Basic compilation of the bulk of zfs_znode.c has been enabled. After
much consideration it was decided to convert the existing vnode based
interfaces to more friendly Linux interfaces. The following commits
will systematically replace update the requiter interfaces. There
are of course pros and cons to this decision.
Pros:
* This simplifies intergration with Linux in the long term. There is
no longer any need to manage vnodes which are a foreign concept to
the Linux VFS.
* Improved long term maintainability.
* Minor performance improvements by removing vnode overhead.
Cons:
* Added work in the short term to modify multiple ZFS interfaces.
* Harder to pull in changes if we ever see any new code from Solaris.
* Mixed Solaris and Linux interfaces in some ZFS code.
This topic branch contains all the changes needed to integrate the user
side zfs tools with Linux style devices. Primarily this includes fixing
up the Solaris libefi library to be Linux friendly, and integrating with
the libblkid library which is provided by e2fsprogs.

Fix non-c90 compliant code, for the most part these changes
simply deal with where a particular variable is declared.
Under c90 it must alway be done at the very start of a block.
