Add StringData::rfind(char) const method.
SERVER-8952 Add argument type checking to Timestamp constructor in Javascript shell
Get rid of "args" global in V8
Attach V8Scope to v8::Isolate's Data

Frees the accessor data up for other uses
Cache conversion of string literals to V8 Strings
Add V8String class to avoid copying v8::Strings into std::strings

Still need to copy once into v8::Utf8Value but this saves the second copy
Remove post-install dependency on murmurhash3 from client
SERVER-9605 Use correct string length in hexToBinData()

Do not use hard-coded length of 16 to process variable length hex string.
SERVER-9597: In JavaScript, only allow Mongo() to be called as a constructor
Make "bare assert" check more selective

Do not trigger "bare assert" error when " assert(" appears in a
quoted string, as it does in src/mongo/shell/mongo.cpp for example
(as generated by the Visual Studio build).
SERVER-9878 Add type checks to V8 C++ bindings

The main focus of this ticket is tightening up input validation in
our V8 bindings. Doing this required normalizing the way we create
custom types in JS that have special C++-driven behavior. All special
types now use FunctionTemplates that are attached to the V8Scope object.
This allows us to test if an object is of the correct type before using
it.
