Yann Collet 88ed0b630e api: LZ4F_getMaxNbWorkers() reports multi-threading support ; CLI thread cap follows liblz4, lz4 -V reports multithreading (checkpoint) ...

LZ4F_getMaxNbWorkers() (static linking only, experimental like nbWorkers) :
0 when liblz4 is built without LZ4F_MULTITHREAD, otherwise the cap of nbWorkers,
now 1024 on 64-bit systems and 128 on 32-bit ones (was 200).
lz4 : build macro LZ4_NBWORKERS_MAX removed ; worker threads of frame and legacy
formats are capped by LZ4F_getMaxNbWorkers(), 1 without liblz4 multi-threading
(restores a cap for the legacy format on POSIX). lz4 -V reports "multithread"
only when both lz4 and liblz4 support it ; -T# warning and -v note accordingly.
VS2022 _test.bat checks the version line, catching a CLI built without LZ4F_MULTITHREAD
(same output, so no other observable difference).
frameMT : validateMaxNbWorkers ; test builds use LZ4F_NBWORKERS_MAX=128.
