* generic/tclDTrace.d (new file): add DTrace provider for Tcl; allows
* generic/tclCompile.h: tracing of proc and command entry &
* generic/tclBasic.c: return, bytecode execution, object
* generic/tclExecute.c: allocation and more; with essentially
* generic/tclInt.h: zero cost when tracing is inactive;
* generic/tclObj.c: enable with --enable-dtrace configure
* generic/tclProc.c: arg (disabled by default, will only
* unix/Makefile.in: enable if DTrace is present).
* unix/configure.in: [Patch 1793984]
* macosx/Makefile: enable DTrace support.
* unix/configure: autoconf-2.13
