Cleanup the --enable-debug-* configure options, this has been pending for quite some time and I am glad I finally got to it. To summerize: 1) All SPL_AC_DEBUG_* macros were updated to be a more autoconf friendly. This mainly involved shift to the GNU approved usage of AC_ARG_ENABLE and ensuring AS_IF is used rather than directly using an if [ test ] construct. 2) --enable-debug-kmem=yes by default. This simply enabled keeping a running tally of total memory allocated and freed and reporting a memory leak if there was one at module unload. Additionally, it ensure /proc/spl/kmem/slab will exist by default which is handy. The overhead is low for this and it should not impact performance. 3) --enable-debug-kmem-tracking=no by default. This option was added to provide a configure option to enable to detailed memory allocation tracking. This support was always there but you had to know where to turn it on. By default this support is disabled because it is known to badly hurt performence, however it is invaluable when chasing a memory leak. 4) --enable-debug-kstat removed. After further reflection I can't see why you would ever really want to turn this support off. It is now always on which had the nice side effect of simplifying the proc handling code in spl-proc.c. We can now always assume the top level directory will be there. 5) --enable-debug-callb removed. This never really did anything, it was put in provisionally because it might have been needed. It turns out it was not so I am just removing it to prevent confusion.
