Adding an additonal delay after each access to SystemMemory or SystemIO
during autoconf makes no sense.

When a carp interface is created with IFXF_NOINET6 flag, no link-local
address will be created when the vhid (and MAC) is set.  Depending on
the order of the configuration the interface can end up with a ipv6
address, but no v6 link-local and no working neigbor discovery.

Removing this case statement will result in the link-local address
being configured by "ifconfig up" if the inet6 address was configured
before. If you are using inet6 on carp, put an "up" at the end of your
hostname.if. I will work on a better solution at g2k14.

Make normalizeRoundAndPackFloat{32,64} non-static; they will be used outside
of softfloat.c shortly.
Replace the assembly 88100 FPU imprecise exception code (mostly triggered by
denormal results) with C code using softfloat to correctly round the inexact
results in the best possible way according to the current rounding mode.

No functional change intended, and this assembly code was surprisingly almost
non-buggy, as opposed to the precise exception code replaced a few weeks ago;
still an improvement as this replaces 900 lines of arcane assembly with 90
lines of understandable C code.
