Updates #2972

ioctl calls with TIOCSCTTY fail if the calling process already has a
controlling terminal, which occurs on a 5.4 kernel like our Ubuntu 18 CI.
Thus, run tests calling ioctl TTOCSCTTY in clean subprocess.
Also, while we're here, switch out non-inclusive master/slave for main/replica.

It was possible to panic the sentry by opening a cache revalidating folder with
O_TRUNC|O_CREAT.
Avoids breaking php tests.

Adresses a deadlock with the rolled back change:
https://github.com/google/gvisor/commit/b6a5b950d28e0b474fdad160b88bc15314cf9259
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.

This was accidentally introduced in 31f05d5d4f62c4cd4fe3b95b333d0130aae4b2c1.
Fixes #788.

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

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.
