052a95f77c fix : ZSTDMT_compress_advanced() correctly generates checksum 
when params.fParams.checksumFlag==1.
This use case used to be impossible when only ZSTD_compress() was available

32f546c763 zstreamtest : disabled multi-threading tests with --newapi --no-big-tests 
--no-big-tests is typically used in combination with qemu-user-static
qemu-user-static allocated 4 GB of RAM upfront.
On 2 GB VM, this can degenerate into a crash.
It's not a problem as long as memory is not used.
But with multi-threading enabled, memory fragmentation kicks in,
so the amoung of RAM effectively touched increases,
and can pass beyond the 2 GB limit of the VM.

In single-threaded mode, there is no such issue :
memory requirement is smaller, and remains well-located,
so very little fragmentation is expected.

This modification should make `qemu-arm-static zstreamtests --newapi --no-big-tests`
work fine on Travis CI.

8c910d2097 updated ZSTDMT streaming API 
ZSTDMT streaming API is now similar
and has same capabilites as single-thread streaming API.
It makes it easier to blend them together.

25989e361c updated ZSTD_estimate?DictSize() to pass parameter byReference 
resulting ?Dict object is smaller when created byReference.
Seems better than a documentation note.

a5ffe3d370 pushed enum values for strategy by one (ZSTD_fast==1) 
this makes it possible to use `0` to mean:
"do not change strategy"

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.

2c5514c759 fixed ZSTDMT_initCStream_advanced()

to enforce correct frame parameters

0bb381dad8 added test for ZSTD_initCStream_advanced() 
when params.fParams.contentSizeFlags = 1
and pledgedSrcSize = 0
then srcSize should be considered 0 (empty), and not "unknown"
