Fix rpl.rpl_4threads_deadlock test broken by D5005670
Summary:
In D5005670 in fill_fields_processlist() function we introduced a point
where we were trying to take the LOCK_thd_data before the
synchronization point used by test
processlist_after_LOCK_thd_count_before_LOCK_thd_data. This was
happening in get_attached_srv_session() function called. Replaced this
with get_attached_srv_session_safe() and moved it after lock is aquired.

use CMAKE_CXX_STANDARD to set C++11 flags with CMake 3.1+ (apples flags are somehow different from standard clang)
port htonbe16/32/64 macros for rocksdb
use reinterpret_cast<size_t> to cast macOS's pthread_t (pointer type) to size_t , for rocksdb
Either we are building from a source package, in which case all sources
should be present, or we are building from a repository. The repository
needs to fetch the rocksdb submodule before building rocksdb.

Improve add_index_alter_cardinality test
Summary:
Split add_index_inplace_cardinality test out and add a debug_sync point
to it so that the flush of the memtable occurs while the alter is
running.

This change add WITH_ROCKSDB_{LZ4,BZIP2,ZSTD,snappy} CMake variables
that can be set to ON/OFF/AUTO.
If variable has default value AUTO, rocksdb links with corresponding
compression library. OFF disables compiling/linking with specific compression
library, ON forces compiling with it (cmake would throw error if library
is not available)
Support for ZLIB is added unconditionally, as it is always there.
- port Regex_list_handler from facebook/mysql-5.6/sql/handler.cc
put it into a separate file in storage/rocksdb directory
- Adjust the build process so that the main library is build with
Regex_list_handler (which has dependencies on the server),
while RocksDB tools are built without it.
- Un-comment @@rdb_collation_exceptions handling in ha_rocksdb.cc
- Also adjust rocksdb_set_collation_exception_list() to free the
old variable value and alloc the new one.
- RocksDB uses RTTI (e.g. it uses dynamic_cast)
- mysql-5.6 has RTTI enabled for the whole server, so there's no
conflict.
- MariaDB doesn't have RTTI enabled
So the solution is to enable RTTI for
- RocksDB files
- Parts of MyRocks that interface with RocksDB features that require RTTI.
(If one just enables RTTI for all of MyRocks, they will get a
"undefined reference to `typeinfo for handler'" link error)
