Fixed a bunch of bugs related to callback fields.

Most importantly, callback fields in submessages were being overwritten with garbage, causing segfaults.

Additionally, converted PB_LTYPE_FIXED to PB_LTYPE_FIXED32 and PB_LTYPE_FIXED64. This makes the interface
a bit easier to use, and in addition runs faster.
