88ae51acb3 Multi-OS support for --list detecting stream input 
IS_CONSOLE stolen wholesale from Options.cpp
not sure if i should have extracted that code for DRY-ness
tested in OSX and functionality seems appropriate

209df52ba2 Changed nbThreads for nbWorkers 
This makes it easier to explain that nbWorkers=0 --> single-threaded mode,
while nbWorkers=1 --> asynchronous mode (one mode thread on top of the "main" caller thread).
No need for an additional asynchronous mode flag.
nbWorkers>=2 works the same as nbThreads>=2 previously.

394eec697b Introduce ZSTD_getFrameProgression() 
Produces 3 statistics for ongoing frame compression :
- ingested
- consumed (effectively compressed)
- produced

Ingested can be larger than consumed due to buffering effect.

For the time being, this patch mostly fixes the % ratio issue,
since it computes consumed / produced,
instead of ingested / produced.

That being said, update is not "smooth",
because on a slow enough setting,
fileio spends most of its time waiting for a worker to complete its job.

This could be improved thanks to more granular flushing
i.e. start flushing before ongoing job is fully completed.

3e1e57db27 fix fileio progression status update 
The compression % is no longer correct,
since it's no longer possible to make direct correlation
between nb bytes read and nb bytes written
due to large internal buffer inside CCtx
(exacerbated with --long).

The current "fix" is to no longer display the %.

A more complex solution will have to count exactly how much data has been consumed and compressed internally, within CCtx buffers.

10c213761a cli: fix for no-MT mode 
when cli is compiled without MT support,
invoking ZSTD_p_nonBlockingMode result in an error code.

This patch only sets ZSTD_p_nonBlockingMode when ZSTD_MULTITHREAD is set, meaning there is MT support.

The error code could also be intentionnally ignored (there is no side effect).

1dba98d563 introduced parameter ZSTD_p_nonBlockingMode 
This new parameter makes it possible to call
streaming ZSTDMT with a single thread set
which is non blocking.

It makes it possible for the main thread to do other tasks in parallel
while the worker thread does compression.
Typically, for zstd cli, it means it can do I/O stuff.

Applied within fileio.c, this patch provides non-negligible gains during compression.

Tested on my laptop, with enwik9 (1000000000 bytes) : time zstd -f enwik9

With traditional single-thread blocking mode :
real    0m9.557s
user    0m8.861s
sys     0m0.538s

With new single-worker non blocking mode :
real    0m7.938s
user    0m8.049s
sys     0m0.514s

=> 20% faster

5432ef6921 fixes adaptation on srcSize 
This patch restores capability for each file to receive adapted compression parameters depending on its size.

The bug breaking this feature was relatively silly :
setting a parameter with a value "0" is supposed to be a no-op.
Unfortunately, it would pin down compression parameters as if they were manually set,
preventing later automatic adaptation.

Unfortunately, I'm currently short of a test case that could check this situation and trigger an error.
Compression parameters selection between tableID 0,1,2,3 is largely internal,
leaving no trace to outside world, not even in frame header.

baff9dd15e Fix LZ4 Compression Buffer Overflow 
Fixes issue where, when `zstd --format=lz4` is fed an input larger than 128KB,
the read overruns the input buffer. This changes Zstd to use LZ4 with chained
64KB blocks. This is technically a breaking change in that some third party
LZ4 implementations may not support linked blocks. However, progress should not
be allowed to be stopped by such petty concerns as backwards compatibility!

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.

8afb151c9b cli: fixed wrong initialization in MT mode 
It's not good to mix old and new API
ZSTD_resetCStream() doesn't just set pledgedSrcSize :
it also sets the CCtx for a single thread compression.

Problem is, when 2+ threads are defined in cctx->requestedParams,
ZSTD_compress_generic() will want to start MT compression,
since initialization is supposed to have already happened (thanks to ZSTD_resetCStream())
except that the underlying ZSTDMT_CCtx* object is not created,
resulting in a segfault.

This is an invalid construction
(correct one is to use ZSTD_CCtx_setPledgedSrcSize()).
I haven't found a nice way to mitigate this impact if someone makes the same mistake.

At some point, removing the old API to keep only the new API within fileio.c will limit these risks.

fbd5ab7027 minor fix : no longer use fake srcSize during resource creation 
srcSize is read and provided at each file, not at resource creation.

It works fine by now.

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.

31533bacce Changed ZSTD_createCDict_advanced() 
It now only uses compressionParameters as argument.
It produces many changes throughout user code,
though hopefully they tend to be simple :
just provide the cParams part from existing ZSTD_parameters.

Some programs might depend on ZSTD_createCDict_advanced() to pass frame parameters.
This change will force them to revisit this strategy and fix it,
since frame parameters are effectively silently ignored in current version.

5d9b894e46 Fixed status display for zstdmt 
There is a large buffering effect when using zstdmt in MT mode.
Consequently, data is read first, pushed to workers,
and only later will the compressed result come out.
That means there is no longer immediate correlation
between amount of data read, and amount of data written.

This patch disables the displaying of % compression
when multi-threading is enabled.

It adds the displaying of total size when it can be determined
(it usually can be determined for files, but not for stdin)
so the user has a sense of "how far from the end" the compression compressed is.

There is no modification to decompression side,
since decompression is only single-threaded for now.

943cff9c37 fixed zstdmt cli freeze issue with large nb of threads 
fileio.c was continually pushing more content without giving a chance to flush compressed one.
It would block the job queue when input data was accumulated too fast (requiring to define many threads).
Fixed : fileio flushes whatever it can after each input attempt.

512cbe8c10 zstdmt cli and API allow selection of section sizes 
By default, section sizes are 4x window size.
This new setting allow manual selection of section sizes.
The larger they are, the (slightly) better the compression ratio,
but also the higher the memory allocation cost,
and eventually the lesser the nb of possible threads,
since each section is compressed by a single thread.

It also introduces a prototype to set generic parameters,
ZSTDMT_setMTCtxParameter()

The idea is that it's possible to add enums
to extend the list of parameters that can be set this way.
This is more long-term oriented than a fixed-size struct.
Consider it as a test.
