1fd621ff6d minor man page update 
regarding advanced parameter `tlen`
which was recently changed.
`0` in association with `ZSTD_fast` now means "normal fast mode".

6a9b41b731 create command --fast[=#] 
access negative compression levels from command line
for both compression and benchmark modes.

also : ensure proper propagation of parameters
through ZSTD_compress_generic() interface.

added relevant cli tests.

9f8ed23b5b bumped version number to v1.3.4 
also added a paragraph on using compression level with training mode
as this is a recurrent question (see for example #1004)

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#.

3a60efd3a9 policy change : ZSTDMT automatically caps nbThreads to ZSTDMT_NBTHREADS_MAX (#760) 
Previously, ZSTDMT would refuse to create the compressor.
Also : increased ZSTDMT_NBTHREADS_MAX to 256,
updated doc,
and added relevant test

96aa3019b2 changed advanced commands --maxdict= and --dictID= 
now works with the `=` variant, which is the recommended one.
Old variant `--dictID #` still works, for compatibility with existing scripts.
Long term objective is to remove the old variant..
