math/abacus: Deprecate

The shared library is broken and no one stepped up in ~3 years to fix
it.

- Fix trailing whitespace in pkg-descrs, categories [g-n]*

Approved by:	portmgr blanket

Remove ${PORTSDIR}/ from dependencies, categories m, n, o, and p.

Convert LICENSE= "GPLxx # or later" to "GPLxx+"

Approved by:	portmgr blanket

Fix usage of ${PERL5}.

${PERL5} points to a specific version of perl, say, perl5.22.1, it is
fine to use it in a ports Makefile to do Perly things, but ports using
it must use ${PERL}, that points to /usr/local/bin/perl so that if the
minor version is updated, the shebang keep working.

While there, make some ports use shebangfix, regen a few patches, and
bump PORTREVISION where a shebang went from PERL5 to PERL.

  ABACUS is a software system written in C++ that provides a framework for the
  implementation of branch-and-bound algorithms using linear programming
  relaxations. Cutting planes or columns can be generated dynamically
  (branch-and-cut, branch-and-price, branch-and-cut-and-price).
