Implement use of %perl_bootstrap

The problem of bootstrapping perl-bioperl and perl-bioperl-run on a new
architecture or perl release is well known and documented in Bug #537138.

It will soon be time to rebuild the perl ecosystem in Rawhide for perl 5.16,
and it would be good to be able to do this "cleanly" as if bootstrapping a new
architecture. The perl-bioperl* packages are not the only ones with circular
build dependencies, and the Perl SIG has been applying a methodology of doing
an initial build with a macro %perl_bootstrap defined so that packages with
circular dependency issues can be built in a way that breaks the cycles, and
then, once the ecosystem has been bootstrapped, those packages using
%perl_bootstrap can be rebuilt again with it undefined so as to create the
packages as their maintainers intended.

To that end, it would be good if you could implement the use of %perl_bootstrap
in perl-bioperl, to replace the commented-out filtering scheme currently in
place. The attached patch does this. There are two versions of the filters, one
for rpm 4.9 or later (F-15 or later) and one for earlier releases. Rather than
using the "rpm 4.8" style for this as currently used in the comments, I've
used
perl-specific dependency filtering that would work all the way back to EPEL-5
if the necessary dependencies were there, though I tested it using F-14.

Testing results:

F-14:

$ rpmdiff --ignore T current-build/perl-bioperl-1.6.1-11.fc14.noarch.rpm
new-build/perl-bioperl-1.6.1-11.fc14.noarch.rpm 
removed     REQUIRES rpmlib(VersionedDependencies) <= 3.0.3-1
$ 

$ rpmdiff --ignore T current-build/perl-bioperl-1.6.1-11.fc14.noarch.rpm
new-build-boot/perl-bioperl-1.6.1-11.fc14.noarch.rpm 
removed     REQUIRES perl(Bio::Tools::Run::Alignment::Clustalw)  
removed     REQUIRES perl(Bio::Tools::Run::GenericParameters)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Molphy::ProtML)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::Neighbor)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::ProtDist)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::ProtPars)  
removed     REQUIRES perl(Bio::Tools::Run::RemoteBlast)  
removed     REQUIRES rpmlib(VersionedDependencies) <= 3.0.3-1
$ 


Rawhide:

$ rpmdiff --ignore T current-build/perl-bioperl-1.6.1-11.fc18.noarch.rpm
new-build/perl-bioperl-1.6.1-11.fc18.noarch.rpm 
$ 

$ rpmdiff --ignore T current-build/perl-bioperl-1.6.1-11.fc18.noarch.rpm
new-build-boot/perl-bioperl-1.6.1-11.fc18.noarch.rpm 
removed     REQUIRES perl(Bio::Tools::Run::Alignment::Clustalw)  
removed     REQUIRES perl(Bio::Tools::Run::GenericParameters)  
removed     REQUIRES perl(Bio::Tools::Run::ParametersI)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Molphy::ProtML)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::Neighbor)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::ProtDist)  
removed     REQUIRES perl(Bio::Tools::Run::Phylo::Phylip::ProtPars)  
removed     REQUIRES perl(Bio::Tools::Run::RemoteBlast)  
removed     REQUIRES perl(Bio::Tools::Run::StandAloneBlast)  
removed     REQUIRES perl(Bio::Tools::Run::WrapperBase)  
$ 


Note that the older rpm in F-14 did not pick up as many perl dependencies as
Rawhide's rpm, hence fewer were filtered for the bootstrap build.

The disappearance of "REQUIRES rpmlib(VersionedDependencies) <= 3.0.3-1" in
the
F-14 builds is due to the change from "rpm 4.8" style filtering to the
perl-specific filtering.
