Implementation mising features in lock_and_signal for Win32. Also lowered the minimum stack size to get the pfib benchmark to run without exhausting its address space on Windows.

Conservatively serialize nearly all upcalls. Successfuly ran make check with RUST_THREADS=8, so we're probably fairly safe now. In the future we can relax the synchronization to get better performance.

Fixed a few concurrency bugs. Still not perfect, but overall it seems much more reliable.

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.

Overhaul logging system in runtime
...
See https://github.com/graydon/rust/wiki/Logging-vision
The runtime logging categories are now treated in the same way as
modules in compiled code. Each domain now has a log_lvl that can be
used to restrict the logging from that domain (will be used to allow
logging to be restricted to a single domain).
Features dropped (can be brought back to life if there is interest):
- Logger indentation
- Multiple categories per log statement
- I possibly broke some of the color code -- it confuses me

No functions should be called for log statements that turn out to be
inactive.

Lots of design changes around proxies and message passing. Made it so that domains can only talk to other domains via handles, and with the help of the rust_kernel.

Synthesize a flush_chan upcall right before a channel's ref_count drops to zero. This should only happen in the Rust code and not in the drop glue, or on the unwind path. This change allows the task owning the channel to block on a flush and delete its own channel. This change also cleans up some code around rust_port and rust_chan.
