This reverts commit dc2da0edc5.
Add pb_close_string_substream() for copying back the state.
This makes adding error messages easier in the future, as also
them need to be propagated back from the substream.
This makes the field decoding functions more intuitive to use.
The old interface is still present if you specify NANOPB_INTERNALS.
Update issue 2
Status: FixedInGit
This makes it unnecessary to copy back the state, and also relaxes
the requirements on callbacks (bytes_left will always be valid).
It decreases code size by a few bytes, but may be just slightly slower.
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.
