From Revision 719

Rev	Summary	Authors	Date
502	Misc cleanups. Misc cleanups. - Use NULL for pointers rather than None. - bool-ify a few boolean funcs, and void-ify a few whose returns are meaningless or never checked anyway. Mostly in parsing code. - Few trivial const-ifications. - Fixup transposed lteters in a few func names. - Few other minor consistency fixes nearby.	Matthew Fuller	8 years ago
497	Convert several vars that are used as enums into actual enum... Convert several vars that are used as enums into actual enums. Notably, this affects config vars in struct Screen (and subsidiary vars in other structs) relating to various Alignement[sic] and Justification, which used different partly-overlapping sets of J_* #defines, which were also used in other parts of the code for various other unrelated things. Add individual types for all of those uses so they're properly distinguishable, and GC the #define's. Includes a few other similar type changes, and some incidentals found along the way.

Probably more uncaught cases of everything still lurking to be found. - Consistently use C99 bool type and true/false values for boolean vars, struct elements, function arguments, return values, and constants. This replaces inconsistent uses of int's and shorts, with 1/0 and TRUE/FALSE #define values, and a number of uses of X11 Bool type and True/False values (in all sorts of mis-combinations). Bool and True/False are still retained for places where they're used with Xlib, as that's the right type there. - Some minor renaming of vars and struct elements in that process. - Various header file cleanups. Include where used, but don't make them broader than necessary (e.g., #including in a .h because you need it in the .c, in most cases). When something's in ctwm.h, we don't need it elsewhere. GC unused includes, macros, and vars. extern specifier isn't needed or useful on function prototypes. Guard everything with the idempotency guards. - Various malloc() and friends cleanups. Don't even pretend to support systems where we have to prototype them ourselves. Don't cast malloc() returns and free() args. Use calloc() where appropriate. - Misc pre-c89 code cleanups. NULL is a pointer value, 0 (or casts of 0) aren't. Signal handlers return void. - Other minor changes found in the process.	Matthew Fuller	9 years ago
492	Cleanup various memory allocation stuff. Cleanup various memory allocation stuff. - Don't cast malloc() return, ANSI has some and gone. Ditto for free() arg. - Use calloc() in preference to malloc(num*size). Also in place of malloc();zero() in its various spellings. - Stop #include'ing <stdlib.h> in ctwm.h, and especially stop pretending to handle cases where we have to manually prototype malloc() and friends. Pull it into the files where we need it. - Use asprintf() in place of manual figuring;malloc();sprintf() constructions, and use strdup() in place of malloc();strcpy() constructs. - Few other minor nearby cleanups. Should be no functional change.	Matthew Fuller	9 years ago

This wound up being about 45% of util.c. The optional JPEG/XPM bits, as well as the individual image formats and usages, get split into their own files. This makes it easier to find the bits related to a specific part of the image process, as well as not have to flip through them all to find other util.c-bits. First step in "break up our gigantic fuzzily-themed source files".	Matthew Fuller	9 years ago
