ab01da5437 Support SST files with Global sequence numbers
Summary:
- Update SstFileWriter to include a property for a global sequence number in the SST file `rocksdb.external_sst_file.global_seqno`
- Update TableProperties to be aware of the offset of each property in the file
- Update BlockBasedTableReader and Block to be able to honor the sequence number in `rocksdb.external_sst_file.global_seqno` property and use it to overwrite all sequence number in the file

Something worth mentioning is that we don't update the seqno in the index block since and when doing a binary search, the reason for that is that it's guaranteed that SST files with global seqno will have only one user_key and each key will have seqno=0 encoded in it, This mean that this key is greater than any other key with seqno> 0. That mean that we can actually keep the current logic for these blocks

be1f1092c9 Expose transaction id, lock state information and transaction wait information
Summary:
This diff does 3 things:

Expose TransactionID so that we can identify transactions when we retrieve locking and lock wait information. This is exposed as `Transaction::GetID`.

Expose lock state information by locking all stripes in all column families and copying their contents to a data structure. This is exposed as `TransactionDB::GetLockStatusData`.

Adds support for tracking the transaction and the key being waited on, and exposes this as `Transaction::GetWaitingTxn`.

Test Plan: unit tests

87dfc1d23e Fix conflict between AddFile() and CompactRange()
Summary:
Fix the conflict bug between AddFile() and CompactRange() by
- Make sure that no AddFile calls are running when asking CompactionPicker to pick compaction for manual compaction
- If AddFile() run after we pick the compaction for the manual compaction it will be aware of it since we will add the manual compaction to running_compactions_ after picking it

This will solve these 2 scenarios
- If AddFile() is running, we will wait for it to finish before we pick a compaction for the manual compaction
- If we already picked a manual compaction and then AddFile() started ... we ensure that it never ingest a file in a level that will overlap with the manual compaction

* enable cmake to work on linux and osx also

* port part of build_detect_platform not covered by thirdparty.inc
  to cmake.
  - detect fallocate()
  - detect malloc_usable_size()
  - detect JeMalloc
  - detect snappy
* check for asan,tsan,ubsan
* create 'build_version.cc' in build directory.
* add `check` target to support 'make check'.
* add `tools` target to match its counterpart in Makefile.
* use `date` on non-win32 platforms.
* pass different cflags on non-win32 platforms
* detect pthead library using FindThread cmake module.
* enable CMP0042 to silence the cmake warning on osx
* reorder the linked libraries. because testutillib references gtest, to
  enable the linker to find the referenced symbols, we need to put gtest
  after testutillib.

* remove gtest from librocksdb linkage

testharness.cc is included in librocksdb sources, and it uses gtest. but
gtest is not supposed to be part of the public API of librocksdb. so, in
this change, the testharness.cc is moved out out librocksdb, and is
built as an object target, then linked with the tools and tests instead.

Summary:
Since AddFile unlock/lock the mutex inside LogAndApply() we need to ensure that during this period other compactions cannot run since such compactions are not aware of the file we are ingesting and could create a compaction that overlap wit this file

- Call `WaitForAddFile()` in 3 locations

-- When starting automatic Compaction
