*updated most of the audio API to the latest version (with the exception of ALSA and JACK which are partial until our improvements can be merged and/or new implementation of JACK thoroughly tested to ensure we like its default behavior)

*removed text editor since now pd-l2ork's facility for editing text inside object boxes is adequate enough not to require a full-fledged editor

Patch put on tracker for Pd-extended, but I thought I'd go ahead and commit here, too

This change allows gobjs to be pointed to by gpointers.  This makes it
possible to improve the interface for the *info objects, as they can pass
around lists of gpointers to refer to objects/canvases.  This is better than
using index numbers and canvas levels, which is cumbersome and in some cases
much slower (since a walk through the glist is required each time to find
the referrent for an index).

* properly escaped "boxtext" output
* output expanded args for canvasinfo "args"

*added new files from the latest pure-data/externals/maxlib tree to git (missing files resultted in a failed build)

*fixed regression where cnv objects captured runtime clicks due to pd-l2ork's passing of the click to the topmost visible object, rather than the first clickable object in the stack. This also fixes problems with legacy patches that rely vanilla/extended's assignment of click to the lowest, and as is the case with s-env-help.pd in s-abstractions, invisible object, rather than the one apparent to the user.

*finally fixed the memory leak and improved how the newlines are created inside objects (needs further testing)

*fixed positioning of autopatched objects that were placed immediately below typed objects that have not been activated yet.

*fixed inconsistent display of array styles between pd-l2ork and vanilla. LATER consider cleaning this up by adjusting g_canvas.h instead of all these workarounds.

*backported vanilla patch http://sourceforge.net/p/pure-data/pure-data/ci/f535c339c99a74edb3920c2e630500df128b7d8f/

fixed bug with 8x8 click "hotspot" not working correctly on x-axis of garrays

*added sanity check for mknob (a subset of iemgui) to see if selected status would require object to be highlighted (if inside graph-on-parent, it should be silently selected but not visibly selected)
*fixed regression where selected variable in the old_g_all_guis.inc did not allow for a value larger than 1-bit, resulting in selected=2 being selected=0
