pagingtest: switch to advising random accesses
Switch to using madvise(MADV_RANDOM) and posix_fadvise(POSIX_FADV_RANDOM)
to disable caching as opposed to reading the file backwards, which still
went through some caching.
Measured a 80% drop in worst case performance after switching.

Add paging test
Add a system paging test that measures the following things:
- mmap and munmap a file
- page a file and and out of memory
- thrash the page cache by bringing in more pages than the system can hold in RAM
