153f4f0719 RocksDB: Allow Level-Style Compaction to Place Files in Different Paths
Summary:
Allow Level-style compaction to place files in different paths
This diff provides the code for task 4854591. We now support level-compaction
to place files in different paths by specifying  them in db_paths  along with
the minimum level for files to store in that path.

Test Plan: ManualLevelCompactionOutputPathId in db_test.cc

06eed650a0 Optimize default compile to compilation platform by default
Summary:
This diff changes compile to optimize for native platform by default. This will automatically turn on crc32 optimizations for modern processors, which greatly improves rocksdb's performance.

I also did some more changes to compilation documentation.

Test Plan:
compile with `make`, observe -march=native
compile with `PORTABLE=1 make`, observe no -march=native

Summary:
Priliminary diff to solicit comments.
Given DB path, dump all SST files (key/value and properties), WAL file and manifest
files. What command options do we need to support for this command? Maybe
output_hex for keys?

7ab1526c0e Add an assert and avoid std::sort(autovector) to investigate an ASAN issue
Summary:
ASAN build fails once for this error:

14:04:52 ==== Test DBTest.CompactFilesOnLevelCompaction
14:04:52 db_test: db/version_set.cc:1062: void rocksdb::VersionStorageInfo::AddFile(int, rocksdb::FileMetaData*): Assertion `level <= 0 || level_files->empty() || internal_comparator_->Compare( (*level_files)[level_files->size() - 1]->largest, f->smallest) < 0' failed.

Not abling figure out reason. We use std:vector for sorting for save and add one more assert to help figure out whether it is the sorting's problem.

ee95cae9a4 Modifed the LRU cache eviction code so that it doesn't evict blocks which have exteranl references
Summary:
Currently, blocks which have more than one reference (ie referenced by something other than cache itself) are evicted from cache. This doesn't make much sense:
- blocks are still in RAM, so the RAM usage reported by the cache is incorrect
- if the same block is needed by another iterator, it will be loaded and decompressed again

This diff changes the reference counting scheme a bit. Previously, if the cache contained the block, this was accounted for in its refcount. After this change, the refcount is only used to track external references. There is a boolean flag which indicates whether or not the block is contained in the cache.
This diff also changes how LRU list is used. Previously, both hashtable and the LRU list contained all blocks. After this change, the LRU list contains blocks with the refcount==0, ie those which can be evicted from the cache.

Note that this change still allows for cache to grow beyond its capacity. This happens when all blocks are pinned (ie refcount>0). This is consistent with the current behavior. The cache's insert function never fails. I spent lots of time trying to make table_reader and other places work with the insert which might failed. It turned out to be pretty hard. It might really destabilize some customers, so finally, I decided against doing this.

table_cache_remove_scan_count_limit option will be unneeded after this change, but I will remove it in the following diff, if this one gets approved

Test Plan: Ran tests, made sure they pass
