1262df652f Reduce the amount of locking in the kernel's memory region 
The only thing here that really needs locking on malloc and free is
access to the allocation list, which is only used for TRACK_ALLOCATIONS.

Improves bench/task-perf-vector-party by 70%.

44bef5f2cb Introduced task handles. 
This is the new way to refer to tasks in rust-land. Currently all they
do is serve as a key to look up the old rust_task structure. Ideally
they won't be ref counted, but baby steps.

0fcd72c932 When using the allow leaks hack don't even print a warning about the leak 
This is only used for the test runner and in that case it just makes the test
output confusing

4ef1ec580a Do all runtime calls to getenv at initialization 
getenv is not threadsafe and (maybe as a result) it's randomly crashing with
CFLAGS=-g and RUST_THREADS=32. Calls from rust code are still on their
own.

d79afd7916 Improving move semantics for channel operations. 
This lets us un-XFAIL task-comm-10.rs.

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.

f6e37f659c Made TRACK_ALLOCATIONS add only constant time overhead. This makes it 
feasible to turn it on and run rustc.

8acadb17c2 Work on debugging race conditions. 
Ports and channels have been moved to the kernel pool, since they've
been known to outlive their associated task. This probably isn't the
right thing to do, the life cycle needs fixed instead.

Some refactorying in memory_region.cpp. Added a helper function to
increment and decrement the allocation counter. This makes it easier
to switch between atomic and non-atomic increments. Using atomic
increments for now, although this still does not fix the problem.
