This is just an implementation detail of using libuv, so move the libuv-specific
logic into librustuv.

This function had type &[u8] -> ~str, i.e. it allocates a string
internally, even though the non-allocating version that take &[u8] ->
&str and ~[u8] -> ~str are all that is necessary in most circumstances.

It's a more fitting name for the most common use case of this function.

BufferedWriter::inner flushes before returning the underlying writer.
BufferedWriter::write no longer flushes the underlying writer.
LineBufferedWriter::write flushes up to the *last* newline in the input
string, not the first.

This allows one to reduce the number of reallocs of the internal buffer
if one has an approximate idea of the size of the final output.

This also moves `#[auto_{en,de}code]` checker from syntax to lint.

This implements a fair amount of the unimpl() functionality in io::native
relating to filesystem operations. I've also modified all io::fs tests to run in
both a native and uv environment (so everything is actually tested).
There are a few bits of remaining functionality which I was unable to get
working:
* truncate on windows
* change_file_times on windows
* lstat on windows
I think that change_file_times may just need a better interface, but the other
two have large implementations in libuv which I didn't want to tackle trying to
copy. I found a `chsize` function to work for truncate on windows, but it
doesn't quite seem to be working out.

There are issues with reading stdin when it is actually attached to a pipe, but
I have run into no problems in writing to stdout/stderr when they are attached
to pipes.

This makes `Cell`s no longer necessary in most cases.

These commits create a `Buffer` trait in the `io` module which represents an I/O reader which is internally buffered. This abstraction is used to reasonably implement `read_line` and `read_until` along with at least an ok implementation of `read_char` (although I certainly haven't benchmarked `read_char`).

This commit re-organizes the io::native module slightly in order to have a
working implementation of rtio::IoFactory which uses native implementations. The
goal is to seamlessly multiplex among libuv/native implementations wherever
necessary.
Right now most of the native I/O is unimplemented, but we have existing bindings
for file descriptors and processes which have been hooked up. What this means is
that you can now invoke println!() from libstd with no local task, no local
scheduler, and even without libuv.
There's still plenty of work to do on the native I/O factory, but this is the
first steps into making it an official portion of the standard library. I don't
expect anyone to reach into io::native directly, but rather only std::io
primitives will be used. Each std::io interface seamlessly falls back onto the
native I/O implementation if the local scheduler doesn't have a libuv one
(hurray trait ojects!)

I implemented BufWriter. I realize the use of conditions are on their way out for IO, but it does raise a condition if a write will not fit in the buffer for now.
I also replaced the seek code for MemWriter. It was adding the offset as a uint, which is unsound for negative offsets. It only happened to work because unsigned addition performs the same operation with two's complement, and sizeof(uint) <= sizeof(i64) so there was no (lack of) sign extension. I replaced this with computing an offset as an i64 and clamping to zero. I don't expect anyone will have use BufWriter with a byte buffer greater than 2^63 bytes any time soon.

This trait is meant to abstract whether a reader is actually implemented with an
underlying buffer. For all readers which are implemented as such, we can
efficiently implement things like read_char, read_line, read_until, etc. There
are two required methods for managing the internal buffer, and otherwise
read_line and friends can all become default methods.
Closes #10334

Filled in the implementations of Writer and Seek for BufWriter. It
raises the io_error condition if a write cannot fit in the buffer.
The Seek implementation for MemWriter, which was incorrectly using
unsigned arithmatic to add signed offsets, has also been replaced.
