This changes the API for visor_memregion_create() to require a
pre-allocated struct memregion. Embedding this in struct channel
avoids a layer of additional kmalloc()'s and error checks.

The error handling in this function was broken and while looking at that
I noticed that the whole function was in need of cleanup. This patch
fixes the error handling, specifically
if (!p) {
visorchannel_destroy(p);
channel = NULL;
}
and does a lot of cleanup. I also verified that the called functions
returned correct errors, and that led to a change in
visor_memregion_resize(), visorchannel_destroy() and
visor_memregion_destroy().

visorbus_private.h contains code that is called from visorbus into the
visorchipset code. Now that the visorchipset code has been brought into
the visorbus directory, many of the declarations are not necessary and
can be cleaned up.
TODO: PARSER_WHICH_STRING enum only has one member used
(PARSERSTRING_NAME).
TODO: crash_obj_type appears to be unnecessary in the overall scheme of

Move visorchipset_main.c and visorchipset.h to visorbus/visorchipset.c and
visorbus/visorbus_private.h. This leaves an empty visorchipset directory
which can also be destroyed.
As a result of this patch the visorchipset init code now calls the
visorbus_init() directly. Similarily the visorchipset exit code now
cleans up by calling visorbus_exit().
No other functional changes were made.
