In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.

This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

- Update FreeBSD Heimdal distribution to version 1.5.1. This also brings
several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.

We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.

- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.

- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.

- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.

- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.

- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

Overhaul of kerberos5/ makefiles. Most significant changes are:

- Dropped support for standalone builds, this was only partially
supported anyway, and required so much magic in makefiles that
made life dangerous (e.g., by using the custom yacc rules).

- Got rid of .OBJDIR in makefiles -- makes building of individual
files possible again.

- Made the .x.c transformations -j safe.

- Reprogrammed LDADD to fix static build of some utilities that
was broken.

- Fixed LDFLAGS and DPADD in the WITH_OPENLDAP case -- positively
affects the contents of .depend files.

- Removed redundant .h's from SRCS, only kept those that are
generated.

- libkrb5/ INCS were bogusly installed again with libgssapi/.

- Made build-tools real tools with their own makefiles in
separate directories. This allows us to properly track
their dependencies, etc.

- Faster build, 21% less of makefile code!

Big fixup of the makefiles. Sort out the dependancies so that "make"
without "make depend" works, "make -j N" works, and lists of source
files are made vertical to reduce future diffs.

Fixed "make checkdpadd".

Add (optional, default off) support to kerberos5 for supporting openldap.
Tests with openldap20 where successful whereas openldap21 didn't like
the way hdb-ldap accessed openldap (doesn't like non-bind access).
To activate the support put a USE_OPENLDAP=yes in your make.conf.
The OPENLDAPBASE is also optional and points to /usr/local as default.

Don't copy headers from the source tree to the object tree without
making sure the copies in the object tree are writable. When files
in the source tree are not writable (as would be the case for a p4
tree) then a buildworld -DNOCLEAN will try to copy over the existing
non-writable headers. This fails. Instead we cat the headers with
redirection. This is just one of the possibilities.
