Add support for runtime log compression
If log_compression=64M is specified, fio will "bite" off chunks of
the IO logs and runtime compress them with zlib. This can greatly
reduce the amount of memory required to do iops/bw/lat logging of
a run, at the cost of using some background CPU for the compression.

Pre-load and sort random blocks for pure read verify workloads
If fio is run with a write phase before a read phase and the
IO type is random, the end read verify phase will get sorted
blocks to read back. But if fio is asked to verify something
that was previously randomly written, it will generate the
same random offsets in random order and verify those. This is
usually much slower than a sorted read back.
So add a verifysort_nr option that allows the user to specify
a number of random offsets to pre-generate and sort, before
reading them and verifying the contents. This greatly speeds
up pure read verify workloads.
Default to 1024, and put a max of 64K entries on the option.
We do a merge list sort on the entries, so we don't want a
huge amount of backlog.

Allow fio headers to be included by a C++ build
The attached patch allows fio 1.17.2 header files to be included by a
C++ build without generating compile errors due to C-ism.
Specifically, due to:
- use of the keyword "new" as a parameter name
- a cast of a return value to void *, when the function signature
returns a different type
