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
}

heimdal: Fix multiple security vulnerabilities

The following issues are patched:

- CVE-2022-42898 PAC parse integer overflows
- CVE-2022-3437 Overflows and non-constant time leaks in DES{,3} and arcfour
- CVE-2021-44758 NULL dereference DoS in SPNEGO acceptors
- CVE-2022-44640 Heimdal KDC: invalid free in ASN.1 codec

Note that CVE-2022-44640 is a severe vulnerability, possibly a 10.0
on the Common Vulnerability Scoring System (CVSS) v3, as we believe
it should be possible to get an RCE on a KDC, which means that
credentials can be compromised that can be used to impersonate
anyone in a realm or forest of realms.

Heimdal's ASN.1 compiler generates code that allows specially
crafted DER encodings of CHOICEs to invoke the wrong free function
on the decoded structure upon decode error. This is known to impact
the Heimdal KDC, leading to an invalid free() of an address partly
or wholly under the control of the attacker, in turn leading to a
potential remote code execution (RCE) vulnerability.

This error affects the DER codec for all extensible CHOICE types
used in Heimdal, though not all cases will be exploitable. We have
not completed a thorough analysis of all the Heimdal components
affected, thus the Kerberos client, the X.509 library, and other
parts, may be affected as well.

This bug has been in Heimdal's ASN.1 compiler since 2005, but it may
only affect Heimdal 1.6 and up. It was first reported by Douglas
Bagnall, though it had been found independently by the Heimdal
maintainers via fuzzing a few weeks earlier.

While no zero-day exploit is known, such an exploit will likely be
available soon after public disclosure.

- CVE-2019-14870: Validate client attributes in protocol-transition
- CVE-2019-14870: Apply forwardable policy in protocol-transition
- CVE-2019-14870: Always lookup impersonate client in DB

- 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.
