e2a59bc08d libflow: avoid fdatasync() and posix_fadvise() 
This patch moves calls to fdatasync() and posix_fadvise() out of
libflow as one more step to generalize libflow.

14b35b5bc6 f3write: avoid unnecessary calls to measure() 
This patch is only meant to have a simpler calling pattern of
libflow since it'll be generalized down the line.

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.

b1ab05c280 f3write: move flow code to a new library (libflow)

reuse it in f3read.

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.

c9eee71ee9 f3write: add a backup speed measurement 
If the drive is too fast for the measument of the flow algorithm,
this patch uses a coarse approximation of the writing speed.

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.

libdevs: bring back missing ‘const’ specifier

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 ‘*‘.

It'd be great to have a solution for all platforms, but, for now,
one has to uncomment lines on Makefile to work on some platforms.
