This adds support for just showing the version string
without the full welcome message if the log level is
less than the default. That means that you pass -q once
and you will just see "1.4.5".
This makes it easier to parse in scripts.
* 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
