We need dependent packages to be able to include spl_config.h so they
can leverage the configure checks the SPL has done. This is important
because several of the spl headers need the results of these checks to
work properly. Unfortunately, the autoheader build product is always
private to a particular build and defined certain common things.
(PACKAGE, VERSION, etc). This prevents other packages which also use
autoheader from being include because the definitions conflict. To
avoid this problem the SPL build system leverage AH_BOTTOM to include
a spl_unconfig.h at the botton of the autoheader build product. This
custom include undefs all known shared symbols to prevent the confict.
This does however mean that those definition are also not availble
to the SPL package either. The SPL package therefore uses the
equivilant SPL_META_* definitions.

* spl-07-kmem-cleanup.patch
This moves all the debugging code from sys/kmem.h to spl-kmem.c, because
the huge macros were hard to debug and were bloating functions that
allocated memory. I also fixed some other minor problems, including
32-bit fixes and a reported memory leak which was just due to using the
wrong free function.

spl-05-div64.patch
This is a much less intrusive fix for undefined 64-bit division symbols
when compiling the DMU in 32-bit kernels.
* spl-06-atomic64.patch
This is a workaround for 32-bit kernels that don't have atomic64_t.
