We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

All udev state is kept in /$udev_root/.udev/ now. No option to
configure that anymore, it will always be there.

No device node or symlink can have other characters as plain
readable ascii or valid utf8. The /dev/disk/by-label/* symlinks
can no longer contain weird stuff read from untrusted sources.

This can be uses to export stuff to the event environment or
to carry a state from one rule to another, like enabling/disabling
later rules conditionally.

From: Bill Nottingham <notting@redhat.com>
Changed reading of firmware blob to mmap and let firmware_helper
follow the setting of the log level with UDEV_LOG.

This will allow us to have whole blocks of rules to skip
conditionally. The following section creates the node "yes":
GOTO="TEST"
NAME="no"
NAME="no2", LABEL="NO"
NAME="yes", LABEL="TEST"
NAME="no3"

This allows to source-in a file into the udev environment to have
the defined keys available for later processing by udev itself or
the forked helper programs.

All the rule files can be compiled into a single file,
which can be mapped into the udev process to avoid parsing
the rules with every event.

Former values are cleared if SYMLINK=<value> is used. To add a value
SYMLINK+=<value> is now needed.

Modern rules are expected to call notification and postprocessing with
the RUN key. For compatibility the current behavior can be emulated
with an external helper.

The use of KEY:=<value> will make the key unchangeable by later rules.

Here's a long overdue update to the udev rules docs, based on lots of user
feedback from the last few months.
Mostly updates to keep up with the new udev features, some clarifications and
wording improvements. I added a section on rules for palm pilots due to the
excessive amount of mail I get about them. I removed the nvidia stuff because
it's out of date. Added another section about debugging using logs and
udevtest. Removed the thanks list because I haven't been updating it and there
are too many people to name now, sorry..!

Now the tests should work again...

Yeah, I guess it's broken. In create_node() in udev_add.c there is
always added 1 to the minor number, thus the error. The attached patch
should fix this.

SUBSYSTEM=="block", RUN="/sbin/program"
will execute the program only for block device events.
ACTION="remove", SUBSYSTEM=="block", RUN"/sbin/program"
will execute the program, if a block device is removed.

Better remove characters that are useless in a device node name.
It may be a security risk to pass any character read from e.g. a
sysfs attribute to a shell script we execute later.
Prevent the modification of the libsysfs attribute value
cache.
Clear PROGRAM result if the execution encountered an error.
