Subject: [PATCH] linux: Add a may_fail paramter to linux_parse_vt_settings
linux_parse_vt_settings() was split out of xf86OpenConsole so that it can
be called earlier during systemd-logind init, but it is possible to run
the xserver in such a way that xf86OpenConsole() is never used.
The FatalError calls in linux_parse_vt_settings() may stop the Xorg xserver
from working when e.g. no /dev/tty0 is present in such a setup.
This commit adds a may_fail parameter to linux_parse_vt_settings() which
can be used to make linux_parse_vt_settings() fail silenty with an error
return in this case, rather then calling FatalError().

Subject: [PATCH] linux: Add linux_parse_vt_settings and linux_get_keeptty
helpers
systemd-logind integration does not work when starting X on a new tty, as
that detaches X from the current session and after hat systemd-logind revokes
all rights on any already open fds and refuses to open new fds for X.
This means that currently e.g. "startx -- vt7" breaks, and breaks badly,
requiring ssh access to the system to kill X.
The fix for this is easy, we must not use systemd-logind integration when
not using KeepTty, or iow we may only use systemd-logind integration together
with KeepTty.
But the final KeepTty value is not known until the code to chose which vtno to
run on has been called, which currently happens after intializing
systemd-logind.
This commit is step 1 in fixing the "startx -- vt7" breakage, it factors out
the linux xf86OpenConsole bits which set xf86Info.vtno and keepTty so that
these can be called earlier. Calling this earlier is safe as this code has
no side effects other than setting xf86Info.vtno and keepTty.
Note this basically only moves a large chunk of xf86OpenConsole() into
linux_parse_vt_settings() without changing a single line of it, this is
hard to see in the diff because the identation level has changed.

Subject: [PATCH] systemd-logind: do not rely on directed signals
Right now, Xorg does not install DBus matches for "PauseDevice" /
"ResumeDevice". Therefore, it should usually not receive those DBus
signals from logind. It is just a coincidence that systemd-logind sends
those signals in a directed manner right now. Therefore, dbus-daemon
bypasses the broadcast matches.
However, this is not ABI and Xorg should not rely on this. systemd-logind
is free to send those signals as broadcasts, in which case Xorg will
freeze the VT. Fix this by always installing those matches.
