Summary:
We haven't been actively mantaining RocksDB LITE recently and the size must have been gone up significantly. We are removing the support.
Most of changes were done through following comments:
unifdef -m -UROCKSDB_LITE `git grep -l ROCKSDB_LITE | egrep '[.](cc|h)'`
by Peter Dillinger. Others changes were manually applied to build scripts, CircleCI manifests, ROCKSDB_LITE is used in an expression and file db_stress_test_base.cc.

Summary:
When dynamically linking two binaries together, different builds of RocksDB from two sources might cause errors. To provide a tool for user to solve the problem, the RocksDB namespace is changed to a flag which can be overridden in build time.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6433
Test Plan: Build release, all and jtest. Try to build with ROCKSDB_NAMESPACE with another flag.

Summary:
Previously, if the jemalloc was built with nonempty string for
`--with-jemalloc-prefix`, then `HasJemalloc()` would return false on
Linux, so jemalloc would not be used at runtime. On Mac, it would cause
a linker failure due to no definitions found for the weak functions
declared in "port/jemalloc_helper.h". This should be a rare problem
because (1) on Linux the default `--with-jemalloc-prefix` value is the
empty string, and (2) Homebrew's build explicitly sets
`--with-jemalloc-prefix` to the empty string.
However, there are cases where `--with-jemalloc-prefix` is nonempty.
For example, when building jemalloc from source on Mac, the default
setting is `--with-jemalloc-prefix=je_`. Such jemalloc builds should be
usable by RocksDB.
The fix is simple. Defining `JEMALLOC_MANGLE` before including
"jemalloc.h" causes it to define unprefixed symbols that are aliases for
each of the prefixed symbols. Thanks to benesch for figuring this out
and explaining it to me.
Fixes https://github.com/facebook/rocksdb/issues/1462.

Test Plan:
build jemalloc with prefixed symbols:
```
$ ./configure --with-jemalloc-prefix=lol
$ make
```
compile rocksdb against it:
```
$ WITH_JEMALLOC_FLAG=1 JEMALLOC=1 EXTRA_LDFLAGS="-L/home/andrew/jemalloc/lib/" EXTRA_CXXFLAGS="-I/home/andrew/jemalloc/include/" make -j12 ./db_bench
```
run db_bench and verify jemalloc actually used:
```
$ ./db_bench -benchmarks=fillrandom -statistics=true -dump_malloc_stats=true -stats_dump_period_sec=1
$ grep jemalloc /tmp/rocksdbtest-1000/dbbench/LOG

Summary:
Declare Jemalloc non-standard APIs as weak symbols, so that if Jemalloc is linked with the binary, these symbols will be replaced by Jemalloc's, otherwise they will be nullptr. This is similar to how folly detect jemalloc, but we assume the main program use jemalloc as long as jemalloc is linked: https://github.com/facebook/folly/blob/master/folly/memory/Malloc.h#L147

Summary:
The "je_" prefix of jemalloc APIs presents only when the macro `JEMALLOC_NO_RENAME` from jemalloc.h presents.
With the patch I'm also adding -DROCKSDB_JEMALLOC flag in buck TARGETS.

Summary:
This diff handles cases where compaction causes an ENOSPC error.
This does not handle corner cases where another background job is started while compaction is running, and the other background job triggers ENOSPC, although we do allow the user to provision for these background jobs with SstFileManager::SetCompactionBufferSize.
It also does not handle the case where compaction has finished and some other background job independently triggers ENOSPC.
Usage: Functionality is inside SstFileManager. In particular, users should set SstFileManager::SetMaxAllowedSpaceUsage, which is the reference highwatermark for determining whether to cancel compactions.

Summary:
This fixes a compilation failure on Linux when the system libc is not
glibc. jemalloc's configure script incorrectly assumes that glibc is
always used on Linux systems, producing glibc-style signatures; when
the system libc is e.g. musl, the following error is observed:

This works around the issue by rearranging the sources such that
jemalloc's headers are never in the same scope as the system's malloc
header. The jemalloc issue has been reported as well, see:
