as well as
ROCKSDB_FBCODE_BUILD_WITH_481=1 make all -j32

Summary: This patch splits the posix storage backend into Env and
the actual *File implementations. The motivation is to allow other Envs
to use posix as a library. This enables a storage backend different from
posix to split its secondary storage between a normal file system
partition managed by posix, and it own media.
Test Plan: No new functionality is added to posix Env or the library,
thus the current tests should suffice.
Summary: Add ZSTD compression type. The same way as adding LZ4.
Test Plan: run all tests. Generate files in db_bench. Make sure reads succeed. But the SST files cannot be opened in older versions. Also some other adhoc tests.

Summary:
MyRocks is using jemalloc latest version, not 3.6.0.
Combining multiple versions (3.6.0 in RocksDB and latest in MyRocks)
broke some features -- for example, getting SIGSEGV when heap profiling
was enabled.
This diff switches to use jemalloc latest, if
env variable ROCKSDB_FBCODE_BUILD_WITH_481=1 was set.
My understanding is this env was used by MyRocks only so it would be
safe to change.
Test Plan: building MyRocks then verified jemalloc heap profiling worked

Summary:
Currently, when we insert something into block cache, we say that the block cache capacity decreased by the size of the block. However, size of the block might be less than the actual memory used by this object. For example, 4.5KB block will actually use 8KB of memory. So even if we configure block cache to 10GB, our actually memory usage of block cache will be 20GB!
This problem showed up a lot in testing and just recently also showed up in MongoRocks production where we were using 30GB more memory than expected.
This diff will fix the problem. Instead of counting the block size, we will count memory used by the block. That way, a block cache configured to be 10GB will actually use only 10GB of memory.
I'm using non-portable function and I couldn't find info on portability on Google. However, it seems to work on Linux, which will cover majority of our use-cases.
Test Plan:
1. fill up mongo instance with 80GB of data
2. restart mongo with block cache size configured to 10GB
3. do a table scan in mongo
4. memory usage before the diff: 12GB. memory usage after the diff: 10.5GB

Summary: I don't think we need to use whole-archive to include jemalloc. This change only affects our development builds -- it does not affect our open source builds (which don't support jemalloc) or our fbcode third-party2 builds (which use open-source build codepaths).
Test Plan:
make
verify that jemalloc is running by running `MALLOC_CONF="prof:true" ./cache_test` and observing that file was created
