* add constants for dlopen flags, which are needed for dlopen's flag passing. * introduce an optional parameter for process.dlopen(), allowing to pass dlopen flags (using values from os.constants.dlopen). If no flags are passed, the default behavior is to load the library with RTLD_LAZY (perform lazy binding) and RTLD_LOCAL (symbols are available only locally).

Setting the environment variable
NODE_RTLD_GLOBALtotruesetRTLD_GLOBALflag when loading module.This pull request is motivated by the fact that
dlopendoes not have the same behavior on MacOS X and Linux (cf.dlopenman page) :I was not sure what name would be the best to use for this purpose, so this is a first suggestion, but I'd be happy to change them. Also, I've implemented that as an opt-in mode, with as few changes as I could, but I'd be also happy to extend the idea and provide more flexibility.
Note : I'm no Windows expert, so I was not sure how what to do for this implementation.
Many thanks in advance for considering this patch.
