f3probe: avoid hanging before the second reset

f3probe was writing too many blocks between
the first and the second reset due to
a poor estimate of the writing and reseting times.

Bump next version to 4.0

Given that support for FreeBSD was added,
the next release will no longer be 3.1, but 4.0.

f3read: fix for Windows/Cygwin

Windows requires that the file descriptor passed to fdatasync(2)
to be writable.

Tom Hall reported the issue and proposed the solution.

Increment version to 2.2

Report version and copyright in help message

This was added mainly to help users to identify
the version they have installed.

Added a very simple Makefile

Version 1.1.3

Fixed some warning issued by GCC when compiling f3read.c on 64bits machines.
Nicolai Abruzzese was the first one to report this issue.

f3read.c: In function 'report':
f3read.c:126: warning: format '%llu' expects type 'long long unsigned int', but argument 5 has type 'uint64_t'
f3read.c: In function 'iterate_path':

f3read.c:166: warning: format '%llu' expects type 'long long unsigned int', but argument 5 has type 'uint64_t'

Version 1.1.2

Handled an I/O error reported by Misha Aizatulin.
