In the project I am working for, we are using the C++ mongodb driver in the main library and c-client in a "module library" that is loaded dynamically at runtime via dlopen.

Unfortunately, c-client and the C++ mongodb driver contain both the function md5_init. This fact caused a very strange behavior in our system. The md5_init function call in c-client was ignored and caused memory troubles.

Therefore, I propose to rename the md5_* functions that are declared in https://github.com/mongodb/mongo/blob/master/util/md5.h. As it seems to be already done in the C driver (see https://github.com/mongodb/mongo-c-driver/blob/master/src/md5.h).
