MongoDB Legacy C++ Driver 1.0.0-rc4

Bug

• [CXX-449] - Aggregate cursor with no results against MongoDB 2.2/2.4 responds true to more()
• [CXX-451] - Driver doesn't compile on systems without strnlen
• [CXX-452] - Cannot build as shared library on Solaris

Improvement

• [CXX-229] - Ensure internally iterated cursor pointers are not null
• [CXX-286] - Support additional custom compiler and linker options when invoking scons (e.g. rpath)
• [CXX-355] - Remove thread name support from driver
• [CXX-389] - Add support for auth to CopyDb helper
• [CXX-465] - Remove legacy BSON typedefs
• [CXX-284] - Build fall back to environment boost libraries when providing custom version
