Pull erofs updates from Gao Xiang: "The LZ4 global buffer count is now configurable instead of the previous per-CPU buffers, which is useful for bare metals with hundreds of CPUs. A reserved buffer pool for LZ4 decompression can also be enabled to minimize the tail allocation latencies under the low memory scenarios with heavy memory pressure.
In addition, Zstandard algorithm is now supported as an alternative since it has been requested by users for a while.
There are some random cleanups as usual.
Summary:
- Make LZ4 global buffers configurable instead of per-CPU buffers
- Add a reserved buffer pool for LZ4 decompression for lower latencies
- Support Zstandard compression algorithm as an alternative
- Derive fsid from on-disk UUID for .statfs() if possible
- Minor cleanups"

erofs: Zstandard compression support
Add Zstandard compression as the 4th supported algorithm since it becomes more popular now and some end users have asked this for quite a while [1][2].
Each EROFS physical cluster contains only one valid standard Zstandard frame as described in [3] so that decompression can be performed on a per-pcluster basis independently.
Currently, it just leverages multi-call stream decompression APIs with internal sliding window buffers. One-shot or bufferless decompression could be implemented later for even better performance if needed.

erofs: rename per-CPU buffers to global buffer pool and make it configurable
It will cost more time if compressed buffers are allocated on demand for low-latency algorithms (like lz4) so EROFS uses per-CPU buffers to keep compressed data if in-place decompression is unfulfilled. While it is kind of wasteful of memory for a device with hundreds of CPUs, and only a small number of CPUs concurrently decompress most of the time.
This patch renames it as 'global buffer pool' and makes it configurable. This allows two or more CPUs to share a common buffer to reduce memory occupation.

erofs: DEFLATE compression support
Add DEFLATE compression as the 3rd supported algorithm.
DEFLATE is a popular generic-purpose compression algorithm for quite long time (many advanced formats like gzip, zlib, zip, png are all based on that) as Apple documentation written "If you require interoperability with non-Apple devices, use COMPRESSION_ZLIB. [1]".
Due to its popularity, there are several hardware on-market DEFLATE accelerators, such as (s390) DFLTCC, (Intel) IAA/QAT, (HiSilicon) ZIP accelerator, etc. In addition, there are also several high-performence IP cores and even open-source FPGA approches available for DEFLATE. Therefore, it's useful to support DEFLATE compression in order to find a way to utilize these accelerators for asynchronous I/Os and get benefits from these later.
Besides, it's a good choice to trade off between compression ratios and performance compared to LZ4 and LZMA. The DEFLATE core format is simple as well as easy to understand, therefore the code size of its decompressor is small even for the bootloader use cases. The runtime memory consumption is quite limited too (e.g. 32K + ~7K for each zlib stream). As usual, EROFS ourperforms similar approaches too.
Alternatively, DEFLATE could still be used for some specific files since EROFS supports multiple compression algorithms in one image.
