dict: merge static/non-static dict_set_* variations
Copy/pasting complete functions for setting one boolean is rather ugly, this can easily be solved with a helper function that gets the boolean as an extra parameter. Also removing dict_set_dynmstr() because there are no callers, and using GF_MALLOC() or GF_CALLOC() to allocate memory for strings is much more preferred. And, as Kaleb pointed out, prefixing functions with an underscore '_' is reserved for libc internals. Renaming the _dict_*() functions for that reason.
