Fix wrong accouning of zone bytes

The idea here is that I wanted to line up my zones to start at 1M
boundaries across the disk by writing 1k and skipping the next 1023k.
In practice I don't get the alignment because of an extra initial I/O.
I get an iolog that looks like
fio version 2 iolog
/dev/cciss/c0d1 add
/dev/cciss/c0d1 open
/dev/cciss/c0d1 read 0 1024

/dev/cciss/c0d1 read
2098176 1024
There's a read that I don't expect in that log, namely the read starting
at byte 1024. Because that read is there, the disk zones get offset by
one block. I expected output like
fio version 2 iolog
/dev/cciss/c0d1 add
/dev/cciss/c0d1 open
/dev/cciss/c0d1 read 0 1024

The problem is due to the fact that fio account zone_bytes when the IO
completes, which is clearly not correct for io depth > 1. So move the
accounting to when we fill the io_u instead.

Add support for 'bssplit' option, fine grained block size contrl
From the HOWTO addition:
bssplit=str Sometimes you want even finer grained control of the
block sizes issued, not just an even split between them.
This option allows you to weight various block sizes,
so that you are able to define a specific amount of
block sizes issued. The format for this option is:
bssplit=blocksize/percentage:blocksize/percentage
for as many block sizes as needed. So if you want to define
a workload that has 50% 64k blocks, 10% 4k blocks, and
40% 32k blocks, you would write:
bssplit=4k/10:64k/50:32k/40
Ordering does not matter. If the percentage is left blank,
fio will fill in the remaining values evenly. So a bssplit
option like this one:
bssplit=4k/50:1k/:32k/
would have 50% 4k ios, and 25% 1k and 32k ios. The percentages
always add up to 100, if bssplit is given a range that adds
up to more, it will error out.

Fix failure in opening files with O_NOATIME
If we try to open a file with O_NOATIME and it fails, turn off
O_NOATIME and try again. This occurs if the user does not own
the file and is unprivileged.

Seperate ioprio value from setting
Newer kernels allow passing a value of '0' for resetting ioprio,
and our check for if (td->ioprio) doesn't allow passing a value of
0 into sys_ioprio_set(). So seperate the setting from the value by
adding a ->ioprio_set bool.

splice: fix problem with current mainline kernels
splice was updated to work well with the newer vmsplice patches,
where we don't have to copy data at all. But that broke the
regular vmsplice that copies data, which is all the mainline kernel
still support.
Fix that up, so we do appropriate fallbacks. Fixes the problem
