Wrapper structure for pseudo_bit_t structures.

This structure provides a wrapper around pseudo_bit_t structures. It has the correct size, and also encapsulates type information about the underlying pseudo_bit_t-based structure, which allows the BIT_FILL() etc. macros to work without requiring explicit type information.
