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.

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.

Summary:
A couple of notes from the diff:
- The namespace block I added at the top of table_properties_collector.cc was in reaction to an issue i was having with PutVarint64 and reusing the "val" string. I'm not sure this is the cleanest way of doing this, but abstracting this out at least results in the correct behavior.
- I chose "rocksdb.merge.operands" as the property name. I am open to suggestions for better names.
- The change to sst_dump_tool.cc seems a bit inelegant to me. Is there a better way to do the if-else block?
Test Plan:
I added a test case in table_properties_collector_test.cc. It adds two merge operands and checks to make sure that both of them are reflected by GetMergeOperands. It also checks to make sure the wasPropertyPresent bool is properly set in the method.
Running both of these tests should pass:
