d3364aa39e improve benchmark measurement for small inputs 
by invoking time() once per batch, instead of once per compression / decompression.
Batch is dynamically resized so that each round lasts approximately 1 second.

Also : increases time accuracy to nanosecond

31293330d0 It's still necessary to check PLATFORM_POSIX_VERSION for clock_gettime() 
glibc/uclibc is not enough

e46194bbf9 fix #911 : changed detection macro for clock_gettime() 
The new macro might be a bit too restrictive.
Systems which do not support new test will simply default to <time.h>'s `clock_t clock()`,
suffering lesser benchmark accuracy.
Should it matter, the detection macro will have to be upgraded.

d898fb7ba6 bench: added cli command -S to benchmark multiple files separately 
Currently, all files are joined by default,
they are compressed separately but benchmarked together,
providing a single final result.

Benchmarking files separately make it possible to accurately measure difference for each file.
This is expected to be useful while tuning optimal parser.

18b795374a UTIL_getFileSize() returns UTIL_FILESIZE_UNKNOWN on failure 
UTIL_getFileSize() used to return zero on failure.
This made it impossible to distinguish a failure from a genuine empty file.
Both cases where coalesced.

Adding UTIL_FILESIZE_UNKNOWN constant has many consequences on user code,
since in many places, the `0` was assumed to mean "error".
This is no longer the case, and the error code must be actively checked.

8f26dc3f9c blindfix for Visual 
LARGE_INTEGER is not an integer :
https://msdn.microsoft.com/en-us/library/windows/desktop/aa383713(v=vs.85).aspx

Do not take any risk with the structure definition :
use int init = 0; like Mac code

c95c0c9725 modified util::time API 
for easier invocation.
- no longer expose frequency timer :
it's either useless, or stored internally in a static variable (init is only necessary once).
- UTIL_getTime() provides result by function return.

6ab4d5e904 [bench] Use higher resolution timer on POSIX 
The timer used was only accurate up to 0.01 seconds. This timer is accurate up to 1 ns.
It is a monotonic timer that measures the real time difference, not on CPU time.
