Message:

Introduce context_swap() and use it to simplify fibril implementation.

This wraps the use of context_save()/context_restore(), to provide a more
natural (and easier to understand) control flow. The patch also hides the
details of the underlying context, requiring the use of context_get_pc()
to acquire program counter. This might allow context_swap() to only store
one pointer in the context, storing the remaining information in its stack
frame. However, that is not done in this patch.
