13ca3c01ec Clean up some .Os macro uses: quotes are not needed, multiple arguments
don't really work if the first one isn't "FreeBSD", and "FreeBSD-Experimental"
isn't an OS name.

5328c7eb7e As previously threatened, clean up the rshd -a option and make it default
on rshd and rlogind.  However, note that:
1: rshd used to drop a connection with -a if the hostname != ip address.
   This is unneeded, because iruserok() does it's own checking.
   It was also wrong if .rhosts had an explicit IP address in it,
   connections would be dropped from that host solely because the DNS was
   mismatched even though it was explicitly intended to work by IP address.
2: rlogind and rshd check the hostname mappings by default now because that
   is what goes into the utmp/wtmp and logs.  If the hostname != ip address,
   then it uses the IP address for logging/utmp/wtmp purposes.  There isn't
   much point logging ficticious hostnames.
3: rshd -a is now accepted (but ignored) for compatability.  If you really
   want to make life miserable for people with bad reverse DNS, use tcpd in
   paranoid mode (which is questionable anyway, given DNS ttl tweaking).

3cc1b1bf9c Old stuff laying around: Don't use a function called getstr(), that has
nasty consequences when the system curses is ncurses as this conflicts
with a ncurses funciton and causes recursion.

3f47c82a7f Fix a bug in the handling of minor version numbers. Formerly, the
rtld would accept the first shared library it found with the right
major version number, even if the minor version number was too low.
If a different version of the shared library with an adequate minor
version number appeared later in the search path, it would not be
found.

Now the rtld searches all locations first looking for a library
with a minor version that is high enough.  Only if such a library
is not found will it fall back to accepting a minor version number
that is too low.  As before, a warning comes out in that case.

This solves some problems encountered when building an older world
on a -current system.

29218d94d3 Fix a bug that showed up when debugging dynamically linked programs.
References from GDB to "printf" and various other functions would
find the versions in the dynamic linker itself, rather than the
versions in the program's libc.  This fix moves the GDB link map
entry for the dynamic linker to the end of the search list, where
its symbols will be found only if they are not found anywhere else.
It was suggested by Doug Rabson, though I implemented it a little
differently.

I personally would prefer to leave the dynamic linker's entry out
of the GDB search list altogether.  But Doug argues that it is
handy there for such things as setting breakpoints on dlopen().
So it stays for now, at least.

Note, if we ever integrate the dynamic linker with libc (which has
several important benefits to recommend it), this whole problem
goes away.

a3bd401942 Don't recognize a file as an a.out shared library unless it has at
least 2 version numbers.  This fixes the bug where the dynamic
linker would try to load an ELF shared library if it found one.

Note, this change also fixes the same thing in "ld", because the
code is shared.

For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name.  I haven't decided what, if anything, to
do about that.

a565ca5920 Implement ldconfig functionality for ELF. The hints are stored in
a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints".
These hints consist only of the directory search path.  There is
no hash table as in the a.out hints, because ELF doesn't have to
search for the file with the highest minor version number.  (It
doesn't have minor version numbers at all.)

A single run of ldconfig updates either the a.out hints or the ELF
hints, but not both.  The set of hints to process is selected in
the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout"
or "-elf" command line option.  The rationale is that you probably
want to search different directories for ELF than for a.out.

"ldconfig -r" is faked up to produce output like we are used to,
except that for ELF there are no minor version numbers.  This should
enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports
even for ELF.

I implemented the ELF functionality in a new source file, with an
eye toward eliminating the a.out code entirely at some point in
the future.

it to sit right...

The __error() hack gave out the wrong address.  It returned the address of
errno in ld.so instead of the address of errno in the main program.  Oops.

The hack is now correct, just in time to be obsoleted by elf.
