9a9e74250d libflow: accommodate Macs 
As of today, macOS or OS X still does not implement
clock_nanosleep() according to this project:

5ac9551d87 libflow: avoid types size_t and ssize_t in libflow.h 
Those types are not included in libflow.h and
including them is overwhelming.

099eb7fd42 f3read: tighten assert() 
The last assert() in iterate_files() was doing an integer division
before comparing values, so there was potential for a bug going
silent due to the truncation fo the integer division.
This patch rewrite the test with a multiplication.

79cd2d66a2 libflow: rename fields and variables for generality 
The original libflow was written for f3write only, and
this was reflected in the name of fields and variables
throughout the code. This patch renames these fields and
variables to reflect the fact that libflow will eventually
support f3write AND f3read.

791acdc326 libflow: do measurements over multiple files 
With really fast drives (i.e. >1GB/s), f3write needs to
write multiple files before a measurement can be made.
This patch enhances the flow library to deal with such fast drives.

5846f9dbb1 f3probe: report unexpected error codes in read_all() 
No unexpected error code should happen in read_all(), but,
if it does, f3probe will report them before aborting.

2766edd4be f3write: adopt write_all() from libdevs.c 
The file system HFS (i.e. "OS X Extended (Journaled)") of
macOS 10.11 may return a number of partial write()'s before
the file system is full.

This POSIX-permited, but unusual behavior was frist reported here:

0b8c973c4c f3write: improve measurement of write speed 
According to issue #102, calls to fdatasync() might take
a long time (.e.g. 3s or 4s) and distort the measurement of
the average write speed. This patch addresses it by only updating
the measurements when delays are within a tolerance.

3ab5bad85c libdevs: bring back missing ‘const’ specifier 
Commit 7ff9fad37a32 ("libdevs: fix compiler warning") fixed the warning
by removing duplicate ‘const’ specifier.
The original intent of two ‘const’ specifiers, was most likely to make
non-mutable both: the ‘ftype_to_name‘ array itself and its elements,
so bring back the second ‘const’, but in the correct place this time,
i.e. after ‘*‘.
