udevd: always try to find an idle worker instead of forking a new one
We special-handle events with a TIMEOUT= set, so they don't get queued
or wait for parent events to finish, to make sure we can handle them
as fast as possible.
With this change we first try to find an idle worker process before
forking a new one.

Fix volume keys not releasing for Pegatron platform
Pegatron has a new platform coming out being sold by many small
manufacturers. This platform has volume keys that are not sending a key
release. This patch ensures those keys send release.

readlink does not write a nul character to the end of the
string it returns. Therefore ask for one fewer character
than the buffer size so there's always room for an extra \0.

keymap: Unite laptop models needing common volume-key release quirk
Many laptop models need the same volume-key release quirk. Currently, two
models have identical force-release-maps/ keymap files (dell-studio-1557 and
fujitsu-amilo-si1848) and two more need to be added (Mitac and Coolbox QBook).
This replaces the identical force-release-maps files with one
'common-volume-keys' file to make adding new models easier.
There is no obvious DMI commonality between the models needing the quirk (i.e.
they do not all share the same BIOS), so it will remain necessary to scan for
each model separately in 95-keyboard-force-release.rules.

Do not pretend to have a media, when we receive a profile like 0x02,
which just means "Removable disk".

cdrom_id: Swap media state and TOC info probing
Blank CDs do not have a TOC, thus will fail cd_media_toc() (at least with the
"Do not ignore errors from scsi_cmd_run()" fix). Thus probe the media state
first, so that we can properly detect blank media.

cdrom_id: Do not ignore errors from scsi_cmd_run()
scsi_cmd_run() can return positive error messages if we have CHECK_CONDITION
set and get the error code from the SCSI command result. So check the result
for non-zero, not for being negative.
This should fix another cause for "phantom" media in empty CD-ROM drives.

cdrom_id: Fix uninitialized buffers
Commit 5c6954f is actually a no-op, since static variables are already zero'ed
by default anyway (but we keep it for clarity). The real difference was that a
build with -O0 wor while a build with -O2 didn't.
Turns out that some ioctls do not actually touch the result buffer in some
cases, so we need to zero the result buffers to avoid interpreting random da as
CD properties.

cdrom_id: Fix uninitialized variables
In cases where cdrom_id does not go through the entire code path and one of the
probing functions returns -1 or exits early, the remaining variables were never
initialized. This caused effects like "phantom" audio CDs on empty drives, or
bogus data like ID_CDROM_MEDIA_TRACK_COUNT=22528.
Initialize the variables right away to avoid that.

Fix Keymapping for upcoming Dell Laptops
This patch fixes it so that new upcoming Dell machines will work
correctly if users presses the touchpad toggle key.
Currently 0xD8 is being mapped to sleep. Though this is only done by the
Latitude XT* laptops. Many upcoming Laptops from Dell are mapping this
key to "toogle touchpad off" .. giving the OS notification that it has
just turned off the touchpad.
Though their is an issue in that if this key is mapped the hardware
first toogles .. then the software tries to do the samething after, if
they fall out of sync ... no more touchpad. So leave out mapping these
keys for now.
