put the limit in the TLS.

Also massively expand the stack segment red zone to make more room for the
dynamic linker. Will fix in the future.

e075412a92 build: Stop linking morestack.S to rt 
__morestack has to be linked statically. The odd calling convention on x86_64
results in the arguments to __morestack (r10 & r11) being clobbered by the
dynamic linker. gcc links all the __morestack functions statically.

02d7a1e781 move sys fns into c-stack-cdecl and get_type_desc() into rusti 
there is one test failure, stdtest/sys.rs, which inexplicably
(thus far) fails to compile because it invokes
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.

25ae3d655c Rewrite spawn yet again 
The motivation here is that the bottom of each stack needs to contain a C++

not spawned tasks.

c9c5ee252a Implement non-internal ivecs 
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.

Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.

e58c48bdda Optimize += [x] into a simple push operation 
This is a preparation for making vectors always-on-the-heap again,

add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

8878b128ba More work on word-count. 
Updated the MapReduce protocol so that it's correct more often. It's
still not perfect, but the bugs repro less often now.

Also found a race condition in channel sending. The problem is that
send and receive both need to refer to the _unread field in
circular_buffer. For now I just grabbed the port lock to send. We can
probably get around this by using atomics instead.

Eric Holk
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.

errors. I am so sorry.
