SERVER-13989: clean up quota api
SERVER-14418 Introduce unittest::assertGet, use in replication_executor_test.
SERVER-14370 Core functionality for setLastOptime and awaitReplication in ReplicationCoordinatorImpl
SERVER-14419 Improve error message when parseNumberFromString encounters a bad digit.
SERVER-14181: Test Hang Analyzer

Add a stub hang_analyzer.py for MCI to integrate with.
SERVER-4345 Add support processing fifo files in mongorestore

Example : `./mongorestore -d test -c foo_dupl <(mongodump -d test -c foo -out - 2>/dev/null | tail -n+2)`
Example (after pull #204) : `./mongorestore -d test -c foo_dupl <(mongodump -d test -c foo -out - 2>/dev/null)`

This closes #205

SERVER-4345 mongorestore will read from stdin when filename is "-"
            check eof only on fifo files. restored original logic of checking bytes read against file length.
            mongorestore requires both --db and --collection when using stdin/fifo
SERVER-14419 Correctly parse the "masterHost" argument to Cloner::go into a ConnectionString, not a HostAndPort.

The argument represents a ConnectionString, but we parse it into a HostAndPort
when doing isSelf checks.  This was an error before that led checks to succeed
incorrectly, but fails with the new HostAndPort parsing code from SERVER-14419.
SERVER-14419 Introduce unittest of HostAndPort; make ":123" unparseable due to lack of host component.
SERVER-14419 Implement HostAndPort::parse.
SERVER-14426 Add a StringData method to BSONElement
SERVER-14318 Use structs for replication command arguments
SERVER-14254 convert _v8_function from function pointer to boolean
SERVER-14254 (v8-3.25) convert _v8_function from function pointer to boolean
SERVER-14254 added jstest for _v8_function.toString()
