This will allow capturing of common things like logging messages, stdout prints
(using stdio println), and failure messages (printed to stderr). Any new prints
added to libstd should be funneled through these task handles to allow capture
as well.
Additionally, this commit redirects logging back through a `Logger` trait so the
log level can be usefully consumed by an arbitrary logger.
This commit also introduces methods to set the task-local stdout handles:
* std::io::stdio::set_stdout
* std::io::stdio::set_stderr
* std::io::logging::set_logger
These methods all return the previous logger just in case it needs to be used
for inspection.
I plan on using this infrastructure for extra::test soon, but we don't quite
have the primitives that I'd like to use for it, so it doesn't migrate
extra::test at this time.

libnative erroneously would attempt to fill the entire buffer in a call to
`read` before returning, when rather it should return immediately because
there's not guaranteed to be any data that will ever be received again.

Rearrange some code in rustpkg:
* Move command line argument parsing to parse_args.rs
* Introduce an enum to descibe commands such as Build, Install, and Clean.
* Move sysroot from Context to BuildContext, to make parse_args more modular.
This is my first pull request, so please tell me if there is anything I need to do.
The primary user of `@T`/`P<T>` references from `Visitor` was `ast_map`, which in turn had two users (phase 3 in rustc and a step in loading items from metadata).
Both of them have been rewritten to use `ast_map` as a folder (this might speed up the compilation time of stage2 rustc by 100-200ms just because a fold + a visit are merged together).
This requires a single `*mut` pointer to implement; I've justified its existence & correctness in the code.
Also, converts the mutable and immutable iterators to share code with some macro ~~madness~~ manipulation.
There was a scheduling race where a child may not increment the global task
count before the parent exits, and the parent would then think that there are no
more tasks left.

I've been wanting to explain default methods in the tutorial for ages. While I was at it I tried to clarify some other parts of the traits section. I'm sure this could be improved further; suggestions welcome.
This reverts commit f1b5f59287.
Using a private function of a library is a bad idea: several people (on
Linux) were meeting with linking errors because of it (different/older
versions of glibc).

If the main closure failed, then the `exit_code` variable would still be `None`,
and the `unwrap()` was failing (triggering a process abort). This changes the
`unwrap()` to an `unwrap_or()` in order to prevent process abort and detect when
the native task failed.
