Dmitri Smirnov f4b72d7056 Provide a way to override windows memory allocator with jemalloc for ZSTD ... Summary: Windows does not have LD_PRELOAD mechanism to override all memory allocation functions and ZSTD makes use of C-tuntime calloc. During flushes and compactions default system allocator fragments and the system slows down considerably. For builds with jemalloc we employ an advanced ZSTD context creation API that re-directs memory allocation to jemalloc. To reduce the cost of context creation on each block we cache ZSTD context within the block based table builder while a new SST file is being built, this will help all platform builds including those w/o jemalloc. This avoids system allocator fragmentation and improves the performance. The change does not address random reads and currently on Windows reads with ZSTD regress as compared with SNAPPY compression.
