Porting Notes:
dbuf_free_range():
- reduce stack usage using kmem_alloc()
- the sorted AVL tree will handle the spill block case correctly
without all the special handling in the for() loop

In the original implementation of the SPL wrappers were provided
for module initialization and cleanup. This was done to abstract
away any compatibility code which might be needed for the SPL.
As it turned out the only significant compatibility issue was that
the default pwd during module load differed under Illumos and Linux.
Since this is such as minor thing and the wrappers complicate the
code they are being retired.

Inclusion of SPL compatibility headers was moved out of the public
header sys/types.h to avoid conflicts with external packages. Include a
few compatiblity headers explicitly to cope with that change. Also,
sort some linux-specific inclusions alphabetically.

Use the standard Linux MODULE_VERSION macro to expose the installed
zavl, znvpair, zunicode, zcommon, zfs, and zpios module versions.
This will also automatically add a checksum of the .c files and
headers in "srcversion". See:
/sys/module/zavl/version
/sys/module/zavl/srcversion
/sys/module/znvpair/version
/sys/module/znvpair/srcversion
/sys/module/zunicode/version

/sys/module/zcommon/version
