[elpa] externals/pq 04c91e8374 63/63: add pq.el and move pq.c -> pq-core.c

[ELPA Syncer]

branch: externals/pq
commit 04c91e8374bdfe7c2f973a0123c770910f1341bb
Author: Tom Gillespie <tgbugs@gmail.com>
Commit: Tom Gillespie <tgbugs@gmail.com>

    add pq.el and move pq.c -> pq-core.c
    
    The objective of this is to keep *elpa packaging systems happy by having
    an elisp file that matches the name of the package.
    
    Also updated the Makefile to use emacs to get the version and look for
    emacs-module.h in /usr/share/emacs/${emacs-version}/src/ and in
    /usr/include/emacs-${emacs-major-version}-*/.
