Plain copy-file no longer chmods an existing destination.

Remove arg STATPTR. All uses changed.
(Fcopy_file): Do not alter permissions of existing destinations,

PRESERVE-EXTENDED-ATTRIBUTES) is non-nil.
Avoid race when testing for existing destinations and for
when input and output files are the same.
If changing the group fails, adjust both default and
preserved permissions so that access is not granted to the
wrong group.
(Fset_default_file_modes, init_fileio): Update realmask.
(Fdefault_file_modes): Use realmask instead of calling umask.

(XCRUN): Don't require Darwin for xcrun. Move xcrun checking to

and automake clearer.
(CC): Don't use AC_PROG_CC twice; only the first use expands to the
shell code that is wanted, which breaks 'configure' on non-Darwin
platforms. Instead, fix CC by hand if it's not found.
