Try hard to find the symbolic (declared in .proto file) name
for the given value.
Will use enums in fdinfo, thus prepare.

This one walks the 'plain' image file, i.e. the one with straignt <magi>[<size><entry>]*
format, and prints each message. Saves lots of lines of code.

This function can be used for any protobuf message which contains required,
repeated and even nested messages fields.
The functions doesn't support yet:
1) Optional fields (skipped)
2) Fields types: PROTOBUF_C_TYPE_FLOAT, PROTOBUF_C_TYPE_DOUBLE,
PROTOBUF_C_TYPE_BOOL, PROTOBUF_C_TYPE_ENUM, PROTOBUF_C_TYPE_BYTES.
These are show as unknown objects.
IOW, it supports only existent proto files.

To not bloat util.h or image.h the protobuf.h introduced to handle all PB needs.
We represent our PB objects as pairs of records
| 4 bytes for object packed size
+---
| X bytes -- object itself
v3:
- Use plain read/write calls
- Use local buffers for small objects
v4:
- Add pb_pksize helper to calculate object
size with header
