Increment completed requests of insane timers

Even if a timer is not used for a benchmark, we need to increment its
completed requests since these are needed to calculate how many requests
are left etc.

Implement most semi-finished functionalities

Summary of new functionalities:

  • Add support for 4 different xseg operations (read, write, info,
    delete).
  • Add support for random I/O patterns with a fast Galois LFSR.
  • Add insanity levels in timers, which allow the user to exclude obscure...

Add an LFSR PRNG for bench

The PRNG introduced by this commit is a Galois-XNOR LFSR, which can
generate unique pseudorandom numbers. Also, seeded with the same
seed, it will produce the same sequence.

This implementation is driven by the needs of XSEG for a blazing fast...

Design the program's skeleton for new features

Bench peer must be able to test all xseg operations in a synchronous or
asynchronous way. Also, it must have a validation mode to sanity-check
if xseg requests are issued properly. Most of the above are present in...
