liblzma: Include cached memory in reported memusage in threaded decoder.
This affects lzma_memusage() and lzma_memlimit_set() when used with the threaded decompressor. Now all allocations are reported by lzma_memusage() (so it's not misleading) and lzma_memlimit_set() cannot lower the limit below that value. The alternative would have been to allow lowering the limit if doing so is possible by freeing the cached memory but since the primary use case of lzma_memlimit_set() is to increase memlimit after LZMA_MEMLIMIT_ERROR this simple approach was selected. The cached memory was always included when enforcing the memory usage limit while decoding. Thanks to Jia Tan.
