With a bit of manual rereading and thinking I came to conclusion
that users will most likely fetch same data over and over again.
Advicing to kernel to keep pages into cache seems to be correct
thing to do.

The eprintf removed and replaced with err & warn. Option parsing
no longer tries to find missing optargs, which are getopts should
notice. Few complier warnings got to be removed as well. Finally
the commments will no longer exceed standard terminal width.

Code blocks to more common first order. Also couple checks got to
be refactored next to section where update happens, that will
reduce unnecessary checking.

The xml output does not use output file as all other outputs, it
has sections here and there while everything is supposed to be in
output.c, and finally the unnecessary field analysis loop made
program about 20% slower when xml was not asked.
