b099b1e3f7 Make std::istr::push_byte efficient
It used to allocate two (!) heap values per pushed byte. It now goes through
a runtime function that simply grows the istr and writes the byte.

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,
which would cause way too much malloc traffic for this idiom. I will
add an efficient std::vec::push in the future, and migrate += [x] to
that instead.

Reduces compiler code size by 3%

e697a52359 Adding a function to stdlib to set the min stack size, for programs
that absolutely will not succeed with a large default stack. This
should be removed once we have stack grown working.

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.

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.

a467e8e4e6 Add a huge hack to allow the test runner to continue if a single task leaks
This is just until unwinding works. Adds a flag to the runtime to turn
the memory leak checks on task destruction into warnings instead of fatal
errors. I am so sorry.

f6117173c9 Allocate rust_ivec buffers out of the kernel pool
The duplication of upcalls is due to the fact that the runtime is

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).
This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.
