OK, here is my attempt at making it a bit more readable:

- move all of the details on offsets, lengths and buffers into a 
single function instead of doing these operation from multiple places

- use a bottom up approach - try to avoid details in the high level functions, 
introduce them gradually as you go deeper in the function call stack

I've attached both the patch and a full excerpt - it might be easier to 
comment on it  this way.

I've minimally tested the patch, no obvious functional or performance problems 
were found.
