bench: Track elapsed time for each timer

Also, create two functions timespecsub() and timespecadd() that can
subtract and add two timespec structs.

bench: Improve benchmark results

Changes include:

  • Show the average request latency when run with insanity "eccentric"
  • Don't show bandwidth results for info/delete requests

Add a fallback clock for portability reasons

Refactor struct bench and appropriate code paths

Changes:

1. Move flag values (such as pattern, insanity, verify) in a specific
bit-field.
2. Create a struct req_status where the status of requests will be
stored.
3. Tidy up code.

Rationale:

1. For parameters that can have only a few different values, it's an...

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...

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.

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...
