Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

We were setting queue.readable without holding the lock.

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

The previous implementation revolved around runes instead of bytes, which caused
weird behavior when converting between the two. For example, peekRune would read
the byte 0xff from a buffer, convert it to a rune, then return it. As rune is an
alias of int32, 0xff was 0-padded to int32(255), which is the hex code point for
?. However, peekRune also returned the length of the byte (1). When calling
utf8.EncodeRune, we only allocated 1 byte, but tried the write the 2-byte
character ?.
tl;dr: I apparently didn't understand runes when I wrote this.

Also, changing queue.writeBuf from a buffer.Bytes to a [][]byte should reduce
copying and reallocating of slices.

Implements the TIOCGWINSZ and TIOCSWINSZ ioctls, which allow processes to resize
the terminal. This allows, for example, sshd to properly set the window size for
ssh sessions.

Now, there's a waiter for each end (master and slave) of the TTY, and each
waiter.Entry is only enqueued in one of the waiters.

Minor refactor. line_discipline.go was home to 2 large structs (lineDiscipline
and queue), and queue is now large enough IMO to get its own file.
Also moves queue locks into the queue struct, making locking simpler.

Adds support for echo to terminals. Echoing is just copying input back out to
the user, e.g. when I type "foo" into a terminal, I expect "foo" to be echoed
back to my terminal.
Also makes the transform function part of the queue, eliminating the need to
pass them around together and the possibility of using the wrong transform for a
queue.
