* generic/tkFont.c: implementation of ATSUI text rendering

	* generic/tkInt.h:              in TkAqua provided by Benjamin
	* generic/tkTextDisp.c:         Riefenstahl. [Patch 638966]
	* library/demos/unicodeout.tcl:
	* macosx/tkMacOSXFont.h (new file):
	* macosx/tkMacOSXFont.c:
	* tests/font.test:
	* unix/tkUnixFont.c:
	* win/tkWinFont.c:

	* generic/tkFont.c:             moved MODULE_SCOPE declarations of
	* generic/tkFont.h:             font helper procs into header files.
	* macosx/tkMacOSXButton.c:
	* macosx/tkMacOSXFont.h:
	* macosx/tkMacOSXMenubutton.c:

	* macosx/Wish.xcode/project.pbxproj:     add new tkMacOSXFont.h file,
	* macosx/Wish.xcodeproj/project.pbxproj: turn off dead code stripping
	as it interferes with -sectcreate (rdar://4486223).

	* macosx/Wish.xcode/default.pbxuser:     add TCLLIBPATH=/Library/Tcl
	* macosx/Wish.xcodeproj/default.pbxuser: env var setting to tktest.

	* unix/configure.in: fix detection of symbols build when enabling
	TkAqua debug code; filter nm output of libtclstub better to avoid
	error on intel macs [Bug 1415789].
	* unix/configure: autoconf-2.59
