SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks
to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.
Yet more improvements to bsd.README.
It can't be obsoleted because that causes builds with an old
${DESTDIR}/usr/include/kerberosIV/des.h to fail in directories which
have CPPFLAGS+=-I${DESTDIR}/usr/include/kerberosIV so that their #include
of <krb.h> works (and any subsequent #include <foo.h> by <krb.h>).
(Note: gcc3 won't work with a hack such as prepending -I${DESTDIR}/usr/include
before -I${DESTDIR}/usr/include/kerberosIV.)
Affected directories include lib/libkafs, and any thirdparty source
which used a similar -I/usr/include/kerberosIV hack to use <krb.h>.
alter des.h to be friendly with openssl/des.h (you can include both in the
same file)
make libkrb to depend on libdes. bump major.
massage various portioin of heimdal to be friendly with openssl 0.9.7b.
