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.

We should not put a 4k maxpathlen buffer on the stack, instead
locate it to the heap. Even in user space we run ztest with 8K
stacks to verify correctness

This is a portability change which removes the dependence of the Solaris
thread library. All locations where Solaris thread API was used before
have been replaced with equivilant Solaris kernel style thread calls.
In user space the kernel style threading API is implemented in term of
the portable pthreads library. This includes all threads, mutexs,
condition variables, reader/writer locks, and taskqs.

Do not use zmod.h in userspace.
This has also been filed with the ZFS team. It makes the userspace
libzpool code use the zlib API, instead of the Solaris-only and
non-standard zmod.h. The zlib API is almost identical and is a de
facto standard, so this is a no-brainer.

1) In vn_open(), if fstat64() returned an error, the real errno
was being obscured by calling close().
2) Add error handling for both pwrite64() calls in vn_rdwr().

Resolve issues uncovered by -D_FORTIFY_SOURCE=2, the default redhat
macro's file adds this option to the cflags. This causes warnings
of the following type designed to keep the developer honest:
warning: ignoring return value of 'foo', declared
with attribute warn_unused_result
The short term fix is to wrap these calls in VERIFY() to check the
return code. The code was already assusing these would never fail.
