heimdal: Add 64-bit integer support to ASN.1 compiler

Import upstream 19d378f44:

ASN.1 INTEGERs will now compile to C int64_t or uint64_t, depending
on whether the constraint ranges include numbers that cannot be
represented in 32-bit ints and whether they include negative
numbers.

Template backend support included. check-template is now built with
--template, so we know we're testing it.

Tests included.

Also adjusts the generated files:
* asn1parse.c, asn1parse.h (not strictly necessary, but nice to have)
* der-protos.h, which needs a bunch of new prototypes. I copied these
from a der-protos.h generated by the upstream build system, which
uses a perl script for this.
* adjust printf format strings for int64_t. Upstream uses %lld for this,
but that is not portable, and leads to lots of -Werror warnings.

This should fix target-dependent differences between headers generated
by asn1_compile. For example, when cross compiling world from amd64 to
i386, the generated cms_asn1.h header has:

CMSRC2CBCParameter ::= SEQUENCE {
rc2ParameterVersion INTEGER (0..-1),
iv OCTET STRING,
}

while a native build on i386 has:

CMSRC2CBCParameter ::= SEQUENCE {
rc2ParameterVersion INTEGER (0..2147483647),
iv OCTET STRING,
}

These are _both_ wrong, since the source file, cms.asn1, has:

CMSRC2CBCParameter ::= SEQUENCE {
rc2ParameterVersion INTEGER (0..4294967295),
iv OCTET STRING -- exactly 8 octets
}

- 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.
