b4c88cdcec add uv::loop_delete() 
because of the last change, the loop ptr is no longer cleaned up
when the loop exits. This api call addresses that. Sadly, the loop
ptr is not "reusable" across multiple calls to uv::run().

9f49293232 rt: Initialize Windows CRITICAL_SECTION with non-zero spin count 
If a CRITICAL_SECTION is not initialized with a spin count, it will
default to 0, even on multi-processor systems. MSDN suggests using
4000. On single-processor systems, the spin count parameter is ignored
and the critical section's spin count defaults to 0.

For Windows >= Vista, extra debug info is allocated for
CRITICAL_SECTIONs but not released in a timely manner. Consider using
InitializeCriticalSectionEx(CRITICAL_SECTION_NO_DEBUG_INFO).

d01e7cd340 Represent boxed ifaces in a way similar to functions 
They are now a (dictptr, box) pair, where box is a regular boxed
representation of the inner type. This cuts down on some special
case code.

Also removes some code from trans::base that was moved to shape but
then somehow restored in trans::base through a bad merge.

35ba9715fa core: Add task::spawn_sched 
This function creates a new scheduler with a specified number of threads and
immediately executes a task on it. The scheduler is configured to terminate
when the task dies. This is the minimum API necessary to enable blocking C
calls.

Brian Anderson
028af5cb6c rt: Change the lifecycle of tasks and schedulers for various reasons 
This is in preparation for giving schedulers their own life cycle separate
from the kernel.

Tasks must be deleted before their scheduler thread, so we can't let the
scheduler exit before all its tasks have been cleaned up. In this scheme,
the scheduler will unregister tasks with the kernel when they are reaped,
then drop their ref on the task (there may still be others). When the task
ref count hits zero, the task will request to be unregistered from the
scheduler, which is responsible for deleting the task.

Instead of having the kernel tell the scheduler to exit, let the scheduler
decide when to exit. For now it will exit when all of its tasks are
unregistered.

f39e64d56a rt: Change the scheme used for terminating the kernel 
Instead of joining on the scheduler threads, instead keep a count of active
schedulers. When there are no more schedulers raise a signal for the main
thread to continue.

This will be required once schedulers can be added and removed from the
running kernel.

This simplifies the check for thread ownership by removing the _locked flag
and just comparing against the thread ID of the last thread to take the lock.
If the running thread took the lock _holding_thread will be equal to
pthread_self(); if _holding_thread is some other value then the running thread
does not have the lock.

Setting a pthread_t to 0 like this is not portable but should work on every
platform we are likely to care about for the near future.

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.

bd6b80c972 rt: Get rid of the rethrow in upcall_fail 
Throwing in upcall_fail ends up running lots of code in the red zone. To avoid
it we have the personality function figure out which stack it's on and switch
as needed.

c73eb8ff51 rt: Create different stack-switching paths for upcalls and shims 
Shims need to play with the stack limit, upcalls don't. Only one upcall,
upcall_fail is allowed to catch, and we need a find a way to get rid of that
catch as well because it results in _Unwind_Resume running off the end of the
Rust stack.

fe683dfb80 rt: Get rid of the valgrind guard bytes at the end of the stack 
Preventing us from writing beyond our allocations is _what valgrind does_,
so telling valgrind not to let us write to the end of the stack isn't
buying anything.

7d51961b6f rt: Fix saved address of unwinding %rsp in __morestack 
I haven't thought too deeply about this, but I think I was telling the
unwinder to use the stack pointer for the wrong frame when unwinding. Not sure
how that could have worked at all, but this results in the correct alignment
for cleanups.
