Note: reviewed in https://reviews.facebook.net/D65115
- DBIter maintains a range tombstone accumulator. We don't cleanup obsolete tombstones yet, so if the user seeks back and forth, the same tombstones would be added to the accumulator multiple times.
- DBImpl::NewInternalIterator() (used to make DBIter's underlying iterator) adds memtable/L0 range tombstones, L1+ range tombstones are added on-demand during NewSecondaryIterator() (see D62205)
- DBIter uses ShouldDelete() when advancing to check whether keys are covered by range tombstones

* 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.

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.

This is a proof of concept of a RocksDB blob log file. The actual value of the Put() is appended to a blob log using normal data block format, and the handle of the block is written as the value of the key in RocksDB.

getline on std::cin can be very inefficient when ldb is loading large values, with high CPU usage in libc _IO_(un)getc, this is because of the performance penalty that comes from synchronizing stdio and iostream buffers.
See the reproducers and tests in #1133 .
If an ifstream on /dev/stdin is used (when available) then using ldb to load large values can be much more efficient.
I thought for ldb load, that this approach is preferable to using <cstdio> or std::ios_base::sync_with_stdio(false).
I couldn't think of a use case where ldb load would need to support reading unbuffered input, an alternative approach would be to add support for passing --input_file=/dev/stdin.
I have a CLA in place, thanks.
The CI tests were failing at the time of https://github.com/facebook/rocksdb/pull/1156, so this change and PR will supersede it.

* DELETE_TEST_PATH: If true, then the test directory
will be deleted after the script ends.
Default: 0
2. Add more information in SUMMARY.csv
