Andrew Mahone 23d9812273 loader-initialized global plugin API: 
struct plugin_api *rb is declared in PLUGIN_HEADER, and pointed to by
__header.api

the loader uses this pointer to initialize rb before calling entry_point

entry_point is no longer passed a pointer to the plugin API

all plugins, and pluginlib functions, are modified to refer to the
global rb

pluginlib functions which only served to copy the API pointer are
removed
