Fix ringbuffer creation on sparc
...
On the first call to qb_rb_open() we try using a number of
page sizes. This because the system might have CONFIG_HUGETLB_PAGE_SIZE
defined in their kernel. So even though sysconf() returns 2K or 4K
some arch's mmap() require alignment on these boundaries.

This ringbuffer is usable across processes.
the point is to use this for IPC to provide async

flow control.
This still needs a bit of clean up, but committing now
for feedback and as it is quite functional.
