Kevin Krakauer 0a8a75f3da Job control: controlling TTYs and foreground process groups.
Adresses a deadlock with the rolled back change:
b6a5b950d2
Creating a session from an orphaned process group was causing a lock to be
acquired twice by a single goroutine. This behavior is addressed, and a test
(OrphanRegression) has been added to pty.cc.

Implemented the following ioctls:
- TIOCSCTTY - set controlling TTY
- TIOCNOTTY - remove controlling tty, maybe signal some other processes
- TIOCGPGRP - get foreground process group. Also enables tcgetpgrp().
- TIOCSPGRP - set foreground process group. Also enabled tcsetpgrp().

Next steps are to actually turn terminal-generated control characters (e.g. C^c)
into signals to the proper process groups, and to send SIGTTOU and SIGTTIN when
appropriate.

Andrei Vagin 9e1c253fe8 gvisor: run bazel in a docker container
bazel has a lot of dependencies and users don't want to install them
just to build gvisor.

These changes allows to run bazel in a docker container.
A bazel cache is on the local file system (~/.cache/bazel), so
incremental builds should be fast event after recreating a bazel
container.

Here is an example how to build runsc:
make BAZEL_OPTIONS="build runsc:runsc" bazel

Kevin Krakauer 82529becae Fix index out of bounds in tty implementation.
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.
