Implement -e option. It modifies the output produced by sysctl(8) in
such a way that the name and the value of the variable(s) are separated
with `=' instead of the usual `: '. This is useful for producing output

Fix a (long standing?) bug in ip_output(): if ip_insertoptions() is
called and ip_output() encounters an error and bails (i.e. host
unreachable), we will leak an mbuf. This is because the code calls
m_freem(m0) after jumping to the bad: label at the end of the function,
when it should be calling m_freem(m). (m0 is the original mbuf list
_without_ the options mbuf prepended.)
Make sure the netmask always has an address family. This fixes Linux
ifconfig, which expects the address returned by the SIOCGIFNETMASK ioctl
to have a valid sa_family. Similar changes may be necessary for IPv6.
While we're here, get rid of an unnecessary temp variable.

Add the sysctl "kern.function_list", which currently exports all
function symbols in the kernel in a list of C strings, with an extra
nul-termination at the end.
This sysctl requires addition of a new linker operation. Now,
linker_file_t's need to respond to "each_function_name" to export
their function symbols.
Note that the sysctl doesn't currently allow distinguishing multiple
symbols with the same name from different modules, but could quite
easily without a change to the linker operation. This will be a nicety
to have when it can be used.

Update rtld for the "new" ia64 ABI. In the old toolchain, the
DT_INIT and DT_FINI tags pointed to fptr records. In 2.11.2, it points
to the actuall address of the function. On IA64 you cannot just take
an address of a function, store it in a function pointer variable and
call it.. the function pointers point to a fptr data block that has the
target gp and address in it. This is absolutely necessary for using
the in-tree binutils toolchain, but (unfortunately) will not work with
old shared libraries. Save your old ld-elf.so.1 if you want to use
old ones still. Do not mix-and-match.
