Remove internal copy of libpipeline.

* configure.ac: Remove --enable-socketpair-pipe and
  --with-external-pipeline options.  Remove INTERNAL_PIPELINE
  Automake conditional.  Check for libpipeline unconditionally.
* docs/INSTALL.quick: Mention the need to install libpipeline.
* gnulib: Remove strsignal and sys_select modules.
* lib/Makefile.am (libman_la_SOURCES): Never add pipeline.c or
  pipeline.h.
* lib/pipeline.c, lib/pipeline.h: Remove.
* m4/man-socketpair.m4: Remove.
* NEWS: Document this.  Bump to 2.6.0.
