(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)

port c6771297b6f03887034c5f121d3dbf701623ab87 from Pd-l2ork: the big Vanilla forward port won't compile without this commit

use <dialog> modal instead of javascript prompt. Also, port some changes from Vanilla to allow closing window immediately after saving

do a proper loadbang for canvas fields (needs more testing)

*fixed consistency check failed: glist_findrtext when enabling gop and dragging its size around with other text objects on the canvas
*refined checking of gop size due to its text not being hidden, including after saving it to file (from Untitled to something longer, for instance)

*added ability to do shift+home and shift+end to select text inside objects
*fixed manual resizing of subpatches which did not work in the current implementation.

*added getscroll after redrawing gop and scalars that have been changed via properties dialog in case their xy positions changed

*m_pd.c debugging info
*improved dealing with scalar properties editor (making it persistent and alleviating errors of things being multiply defined)

keep [drawsymbol] and [drawnumber] from flipping with negative gop scaling
default to black fill and no stroke, per svg spec
merged transform gui updates with other attributes
fixed tags so that array elements display properly
