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.
