ujail: rework fs jail part
Change functions to work with full paths (do less split and concat of path)
Store "soname" as key and the fullpath as path in "libraries"
Remove "extras" list and replace it with "mounts" avl_tree
("mounts" also store fullpath)
Add add_path_and_deps() function to handle file/lib openning and mmaping
Check if file is an elf (magic number) before passing it to elf_load_deps()
elf_load_deps() now only handle elf parsing part
next commit adds script (#!) handling

procd: Make askconsole work again when no tty is specified in inittab
Consider:
::askconsole:/bin/ash --login
askconsole( ) checks for the existance of the tty, but if none is
specified it will skip the remainder of the function. This means
fork_worker( ) is never called and no process is spawned. This
would leave routers without an initial console.

Honour tty field in /etc/inittab
The problem was caused by procd not opening /dev/tty* (whichever was

This is a rework of
e63051d9, which did not initialise the console
pointer and did not check the tty pointer in askconsole. askfirst
was not completely fixed as it expected the console parameter on
the commandline, which is no longer necessary because procd opens
the console prior to fork()-ing.

Show the shutdown sequence on the active virtual terminal
procd by default writes to /dev/console. When rebooting, this means that the
terminal on which the reboot sequence was started will not see what is going
on. This patch fixes that by reopening stdin, stdout and stderr to the console
device specified on the commandline, /dev/tty0 or /dev/console upon reboot.
Also, due to (probably) pivot-root, /proc/1/fd shows 1-3 pointing to
/console. This patch also fixes that.

Fix scroll lock blocking procd
On x86, pressing the scrolllock button may effectively prevent procd from rebooting
the system. This happens because procd tries to write to /dev/console, which in that
situation is blocked, effectively blocking procd from rebooting the system.
This patch puts procd's stderr access into non-blocking, which will prevent the
boot from being stuck.

Reboot busybox style via procd
It has been observed that, very rarely, the system does not reboot
when procd enters the shutdown state. Busybox seems to have an
obscure fix in its shutdown, where the parent (procd) process
is put in an infinite loop, and a special child is executed to
execute reboot(). This may very well be the cause.
