Summary:
I'm concerned about a random seg-fault that sometimes occurs when
running stringappend_test. I will investigate further. First, I am removing
stringappend_test from the regular release tests, and making some clean-ups
to the code.
Test Plan:
1. make stringappend_test
2. ./stringappend_test

Summary:
Implemented the StringAppendOperator class (subclass of MergeOperator).
Found in utilities/merge_operators/string_append/stringappend.{h,cc}
It is a rocksdb Merge Operator that supports string/list concatenation
with a configurable delimiter.
The tests are found in .../stringappend_test.cc. It implements a
map : key -> (list of strings), with core operations Append(list_key,val)
and Get(list_key).
Test Plan:
1. Navigate to your rocksdb repository
2. Execute: make stringappend_test (to compile)
3. Execute: ./stringappend_test (to run the tests)
4. Execute: make all check (to test the ENTIRE rocksdb codebase / regression)
