plugins: move common functions and variables from OS-specific headers to mumble_plugin_main.h

This is in preparation for the new Source Engine plugin which will add a few common functions.

This commit also improves the functions arguments so that they are passed by reference and marked as const (when possible).

A new data type called procid_t is created, intended to be a replacement for pid_t (Linux) and DWORD (Windows).
