decode more data before triggering error

fbd5ab7027 minor fix : no longer use fake srcSize during resource creation 
srcSize is read and provided at each file, not at resource creation.
This used to be useful with older API, because it could not re-adapt parameters between sessions.

At some point, it will be better to remove the old code, and only keep the new_api.
It works fine by now.

db1668a43b fix : srcSize written in frame header when multiple files compressed 
This information used to be disabled when nbFiles>1.
It was badly initialized later in the code, resulting in an error.

1416bc0f07 erase existence of a buffer when it's sent out of the pool 
In some complex scenario,
the buffer would be freed because it's too large,
another buffer would be allocated, but fail,
trigger an error,
and the general buffer pool would then be freed,
where the definition of the already freed buffer would be found
(beyond total index, but still), and freed again, resulting in double-free error.

8afcc80e07 decode more data before triggering error 
fixes #874 :
when a frame is not properly terminated by a "last block" signal,
zstd -d used to detect it immediately and error out.
This version will decode and flush the last block, and only then issue an error.

e963800e27 zstdmt : fixed : buffer dst0 wasn't properly set to null after usage 
now it's possible to unconditionnally invoke ZSTD_releaseAllJobRessources()
wether previous compression was completed correctly or not.

9b5b47ac93 ensure adjustCParams adjust hLog and cLog even without srcSize 
It would previously exit when srcSize is unknown.
But in the case of custom parameters,
hLog and cLog can still be too large in comparison with windowLog.

Reduces maximum memory allocated during zstreamtest --newapi

ea1f50bf73 removed ZSTD_decompressBegin() from ZSTD_initDCtx_internal() 
It does not feel "right" from a dependency perspective.
ZSTD_initDCtx_internal() is triggered once, on DCtx creation,
while ZSTD_decompressBegin() is invoked at the beginning of each new frame,
and is also a user-facing prototype.

Downside : a DCtx must be init before first usage !
This was always the intention by the way, and is documented as such.
This stage is automatically done within ZSTD_decompress() and variants,
and also within ZSTD_decompressStream().
Only ZSTD_decompressContinue() is impacted,
it must be preceded by a ZSTD_decompressBegin(), as detailed in doc.

A test has been fixed, to no longer rely on undocumented assumption that ZSTD_decompressBegin() is invoked during init.

ca306c1c84 fixed a bug in zstreamtest 
decoder output buffer would receive a wrong size.

In previous version, ZSTD_decompressStream() would blindly trust the caller that pos <= size.
In this version, this condition is actively checked,
and the function returns an error code if this condition is not respected.

This check could also be done with an assert(),
but since this is a user-facing interface, it seems better to keep this check at runtime.
