* adding long support for patch-from

* adding refPrefix to dictionary_decompress

* adding refPrefix to dictionary_loader

* conversion nit

* triggering log mode on chainLog < fileLog and removing old threshold

* adding refPrefix to dictionary_round_trip

* adding docs

* adding enableldm + forceWindow test for dict

* separate patch-from logic into FIO_adjustParamsForPatchFromMode

* moving memLimit adjustment to outside ifdefs (need for decomp)

* removing refPrefix gate on dictionary_round_trip

* rebase on top of dev refPrefix change

* making sure refPrefx + ldm is < 1% of srcSize

* combining notes for patch-from

* moving memlimit logic inside fileio.c

* adding display for optimal parser and long mode trigger

* conversion nit

* fuzzer found heap-overflow fix

* another conversion nit

* moving FIO_adjustMemLimitForPatchFromMode outside ifndef

* making params immutable

* moving memLimit update before createDictBuffer call

* making maxSrcSize unsigned long long

* making dictSize and maxSrcSize params unsigned long long

* error on files larger than 4gb

* extend refPrefix test to include round trip

* conversion to size_t

* making sure ldm is at least 10x better

* removing break

* including zstd_compress_internal and removing redundant macros

* exposing ZSTD_cycleLog()

* using cycleLog instead of chainLog

* add some more docs about user optimizations

* formatting
