Implementation of TIP 118:

	* generic/tclFCmd.c (TclFileAttrsCmd): return the list of attributes
	that can be retrieved without error for a given file, instead of
	aborting the whole command when any error occurs.

	* unix/tclUnixFCmd.c: added support for new file attributes and for
	copying Mac OS X file attributes & resource fork during [file copy].

	* generic/tclInt.decls: added declarations of new external commands
	needed by new file attributes support in tclUnixFCmd.c.

	* macosx/tclMacOSXFCmd.c (new): Mac OS X specific implementation of
	new file attributes and of attribute & resource fork copying.

	* mac/tclMacFCmd.c: added implementation of -rsrclength attribute &
	fixes to other attributes for consistency with OSX implementation.

	* mac/tclMacResource.c: fixes to OSType handling.

	* doc/file.n: documentation of [file attributes] changes.

	* unix/configure.in: check for APIs needed by new file attributes.

	* unix/Makefile.in:
	* unix/tcl.m4: added new platform specifc tclMacOSXFCmd.c source.

	* unix/configure:
	* generic/tclStubInit.c:
	* generic/tclIntPlatDecls.h: regen.

	* tools/genStubs.tcl: fixes to completely broken code trying to
	prevent overlap of "aqua", "macosx", "x11" and "unix" stub entries.

	* tests/unixFCmd.test: added tests of -readonly attribute.

	* tests/macOSXFCmd.test (new): tests of macosx file attributes and
	of preservation of attributes & resource fork during [file copy].

	* tests/macFCmd.test: restore -readonly attribute of test dir, as
	otherwise its removal can fail on unices supporting -readonly.
