wrapper C files in pluginlib renamed to the same name as the core files they
wrap
pluginlib-only init functions for resize and bmp moved into the wrapper files,
and declared in the associated header files
API() macro removed entirely, in favor of a core-only header file that
redefines core function names to use a plugin_api pointer
some unnecessary uses of PLUGIN in apps/recorder/bmp.c removed
