Richard Yao 60e9f69c97 Make directory into which mount.zfs is installed configurable
Installing outside of the prefix is not permissible under Gentoo Prefix.
The package manager will cause the installation process to fail if/when
it sees this. I could script a workaround inside the ebuild, but it
seemed to make more sense to make this more configurable.

Matthew Thode 11b9ec23b9 Add full SELinux support
Four new dataset properties have been added to support SELinux.  They
are 'context', 'fscontext', 'defcontext' and 'rootcontext' which map
directly to the context options described in mount(8).  When one of
these properties is set to something other than 'none'.  That string
will be passed verbatim as a mount option for the given context when
the filesystem is mounted.

For example, if you wanted the rootcontext for a filesystem to be set
to 'system_u:object_r:fs_t' you would set the property as follows:

  $ zfs set rootcontext="system_u:object_r:fs_t" storage-pool/media

This will ensure the filesystem is automatically mounted with that
rootcontext.  It is equivalent to manually specifying the rootcontext
with the -o option like this:

  $ zfs mount -o rootcontext=system_u:object_r:fs_t storage-pool/media

By default all four contexts are set to 'none'.  Further information
on SELinux contexts is detailed in mount(8) and selinux(8) man pages.

Maximilian Mehnert 539defc873 Add missing libzfs_core to Makefiles
On some platforms symbols provided by libzfs_core and used by
libzfs were not available to the linker.  To avoid this issue
libzfs_core has been added to the list of required libraries
when building utilities which depend on libzfs.  This should
have been handled properly by libtool and it's still not
entirely clear why it wasn't on all platforms.

Richard Yao 31fc19399e Generate libraries with correct DT_NEEDED entries
Libraries that depend on other libraries should list them in ELF's
DT_NEEDED field so that programs linking to them do not need to specify
those libraries unless they depend on them as well. This is not the case
in the current code and the consequence is that anything that needs a
library must know its dependencies. This is fragile and caused GRUB2's
configure script to break when a dependency was added on libblkid in
libzfs.

This resolves that problem by using LIBADD/LDADD to specify libraries in
Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED
entries are generated and prevents GRUB2's configure script from
breaking in the presence of a libblkid dependency. This also removes
unneeded dependencies from various files.

Etienne Dechamps ba7dbeb22e Add libnvpair to mount_zfs dependencies
Commit e6f290535c added libzpool to
the mount_zfs dependencies.  This brought in the nvpair symbols
which are used by libzpool.  To resolve this include the libnvpair
library for mount_zfs even though mount_zfs doesn't directly
require any of these symbols.

Etienne Dechamps e6f290535c Fix mount_zfs dependency on libzpool.
mount_zfs depends on libzpool for zfs_prop_written since
330d06f90d. Unfortunately, the Makefile
for mount_zfs has not been modified to reflect this. As a result,
libtool doesn't know about the dependency, which may result in the wrong
libzpool being used during the build (e.g. the libzpool from the system
instead of the libzpool from the build directory).

This patch adds the dependency to fix the issue.

Darik Horn 750562833f Combine libraries: spl, avl, efi, share, unicode.
These libraries, which are an artifact of the ZoL development
process, conflict with packages that are already in distribution:

  * libspl: SPL Programming Language
  * libavl: AVL for Linux
  * libefi: GRUB

And these libraries are potential conflicts:

  * libshare: the Linux Mount Manager
  * libunicode: Perl and Python

Recompose these five ZoL components into the four libraries that are
conventionally provided by Solaris and FreeBSD systems:

  + libnvpair
  + libuutil
  + libzpool
  + libzfs

This change resolves the name conflict, makes ZoL more compatible
with existing software that uses autotools to detect ZFS, and allows
pkg-zfs to better reflect the official Debian kFreeBSD packaging.

Darik Horn afd7da0ce7 Add LIBSELINUX to mount_zfs_LDFLAGS.
Regenerating the autotools configuration on Debian and Ubuntu systems
causes compilation to fail with this error message:

  cmd/mount_zfs/../../cmd/mount_zfs/mount_zfs.c:403:
    undefined reference to `is_selinux_enabled'

In the automake template, set "mount_zfs_LDFLAGS = ... $(LIBSELINUX)"
so that the /sbin/mount.zfs utility is linked to libselinux.

Brian Behlendorf 716895b161 Fix 'LDFLAGS=-Wl,--as-needed' build error
Compiling with 'LDFLAGS=-Wl,--as-needed' exposed the fact that
there were some library linking problems introduced by mount_zfs.
In particular, the libzfs library does use nvpair symbols, and
mount_zfs contains no dependencies on libzpool.

Brian Behlendorf d53368f675 Fix mount helper
Several issues related to strange mount/umount behavior were reported
and this commit should address most of them.  The original idea was
to put in place a zfs mount helper (mount.zfs).  This helper is used
to enforce 'legacy' mount behavior, and perform any extra mount argument
processing (selinux, zfsutil, etc).  This helper wasn't ready for the
0.6.0-rc1 release but with this change it's functional but needs to
extensively tested.

This change addresses the following open issues.
