Fix building of documentation when doing out-of-source builds.
Since gtk-mkhtml is executed in a sub-directory of the build directory, and
make does not know of that, the $(buildir) variable will still be "." and
the $(srcdir) will not properly be found. For this reason, use the absolute
variants for the two functions, which won't be changing.
Use the keymap check during “make distcheck” rather than “check”.
Since the check-keymaps.sh script checks for validity the source directory
and the Makefile.am file, instead of running it during user-oriented “make
check”, run it during developed-oriented “make distcheck”.
An invalid keymap will abort the execution which will prevent shipping
an incomplete Makefile.am.
To properly support out-of-source builds, pass as single parameter to the
test the path to the source directory.
Replace the custom test-run target with the standard make check.
A little fix is needed for the udev-test.pl script (to be called with the
proper path), but this allows for the test binaries to be only built when
running the tests themselves.
Merge libudev, udev, and the unconditional extras in a single Makefile.am.
Instead of using multiple recursive Makefile.am files, use a single
Makefile.am that sets and builds all the basic suite of libraries and
binaries for udev. This reduces the number of files in the source tree, and
also reduces drastically the build time when using parallel-make.
With this setup, all the compile steps will be executed in parallel, and
just the linking stage will be (partially) serialised on the libraries
creation.
- create an additional link with a shorter name
- create a link which matches more loosely
(omit certain path segments e.g. serial numbers)
- change permissions on certain USB device nodes
Allow them to realize this without reading the friendly *.c files.

man: fix unused, inaccurate metadata
Dates aren't shown in the manpages. So they are not really useful,
and no-one is going to remember to update them.
"<refmiscinfo class="version"></refmiscinfo>" sounds even less useful.
I leave the unused "title" and "productname" tags. They could
theoretically be useful, and aren't hard to maintain. We just need to
fix the "title" for udevadm.

re-enable failed event tracking
It did not work for the last couple of releases.
If RUN{record_failed}+="..." is given, a non-zero execution will mark
the event as failed. Recorded failed events can be re-triggered with:
udevadm trigger --type=failed
The failed tracking _might_ be useful for things which might not be
ready to be executed at early bootup, but a bit later when the needed
dependencies are available. In many cases though, it indicates that
something is used in a way it should not.
The errno value from getgrnam_r here is ERANGE which is documented as
"Insufficient buffer space supplied".
When I call get getgrnam_r with a large enough buffer everything
works. Indicating that the problem is that sysconf is returning
a value too small.
A quick google search tells me that sysconf(_S_GETGR_R_SIZE_MAX)
is documented as:
> sysconf(_S_GETGR_R_SIZE_MAX) returns either -1 or a good
> suggested starting value for buflen. It does not return the
> worst case possible for buflen.
In my case I have a group with about 50 users in /etc/group
and that is what triggered the problem in udev and caused
all of the udevs group lookups to fail.
The following patch which dynamically allocates the group member buffer
should fix this problem.

enumeration: move ALSA control devices to the end of the enumerated devices of each card
Generally ALSA control devices should be the last ones to be processed
for ACL changes and similar operations because they can then be used as
indicators that ACL management finished for all device nodes of a
specific card.
This patch simple moves each controlC device behind all the pcmC devices
(and similar).

hid2hci: rewrite (and break) rules and device handling
We must never access random devices in /dev which do not belong to
the event we are handling. Hard-coding /dev/hidrawX, and looping over all
devices is absolutely not acceptable --> hook into hidraw events.
We can not relay on (rather random) properties merged into the parent
device by earlier rules --> use libudev to find the sibling device
with a matching interface.
Libusb does not fit into udev's use case. We never want want to scan
and open() all usb devices in the system, just to find the device
we are already handling the event for --> put all the stupid scanning
into a single function and prepare for a fixed libusb or drop it later.

extras/keymap: Fix crash for unknown keys
The keymap table has some holes in it, which caused the interactive mode to

What's odd is that this is a huawei modem, not an option modem, so one would
expect it to work better with usb_modeswitch and it's -H (huawei) mode - but
that's not the case, I've tested that as well.

scsi_id: correct error handling in prepend_vendor_model
The callers of prepend_vendor_model both expect < 0 to be returned on
error and the index to be returned otherwise. However
prepend_vendor_model actually returns 1 on error. Fix this by correctly
returning -1.
Older kernels (before e5b3cd42: "SCSI: sanitize INQUIRY strings")
truncated the model field in sysfs (or propagated bad results from the
target) to less than the expected/required 16 characters which meant
that the SCSI id was mangled into:
# /sbin/scsi_id -g -s /block/sdg
S146cee20VIRTUAL-DISK
when it should have been:
# /sbin/scsi_id -g -s /block/sdg
SIET VIRTUAL-DISK 146cee20
Notice how the serial number has been pasted over the vendor+model at
index 1 instead of being added at the end.
In the former case:

firmware: search for third party or sysadmin supplied firmware updates
We currently search /lib/firmware and /lib/firmware/`uname -r` for firmware

separate package containing firmware. But these files cannot easily be
updated by third parties or sysadmins independently of that package.
This patch causes udev to also look for firmware files in an "updates"
directory, which is almost identical in purpose to the module-init-tools
"updates" directories insomuch as local changes can go in here and will
take preference over firmware supplied by any distribution.
