- Use 32-bit function alignment as GCC does when using UltraSPARC I or
higher optimizations.
- Don't waste delay slots when possible.
Unfortunately, this still doesn't make libcompiler_rt a viable replacement
for libgcc on sparc64 though as once installed instead, buildworld times
increase by nearly 60% (which isn't related to these assembler functions).

Unfortunately, the ABI was broken upstream for the 4.2 release, which we
imported. We then shipped the broken version for several years and certain
ports (e.g. libobjc2) depend on it, so we're stuck with it for now...
We should revisit this for 10.0, since we're allowed to break the ABI then, but
until then we should keep the ABI we shipped with 8.x and 9.x.

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.

Make our handling of MMX x SSE closer to what gcc does:
* Enabling sse enables mmx.
* Disabling (-mno-mmx) mmx, doesn't disable sse (we got this right already).
* The order in not important. -msse -mno-mmx is the same as -mno-mmx -msse.
Some configure scripts depend on this.

When ntp switched between PLL and FLL mode it produced a log message
"kernel time sync status change %04x". This issue is reported in ntp
bug 452[1] which claims that this behaviour is normal and the log
message isn't necessary. I'm not sure exactly when it was removed, but
it's gone in the latest ntp release (4.2.6p5).
