Revert "Add pb_decode_noinit and use it from pb_dec_submessage."

Browse Source 
The patch breaks default values inside submessage arrays (I think).
Have to add test cases and check back.

For optional fields, this function applies the default value and sets *has_<field>* to false if the field is not present.
pb_decode_noinit
----------------
Same as `pb_decode`_, except does not apply the default values to fields. ::
bool pb_decode_noinit(pb_istream_t *stream, const pb_field_t fields[], void *dest_struct);
(parameters are the same as for `pb_decode`_.)
The destination structure should be filled with zeros before calling this function. Doing a *memset* manually can be slightly faster than using `pb_decode`_ if you don't need any default values.
pb_skip_varint
--------------
Skip a varint_ encoded integer without decoding it. ::
