Changed executable names to "file-foo". * plug-ins/Makefile.am: changed accordingly. * plug-ins/common/*: rename all file plug-ins to file-foo.c. Get rid of the names "poppler" and "postscript" and call them "file-pdf" and "file-ps" because the conflict with standard autofoo targets is gone. * plug-ins/common/plugin-defs.pl: changed accordingly. * plug-ins/common/mkgen.pl: make sure cflags variables are named "PLUG_IN_NAME_CFLAGS" and not "PLUG-IN-NAME_CFLAGS" * plug-ins/common/Makefile.am: regenerated. * configure.in: change folders and variable names to match above changes. svn path=/trunk/; revision=26494
