[PATCH 0/4] support SWIG-generated Xapian binding

[Eric Wong <e@80x24.org>]

Xapian upstream is slowly migrating to a SWIG-generated
Perl binding and plans to drop the XS-based Search::Xapian
at some point:  https://trac.xapian.org/ticket/523

The SWIG-generated "Xapian" binding seems to work fine with
some minor tweaks to our own code, and we can support both
the old and new bindings.

OpenBSD (tested 6.5) only has the SWIG-generated binding,
FreeBSD packages both, and Debian only has Search::Xapian.

With this, OpenBSD users may now enjoy Xapian-based search.

PATCH 1/4 is is a huge cleanup for our test cases, making
PATCH 3/4 easier-to-implement.  I'm kinda annoyed at PATCH 2/4
because I'm no fan of operator overloading, but oh well,
we used "!=" instead of "->nequal" in those loop, anyways :x

Eric Wong (4):
  testcommon: add require_mods method and use it
  searchidx: call "++" on PostingIterator instead of "->inc"
  search: support SWIG-generated Xapian.pm
  t/search.t: update permissions check for OpenBSD
