(The CID numbers are the "Coverity IDs" used to identify the various bugs)

- Don't free binbuf within glist_readfrombinbuf (CID:74871)
- it must be deleted by the caller
- Initialize sockaddr_in (CID:74861,74862,74863,74866)
- Initialize indelay/outdelay (CID:74864,74865)
- Initialize device-arrays (CID:74853,74854,74855,74856)
- Closing unneeded sockets (CID:74827)
- Initialize sockaddr_in (CID:74860}
- Close file-descriptor if the soundfile is unparsable (CID:74822,74823)
- Close file-handle in cleanup (CID:74816)
- Call va_end() when handling variadic args (CID:74872)
- Added missing break (CID:74800)
- Prevent NULL-dereferences (CID:74792,74793)
- Size checks when copying into string buffers (CID:74844,74845,74846,74847,74849)
- Freeing no-more used storage (CID:74832)
- Fixed code block (CID:74806)
- Initialize sockaddr_in (CID:74860)
- Initialize array-values to 0 (CID:74867)
- Free allocated memory (CID:74813,74830)
- Removed allocation of unused memory
- Use pd_free() to free templates (CID:74814)
- template_free() does not free the entire structure (it misses the pd_new() part)
- initialize variable (CID:77865)
- Prevent NULL-pointer dererencing (CID:77864)
- Free heap-allocate binbuf after use (CID:74833)

oops... use binbuf_restore instead of binbuf_add to get dollargs to do the "right thing". Also fixed a debugging comment to keep it from printing garbage

*started cleaning up addbinbuf--it seems like comment object will need to be treated differently from others as commas, semis, and other reserved characters have unexpected behaviors.

*stretchable objects (like 0.45) with undo/redo capability, diagonal resize cursor, and minimum gop size.

merged patches from https://sourceforge.net/tracker/?func=detail&atid=478072&aid=2947822&group_id=55736

binbuf_print now hides all arguments following the %hidden% atom when reporting errors on the console

Removed show-stopping bug in addsemi that was added while debugging segfaults with canvas undo/redo.
