such packets and does the right thing

only do vlan-specific processing when needed

o track bpf changes
o eliminate the use of M_PROTO1 for communicating to drivers about tagged
packets
o eliminate the use of IFF_LINK0 for drivers communicating to the vlan code
that they support h/w tagging; replaced by explicit interface capabilities

o fixup bridge support to handle Ethernet header no longer being stripped
o add consistency checks to ether_input to catch problems with the change
in the API; some of these may want to be moved to #ifdef DIAGNOSTIC at a
later time (though they are not too expensive to leave as is)

now expected at the front of the packet a la ether_input

to the MAC address to be installed for the LL address (this is for future
changes to divest struct arpcom from struct ifnet)

architecture, mainly to avoid getting a SIGFPE signal sent
when calling strtod(3) with certain input.
The SIGFPE has been sent because the code was not aware that
a Gradual Underflow is handled in software via traps on the
Alpha architecture, but is not implemented in our Alpha kernel
layer.
With `Sudden_Underflow' defined, strtod(3) should not depend
on Gradual Underflow and adjust its calculations accordingly,
which means that other, more subtle errors than the sending of
SIGFPE could be solved by this.

caused by dynamic PAM modules that call openlog(3) and closelog(3),
e.g. ports/security/pam_pwdfile.
What happened here is that the module first registered its "ident"
with openlog(3), then PAM library unloaded module with dlclose(3),
and the next call to syslog(3) resulted in SIGSEGV.

the specified filename of the log to be rotated is in fact shell glob
pattern. In this case, all files matching this pattern will be rotated
using the same options. Useful in the case when there is no pre-defined
name for the logfiles (e.g. xtradius, samba etc).

o Remove the unwanted smartness in _longjmp() where it compares
the current ar.bspstore with the saved ar.bspstore and restores
ar.rnat based on it. This either avoids saving ar.rnat in the
jmp_buf or is the consequence of not saving ar.rnat. All this
complexity breaks libc_r where we use longjmp() to switch to
different threads and the current ar.bspstore has no relation
to the saved ar.bspstore. Thus: we save ar.rnat in setjmp()
and simply restore ar.bspstore and ar.rnat in longjmp().
This code needs a cleanup.
o Use 32-bit unsigned types for things that really are 32-bit quantities,
not bus_addr_t. These are not the same as a bus_addr_t, so don't use
that here. Harmless on i386, introduced problems on sparc64.

partitions marked as being of type efi. This change adds code to
1. actually run the newfs command at mount time (install.c),
2. display the newfs state on screen (label.c)
3. allow toggling of the newfs state (label.c)
Even though newfs(8)-ing FAT partitions can be of use on i386
machines in general, it has been opted to minimize impact for
now.
