838d51d296 Fix write_lseek_blockwise for in the middle of sector case. 
See unit test write_lseek_blockwise(bsize=512, offset=1, length=1).

The test tries to modify single byte at offset 1 of device with
bsize=512.

e2845bc032 Zero length lseek blockwise i/o should return zero. 
Note that both functions perform seek operations aligned to sector
boundary if possible before returning.

Unaligned input offset gets aligned on first preceding sector
boundary.

869767a5cf Move general i/o code to stand-alone utility file. 
Get rid of internal library stuff linked to the utilities.
Also rename 'count' param to 'length' clarifying handling
of the parameter internally.
