I first noticed this while working on my NBD driver. While this
doesn't completely batch up large I/O, it sure makes 64-bit access
more efficient.

ios: Drop Position column from .info ios
ios: Pass offset to low-level macros.
ios: Prove we don't need seek.
ios: Drop unused seek/tell callbacks.
ios: Change from getchar to pread device interface.
ios: Utilize buffer reads.
ios: Utilize buffer writes.
I went thru the patch series and, in my opinion, it is good for master.
The pread/pwrite like interface is definitely better than the getc/putc.
However, I would like to hear Egeyar's opinion about it, as she wrote
the integer read/write code in ios.c, and therefore is in a better
position than me to do a review in that area.
