check event size for version 1
If we ever increase the event struct size, then we
will need to handle multiple event sizes, so let's
define the current event size and check for that
so we remember to fix it up when (if ever) we need
to change things.

use right event size for read()
In order to be compatible with future size increases of
the kernel's rfkill structure, userspace should only
read as much as it expects -- the kernel will truncate
the event read if necessary, which is the way we plan
to have compatibility between different versions, should
they ever be necessary.
Thus, the userspace tool needs to use the exact event
size for a read().
If the userspace tool is ever compiled with a newer
kernel then it will need to be adjusted to work with
older kernels, however.

build-sys: reverse shlibs installation
[kzak@redhat.com:
Unfortunately, libtool does not provide a way how to install real
libraries to /lib and devel libs (symlinks) to /usr/lib. We have
to use install hooks to move these files.
Currently we install to /lib and move devel files to /usr/lib. This
concept is wrong, because the libdir= in .la libtool files must to
match with the place where we install the devel .so libs. It means we
have to install everything to /usr/lib and then move (by install hook)
the real .so libs to /lib.
This change is necessary to fix "make install", otherwise the install
process will not work in clean change root. ]

libuuid: Don't run uuidd if it would fail due to permission problems
Some distributions don't like installing uuidd setuid or setgid. So
if the setuid or setigid bit is not set with uuidd, and the current
process does not have write access to the UUIDD work directory, don't
try running uuidd, since it won't work properly.
libuuid, uuidd: Avoid infinite loop while reading from the socket fd
If for some reason the uuidd daemon or the process calling uuidd
exited unexpectely, the read_all() function would end up looping
forever, either in uuidd or in libuuid. Fix this terminating the loop
if no data can be read after five tries to read from the file
descriptor.
uuidd: Avoid closing the server socket when calling create_daemon()
In the event that file descriptors 0-2 are closed when uuidd is
started, the server socket could be created as a file descriptor that
will get closed when create_daemon() tries detaching the uuidd daemon
from its controlling tty. Avoid this case by using dup(2).

libuuid: Make sure fd's 0, 1, and 2 are valid before exec'ing uuidd
When closing all of the file descriptors before starting uuidd, make
sure file descriptors 0, 1, and 2 are reserved by opening /dev/null.
This prevents strange bugs caused by assumptions regarding file
descriptors <= 2 as being special.

libuuid: fix $libdir in uuid.pc
The -L<dir> gcc option is for directories to be searched for .so/.a

The side effect is that pkg-config does not return -L with standard
system directories (so make(1) output is more readable and shorter).

raw: Use the RAW_SETBIND ioctl without stat'ing the raw# file
The in-kernel ioctl code creates a raw# device on-demand. udev will create
the /dev/raw/raw# file when the device is created automatically.
The current raw userspace code wants to stat the file before using it,
which is unnecessary for setting up the raw device.
This patch stats the file only when query() is called as a singleton, and
it's doubtful it's needed even there. I modified as little code as I could,
though.

mount: move MS_{PROPAGATION,BIND,MOVE} detection
The previous commit does not properly fix the problem with "none"
fstype and MS_{PROPAGATION,BIND,MOVE} flags. The real fstype has to
be replaced with "none" before we try to use /sbin/mount.<type>
helper.
Allow users to set the "none" class on processes. Using the
none class has the distict advantage that the io priority
is inherited from the cpu nice level. Update the man page
to reflect the change.
