bf3a79274d Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries.  If necessary, this will happen later.

6ccaf050cc Back out all POSIXified *env() changes.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

e7d29627ee Retire rtld-specific Versions.def. Symbols exported by rtld are supposed
to override weak symbols exported by libc, so by definition these two

021deab651 Add support for RFC 2389 (FEAT) and RFC 2640 (UTF8) to ftpd(8).
The support for RFC 2640 (UTF8) is optional and rudimentary.
The server just advertises its capability to handle UTF-8 file
names and relies on its own 8-bit cleanness, as well as on
the backward compatibility of UTF-8 with ASCII.  So uploaded
files will have UTF-8 names, but the initial server contents
should be prepared in UTF-8 by hand, no on-the-fly conversion
of file names will be done.

3. Try to make file rotation more secure by calling unlink(1) on all
new file names before rotating an old file to the new name, rather than
merely calling 'rm -f' on any files that exceed the number of files
to save.

bb01989367 The script mistakenly ignores the entropy_save_sz variable from
rc.conf[.local]. Fix this, and leave the default as 2048.

Update the copyright year to include the present.

Update the assignment of the copyright to be me personally,
instead of "The FreeBSD Project" which is not a legal entity,
and therefore not a proper assignee. My intention remains the
same however, that this code continue to be BSD licensed, and
freely available to anyone that wants it under those terms.
