functions.

OK mickey@ and discussed with deraadt@

did NOT approve those for commit.  why did mickey feel he was ok to go
commiting a set of diffs which had not been passed around and tested by people?
we don't know.  mickey, have you got something to say for yourself?

be advertised in this header. Add a comment that this must be in sync
with ld.so. Fixes gdb shared library handing. ok pvalchev@

* manpage related things moved to src/libssl/man/Makefile
* there are now 3 obj directories src/libssl/{crypto,ssl,man}/ instead
of one single src/libssl/obj
* instead of running Configure (with generates lots of symlinks, and
opensslconf.h) this patch stores pre-computed opensslconf.h files
in src/libssl/crypto/arch
* requires a make includes before the library can be built
* libssl and libcrypto can be build separately
(e.g. cd src/libssl/ssl && make obj && make)
* make depend is now supported
* no more symlink trees
tested by miod@ and fries@

what powerpc and sparc64 had as machine/link.h in 3.1 used by gdb, and will
be needed by other ELF architectures to provide gdb solib support; ok drahn

If there is no login.conf or it is corrupt we don't want to make
any assumptions about kerberos.  By request of deraadt@

aliases to fake up strtou?q().  espie@ OK.

open any files, just return an kvm handle that we can use to some
of the functions.

to give them a larger timeslot to do that.
Requested by deraadt@ and various people on icb or vocally.

a.out stuff in link_aout.h and ELF stuff in link_elf.h.
Switch sparc64 back to MI link.h.
drahn@ ok (powerpc will switch soon).

(this will warn if they are used without a terminating NULL pointer.
Note *pointer*, very useful for arches where 0 != (void *)0, in size)
okay millert@

decriptor -> descriptor
authentciated -> authenticated
transmition -> transmission

where each user gets their own file, which is owned by that user.
An old S/Key database may be converted by running "skeyinit -C" as root.
Programs that need to access the S/Key database no longer need to be
setuid root.  They must now be setgid auth instead.

Fixes this for lex and binutils' bfd.
Also, do not install ansidecl.h, we don't really need it, bfd.h uses it,
and we installed it so that bfd worked, so let bfd.h include it directly.
prompted by mickey@

type characteristics.
internal_types.h will contain only settings invisible from standard C, e.g.,
in the __* or _[A-Z]* namespace, and be reused by files like limits.h.
This allows us to shorten machine/limits.h greatly, as all the common defines
are now in sys/limits.h, plus a small stub in internal_types.h.
Tested on all arches as far as I know.
Approved after discussion with art, millert, deraadt, and others.

ok millert@

definitions to allow bsd_auth.h to be included before login_cap.h
or pwd.h.

syntax error if the #define happens before stdlib.h is included.
If abs is #defined, #undef and issue a warning.  This is similar
to what Tru64 UNIX does and is effectively the same as what happens
on Solaris (though on Solaris the real abs() is a macro).
