When a stream is obviously a file or memory stream (both of which
implement the GSeekable interface), use g_seekable_seek() instead of
camel_stream_reset().
This is helping me discover if it's safe to remove camel_stream_reset().
We want to eventually move to GIO streams, which have no reset method.
- Require all EPlugin and EPluginHook subtypes be registered before
loading plugins. This drastically simplifies the EPlugin/EPluginHook
negotiation.
- Turn most EPluginHook subtypes into GTypeModules and register their
types from an e_module_load() function (does not include shell hooks).
- Convert EPluginLib and the Mono and Python bindings to GTypeModules
and register their types from an e_module_load() function, and kill
EPluginTypeHook.
