This fixes invocations of certain commands when python3 is installed in
a nonstandard path (/usr/local/bin, for example).

Add a higher level console API that opens a tty/console and runs the
mainloop as well. Rename existing API to console_getfd(). Use these in
the python binding.
Allow attaching a console peer after container bootup, including if the
container was launched with -d. This is made possible by allocation of a
"proxy" pty as the peer when the console is attached to.
Improve handling of SIGWINCH, the pty size will be correctly set at the
beginning of a session and future changes when using the lxc_console() API
will be propagated to it as well.
Refactor some common code between lxc_console.c and console.c. The variable
wait4q (renamed to saw_escape) was static, making the mainloop callback not
safe across threads. This wasn't a problem when the callback was in the
non-threaded lxc-console, but now that it is internal to console.c, we have
to take care of it. This is now contained in a per-tty state structure.
Don't attempt to open /dev/null as the console peer since /dev/null cannot
be added to the mainloop (epoll_ctl() fails with EPERM). This isn't needed
to get the console setup (and the log to work) since the case of not having
a peer at console init time has to be handled to allow for attaching to it
later.
Move signalfd libc wrapper/replacement to utils.h.
