Automake 1.10.1 compat: AM_SILENT_RULES

Part of the automated testing involves building the source on Debian Lenny
which ships an ancient version of automake (1.10.1).  Historically, this
has caused a non-fatal warning about AM_SILENT_RULES not being defined.
But when the autogen.sh script was updated to use autoreconf the warning
became fatal.

  configure.ac:31: warning: macro `AM_SILENT_RULES' not found in library
  autoreconf: running: /usr/bin/autoconf --force
  configure.ac:34: error: possibly undefined macro: AM_SILENT_RULES
        If this token and others are legitimate, please use m4_pattern_allow.

To resolve this build issue the call to AM_SILENT_RULES has been wrapped
by m4_ifdef().  This prevents the macro from being expanded on platforms
where it's undefined.

Only require spl-devel-kmod = %{version}

Commit f6fb7651a0d05b357dc179cc4853263ce15da6ed introduced the idea
of working builds which work correctly.  However, because the zfs-kmod
depends on a specific 'spl-devel-kmod = {version}-%{release}' package
and the release component is unique the dependency is never satisfied.

This requires line was introduced to ensure the correct version of the
spl is always used.  In this context only the version number is required
so the release component has been dropped to satisfy the dependency.

Replace the ZFS_AC_META perl dependency with awk

The only remaining perl dependency is part of the ZFS_AC_META macro.
By eliminating this and replacing it with awk we can avoid the need
to pull in perl to rebuild the packages.

Add additional dependencies for DKMS package

For the DKMS package to successfully build the kernel-devel

Allow setting a lower ashift with -o ashift

Previous patches have allowed you to set an increased ashift to
avoid doing 512b IO with 4k sector devices.  However, it was not
possible to set the ashift lower than the reported physical sector
size even when a smaller logical size was supported.  In practice,
there are several cases where settong a lower ashift is useful:

* Most modern drives now correctly report their physical sector
  size as 4k.  This causes zfs to correctly default to using a 4k
  sector size (ashift=12).  However, for some usage models this
  new default ashift value causes an unacceptable increase in
  space usage.  Filesystems with many small files may see the
  total available space reduced to 30-40% which is unacceptable.

* When replacing a drive in an existing pool which was created
  with ashift=9 a modern 4k sector drive cannot be used.  The
  'zpool replace' command will issue an error that the new drive
  has an 'incompatible sector alignment'.  However, by allowing
  the ashift to be manual specified as smaller, non-optimal,
  value the device may still be safely used.
