* Makefile.am: listed tools first in SUBDIRS, so xgettext can grab the autogenned files * acconfig.h: removed unused HAVE_XSHM_H * tools/pdbgen/app.pl: added proc invoke method, nicer header formatting * tools/pdbgen/pdb/layer.pdb: use layer_mask type for return value for layer_create_mask * tools/pdbgen/pdb/misc.pdb: added quit proc * tools/pdbgen/pdb/tools.pdb: added ink proc, but not added to @procs since it's incomplete * tools/pdbgen/pdb/fileops.pdb: new file * app/Makefile.am: added fileops_cmds.c * app/app_procs.c * app/fileops.c * app/ink.c: removed PDB procs (the one in ink.c was incomplete) * app/fileops.h: exported load_procs, save_procs, and file_proc_find() * app/plug_in.h: exported enum, #include <sys/types.h> * app/brushes_cmds.c * app/fileops_cmds.c * app/layer_cmds.c * app/misc_cmds.c * app/parasite_cmds.c * app/patterns_cmds.c * app/procedural_db_cmds.c * app/text_tool_cmds.c * app/internal_procs.c: pdbgen updates * app/paint_funcs.c: the glibc 2.1 docs say using SVID threadsafe random functions are preferable to rand_r, so use them instead of a mutex -Yosh
