This patch brings the tty code more inline with what the logind code
Was doing. It also fixes the return value from the vt_signal handler,
and opens the tty in non-blocking mode now.

Summary:
printf %m stringifies and prints errno. I've tried to remove its use
anywhere that the immediately preceding function might not set errno
or is a complicated function for which knowing errno doesn't really
give any useful information.
I've left a few of the drmMode calls because they're just wrappers
around ioctl, which legitimately sets errno.

Summary: If we go to setup a tty and it is already in graphics mode,
then there is no need to exit with a failed setup here. Instead, we
can actually continue to setup the tty.

Summary: if ecore-drm failed to be run after changing tty mode, need to restore VT to text mode.
Test Plan:
- run enlightenment(drm backend) without systemd.
after changing tty graphics mode, if it's failed to be run by any reason,
you'll see black screen and coulnd't control session.

Summary: Because this is an exposed API function, we should be
checking that the name parameter is valid, and also verify it's
formatting before we use it. This patch fixes that by comparing the
passed in name and assembling a valid tty name to open

This commit fixes VT switching in the ecore_drm library code to work
again. Previously we were not dup'ing the stdin fd which lead to
inappropriate ioctls for that fd. Fix that by adding the missing dup
call. This also adds more error messages during ioctl function calls,
and cleans up the switching handler code (for keyboard events).

Summary:
Because vt mode of tty is set to VT_PROCESS,
ecore-drm is responsible for managing switch-to or switch-from other vt.
For that, ecore-drm has to handshake with kernel(tty driver).
On switch-from side(A):
1. Listen key event to satisfy vt switch key binding.
2. ioctl(fd, VT_ACTIVE, switch-to-vt) for activating switch-to vt.
3. Receive SIGUSR1(relsig) from kernel.
4. Prepare releasing vt, and ioctl(fd, VT_RELDISP, 1).
On switch-to side(B):
0. Kernel receive VT_RELDISP with value 1(ok) from switch-from vt.
1. Receive SIGUSR2(acqsig) from kernel.
2. ioctl(fd, VT_RELDISP, VT_ACKACQ), and start to setup vt.
This revision added A-1 step on above.
Test Plan:
On booted PC with systemd.
1. launch enlightenment_start with drm and wayland
ex) ECORE_DRM_TTY=/dev/tty1 \
E_WL_FORCE=drm \
ELM_ENGINE=wayland_shm enlightenment_start
2. try to switch vt by pressing "Ctrl + Alt + (F1 ~ F8)"

SIGUSR1 is used here to catch VT switching and either acquire or
release the VT. The problem is that XWayland Also sends SIGUSR1 when
it has finished initializing. In order to not get confused about where
the SIGUSR1 came from we can check the pid inside the siginfo
structure and see if it matches.
