Prevent unintended file desriptor leak in grantpt.
The pt_chown program is completely transparently called. It might
not be able to live with the various file descriptors the program
has open at the time of the call (e.g., under SELinux). Close all
but the needed descriptor and connect stdin, stdout, and stderr
with /dev/null. pt_chown shouldn't print anything when called to
do real work.

Fix sync_file_range on ppc/ppc64.
I've noticed that sync_file_range is a stub on ppc/ppc64.
The kernel on these arches provides sync_file_range2 syscall with swapped
parameters.
The following completely untested patch ought to fix this.

Fix ranges with multibyte characters as endpoints.
This is another bug in computing the fastmap. It was reported by a user
of sed because it usually does not happen with !_LIBC. However, it is
there in that case too.
The bug is that whenever we have a range at the beginning of the regex,
the regex must be tested on any possible multibyte character. The reason
why _LIBC masks it, is that in general there is a collation symbol for
each possible multibyte-character lead byte, so all the lead bytes are
in general already part of the fastmap.
The tests use cyrillic characters as an example. With _LIBC, they pass
without the patch too, but you can make them fail by removing collation
symbols handling.
