- the actual perl script wasn't even included in the dist tarball

tests: ignore stderr for expect
expect redirects both stdout and stderr to its input. This causes
serious problems when libzebra prints log messages to stderr, which are
then asynchronously inserted in the middle of lines of stdout test
output. Ultimately this makes testbgpmpattr fail on FreeBSD.
(The stdio buffering seems to be slightly different on FreeBSD,
triggering the bug.)
Just ignore stderr for expect.

Introduce internal and IANA defintions for AFI/SAFI and mapping
functions and modify code to use these. This refactoring will
facilitate adding support for other AFI/SAFI whose IANA values
won't be suitable for internal data structure definitions (e.g.,
they are not contiguous).
The commit adds some fixes related to afi/safi testing with 'make check
