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
}

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.
