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...

Alpha release of bench peer

On this release, the bench peer can measure the total elapsed time
of the benchmark. TODO:

  • Allow bench peer to be multi-threaded.
  • Adjust benchmarking precision, by eliminating or including more
    trivial timers.
  • Measure mean time, standard deviation of requests.
