Only pull in locale.h as needed and move it to the common nls.h.
When editing a disk image, fdisk wants to ask the kernel to reread the
partition table which is useless and provokes an error, a wrong exit
code and some waiting. This annoys me as I can't check the return code
in my script and because I have to wait a few seconds each time.
This trivial patch makes it only do the ioctl on block devices.
It also simplifies code by dropping some workaround for kernel 1.2.x
mount: chain of symlinks to fstab causes use of pointer after free
Looking at the source in 'mount/realpath.c' we find that when dealing with
the second or later symlink in the chain, a memory block was free()d before
copying its contents to a newly allocated block.

mount: fix incorrect behavior when more than one fs type is specified
"mount" may fail when more than one file system type is specified, and the
requested access mode is read/write, but the device is read-only. The error
message is: "mount: wrong fs type, bad option, bad superblock on...".
It works only if the correct file system type is the last item in the comma
separated list. This is because when it tries to mount the file system again
in read-only mode, the "types" parameter passed to the "try_mount_one"
function contains only the last item instead of the entire list.
For example, you cannot mount a UDF CD/DVD with "-t udf,iso9660" if you
don't also add the read-only option. This means that some Linux distributions
with the default configuration may not be able to mount UDF disks
automatically (e.g. Ubuntu Dapper - Gutsy Tribe 3).

script: fix race conditions
script(1) uses three processes (doinput, dooutput and doshell). It's
possible that the shell process is finished before the input and
output processes are completely initialized. For example:
$ script -c "printf Bingo"
In particular case the output and input processes read/write data from
shell process in time when the shell process is already done -- so it
hangs on read().
The second problem is that the output process can finish although
there are unread data from finished shell process -- an output in
the typescript file and on terminal is incomplete!
script(1) has to pass:
$ for i in `seq 1 1000`; do script -q -c "printf 'Bingo\n'"; done | grep -c Bingo

agetty: 8 bit characters on the Linux console lead to input corruption
8 bit characters on the Linux console lead to input corruption (e.g.
German umlauts). This is easily reproducable by inserting a login name with
umlaut and typing backspace afterwards.
agetty supports tty parity, which leads to getty treating these characters
as a 7bit char with set parity.
This patch by Samuel Thibault adds a new option -8 which disables parity
detection for ttys not used for serial logins.
| Note: With this patch, 8bit characters are just silently dropped (that's
| the expected getty behavior), this is quite neat since you then don't
| even need to backspace your 8bit characters :)
