8930c6e551 Use ZSTD_CCtxParams_init() to Init CCtxParams, not memset() 
Even if the discrepancies are at the moment benign, it's probably better to
standardize on using the one true initializer, rather than trying (and failing)
to correctly duplicate its behavior.

resolving cparams. If not, fall back.

DDSS for Lazy: Implement a Dedicated Dictionary Chain Table

d6246d4a0f Print More During Fuzzer Test to Avoid CI Killing it Due to Timeout 
This is kind of hacky. And maybe this test doesn't need to be permanently as
exhaustive as it is now. But while we're actively developing the DDSS, we
should ensure it's compatible across many different modes.

06d240b8a7 Use All Available Space in the Hash Table to Extent Chain Table Reach 
Rather than restrict our temp chain table to 2 ** chainLog entries, this
commit uses all available space to reach further back to gather longer
chains to pack into the DDSS chain table.

9b9feb84f2 Lay Out Chain Table Chains Contiguously 
Rather than interleave all of the chain table entries, tying each entry's
position to the corresponding position in the input, this commit changes the
layout so that all the entries in a single chain are laid out next to each
other. The last entry in the hash table's bucket for this hash is now a packed
pointer of position + length of this chain.

This cannot be merged as written, since it allocates temporary memory inside
ZSTD_dedicatedDictSearch_lazy_loadDictionary().

07793547e6 Fix Bug: Only Use DDSS Insertion on CDict MatchStates 
Previously, if DDSS was enabled on a CCtx and a dictionary was inserted into
the CCtx, the CCtx MatchState would be filled as a DDSS struct, causing
segfaults etc. This changes the check to use whether the MatchState is marked
as using the DDSS (which is only ever set for CDict MatchStates), rather than
looking at the CCtxParams.
