919568a223 Don't use floor() in _bitset_with_random_bits
Use _even_rand() function instead of floor() in _bitset_with_random_bits().
floor() function is missing in dietlibc (on architectures other than x86).
Moreover using floor() to clip rand results does not assure even result
distribution. _even_rand() uses integer arithmetic only and is designed to
return evenly distributed results.

> Looks OK to me. It took a while to decipher what is the exact meaning of
> the loop in _even_rand (to a non-pseudorandomness-expert) but I am
> fairly comfortable with it now. If I understand this correctly, it
> rejects numbers that come from an "incomplete" slice of the RAND_MAX
> space (considering the number space [0, RAND_MAX] is divided into some
> "max"-sized slices and at most a single smaller slice, between [n*max,
> RAND_MAX] for suitable n -- numbers from this last slice are discarded
> because they could distort the distribution in favour of smaller
> numbers).

e76736cf55 Based on auto-detection or user requested cluster managers for clvmd,
set appropriate Required-Start and Required-Stop at configure time.

Reorder the checks for user selected cluster managers to match auto
detected ones, to be consistent in the output.

Add special case for qdiskd that´s started after cman/lock_gulmd for
RHEL-4/RHEL-5.

establish DEFAULT_DATA_ALIGNMENT.  Again, 0=64KiB, 1=1MiB, 2=2MiB

2db34bd266 INSTALL rules updates
Patch is inspired by Debian's extra patch.

- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target
- prints whole 'install' command during installation instead of less
  informative "Installing  $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets

4b8340327c As lcov module is not installed with GD.pm dependency we need
to check for presence of this module and avoid using --frames
option for genhtml in this case.

940c32c5dd Strictly require libudev if udev_sync is used.
This prevents some confusion when libudev was not found so udev_sync was disabled
automatically. Configure was successful though giving only a tiny warning.

Also, if "dmsetup udevcreatecookie" is used, never return 0x000000 as a result if
udev is not running and keep the output blank.

5451f79f55 This patch add SELINUX_LIBS and STATIC_LIBS variables.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.

Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.

SELinux header check moved to the SELinux test code.

f9d1b67e86 Readline linking update
Modify linking of readline library. Create new  substituted varible
READLINE_LIBS - readline library is linked ONLY with tools that really use
it - i.e. lvm. (Static lvm does not use readlin).
Previous behaviour put this library into the variable LIBS and thus
linked it with all created object files of lvm project (i.e. plugins...).

READLINE detection is simplified.

Termcap library is linked in only if readline library doesn't have its own
dependency (i.e. old distributions).

5077a1bb83 Show a warning message when libudev not found and we're using --enable-udev_sync.

and we will consider that udev is not running at all.
