c233bdbaee Increase maximum window size 
* Maximum window size in 32-bit mode is 1GB, since allocations for 2GB fail
  on my Mac.
* Maximum window size in 64-bit mode is 2GB, since that is the largest
  power of 2 that works with the overflow prevention.
* Allow `--long=windowLog` to set the window log, along with
  `--zstd=wlog=#`. These options also set the window size during
  decompression, but don't override `--memory=#` if it is set.
* Present a helpful error message when the window size is too large during
  decompression.
* The long range matcher defaults to a hash log 7 less than the window log,
  which keeps it at 20 for window log 27.
* Keep the default long range matcher window size and the default maximum
  window size at 27 for the API and CLI.
* Add tests that use the maximum window size and hash size for compression
  and decompression.

086b9597d9 added ability to split input files for dictionary training 
using command -B#
This is the same behavior as benchmark module,
which can also split input into arbitrary size blocks, using -B#.

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.
