bench: Break large source file into smaller files

The bench-utils.c file started to have utilities that could stand
semantically under a separate category. Namely, verification is now at
bench-verify.c and progress report under bench-report.c.

bench: Ping target peer before starting timers

In some cases, the target peer may take some time before it finishes
with its initializations. Since we don't want to measure this idle time,
we send a ping request first and can start start the benchmark after we...

bench: Add --prefix option

The --prefix option allows the user to choose whatever prefix he/she
wants for the object names that will be generated.

This commit also cleans code that has to do with seeding and creating
object names. It also paves the way for the --objname option.

bench: Introduce new progress report and intervals

This commit renews the progress report that bench has by allowing to
report bandwidth results during benchmark.

Also, an additional functionality is that of report intervals. Report
intervals allow the user to choose exactly when progress report will be...

bench: Minor correction on seed validation

bench: Fix target to not include null termination.

Request of the target must not be null terminated. Remove null termination from
the requests constructed by peers.

bench: Fix issuing of read/write requests

Due to no initialization of struct bench, some "ifs" in the code would
show different behavior depending on the junk values they would check.
Now however, there is proper initialization of struct bench.

bench: Change prefixes of static functions

In this repo, a static helpder function is prefixed with "__". However,
some static helper functions in bench-utils.c where prefixed with a
single underscore ("_"), so we updated their names to be consistent with...

Style changes

Fix verification full mode

Add skeleton for verification in write path

Add partial support for verification

Adds an option to choose between verification modes:

1. meta: On this mode, we write our signature both at the start and the
end of the chunk size. It should be very fast and moderately safe,
due to the fact that corruptions happen it the chunk's edges....

Add support for seed values given by the user

A new option has been added (--seed) which allows the user to pre-define
the seed that he/she wants. This has the following effects:

• The target names are prefixed with the first 9 digits of the seed.
• LFSR produces a predictable sequence of "random" numbers

Fix incorrect reading of "insanity" parameter

Tweak performance of bench

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.

Fix flag handling of struct bench

Add utility functions to header file
