Infrastructure that allows protocol buffers to be used in Quagga. The
changes below comprise of:
- Build hooks
- Protobuf definitions for common types.
- Library routines for working with protobuf, including functions
that help translate between common quagga types and their protobuf
equivalents.
Changes:
* qpb/{Makefile.am,README.txt,qpb.h,.gitignore}
Add the qpb library, which provides shared code and definitions
for using protocol buffers in quagga code.
* qpb/qpb.proto
Protobuf definitions that can be shared by all of quagga.
* qpb/linear_allocator.h
An allocator that allocates memory by walking down towards the end
of a buffer. This is used to cheaply allocate/deallocate memory on
the stack for protobuf operations.
* qpb/qpb_allocator.[ch]
Thin layer that allows a linear allocator to be used with the
protobuf-c library.
* common.am
This is an automake fragment that is intended to be shared by
Makefile.am files in the tree. It currently includes definitions
related to protobuf.
* configure.ac
- Add logic to optionally build protobuf code.
By default, protobuf support is enabled if the protobuf C
compiler (protoc-c) is available, and the associated header
files/library can be found.
The user can choose to override this behavior via the new
--disable-protobuf/--enable-protobuf flags.
- Include the quagga protobuf library (qpb) in the build.
* .gitignore
Ignore source code generated by protobuf compiler.
* Makefile.am
Add 'qpb' to the list of subdirectories.

Edited: Paul Jakma <paul.jakma@hpe.com>: Change the sense of the
configure enable option to require explicit specifying, as
an experimental feature.
