Alexander Barton : Update configure.ng for autoconf 2.67 - ngIRCd GIT Updates

2 Jan 2014

Module: ngircd.git
Branch: master
Commit: bc098794ee45b5d5a2b9bb1a9c4f5be4136a2209
URL:    http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=bc098...

Update configure.ng for autoconf 2.67
We already require GNU autoconf 2.67 for generating our build system (at
least this is what the INSTALL document states), so update the build system
accordingly and implement all changes that autoupdate(1) suggests:
- Update AC_PREREQ and AC_INIT
 - Use AC_LINK_IFELSE, AC_RUN_IFELSE, and AC_COMPILE_IFELSE
 - Remove AC_TYPE_SIGNAL (we don't use RETSIGTYPE)
