They're allocated using standard newbus API,
which means that we rely on miibus to handle the allocation.
Add VSC8504 to the list of supported PHYs, as it is similar enough
to the VSC8501 that is already supported by this driver.

DP83822 is a 10/100 Texas Instruments PHY.
Link status change interrupts are supported by the driver,
however not all boards have the PHY interrupt wired.
Because of that if failure to allocate an IRQ is not treated as an error.

Create a new miibus OFW specific layer leveraging miibus_fdt.c code.
PHY drivers can than read the properties using device_get_property(9) API.
Resource(interrupt) allocation is also supported.
In order to enable this each NIC/switch driver will have to be modified,
because of how miibus is attached to the parent driver.

In some cases we might want to limit the max speed advertised below of what
the PHY is capable of.
This is usually the case when we connect 1G capable PHY to 100M MAC, or when
some exotic physical connection is used.
Add a new mii_maxspeed field to mii_softc and parse it in mii_phy_dev_attach.
Speed limit is normally located in DT.
The property is already parsed in mii_fdt.c, but its value still has to be
passed by the PHY driver.

Delete all the write only variables in CAM. At worst, the only behavior
change would be to prevent core dumps from chasing NULL pointers (though
I think in all these cases the pointers can't be NULL).

Notable changes include:
- Firmware logging support
- Link management flow changes
- New sysctl to report aggregated error counts
- Health Status Event reporting from firmware (Use the new read-only
tunables hw.ice.enable_health_events / dev.ice.#.enable_health_events

Basic signal tests that tests can we deliver a signal via raise() and
can we deliver one via SIGALARM asynchronously.
In addition, tests whether or not on ARM T32 (Thumb) code can interrupt
A32 (normal) and vice versa.
While this test is aimed at ensuring basic qemu signals are working,
it's good to have in the base.

This test failed if ipfw was loaded (as well as pf). pf used the same
tag as dummynet to indicate a packet had already gone through dummynet.
However, ipfw removes this tag, so pf didn't realise the packet had
already gone through dummynet.
Introduce a separate flag, in the existing pf mtag rather than re-using
the ipfw tag. There were no free flag bits, but PF_TAG_FRAGCACHE is no
longer used so its bit can be re-purposed.

The last consumer of if_com_alloc() is firewire. It never fails
to allocate. Most likely the if_com_alloc() KPI will go away
together with if_fwip(), less likely new consumers of if_com_alloc()
will be added, but they would need to follow the no fail KPI.
With this change if_index can become static. There is nothing
that if_debug.c would want to isolate from if.c. Potentially
if.c wants to share everything with if_debug.c.
Move Bjoern's copyright to if.c.

There there are two changes here. First, ofreebsd32_sigreturn
is declared to take a struct osigcontext rather than a struct
ia32_sigcontext3. This type is incorrect, but harmlessly so.
Second, the name of the unimplemented ogetkerninfo changes in
freebsd32_syscallnames.
This avoids the need to keep a freebsd32-specific syscalls.master
in sync with the default ABI. As evidenced by the number of commits
required to sync the two, it is extremely easy for them to get out
of sync due to misunderstandings and user errors.

Add _Contains_ annotations indicating that the data pointed to by a
pointer argument contains types that vary between FreeBSD ABIs. The
supported set is long (including size_t), pointer (including
intptr_t), and time_t. The first two vary between 32- and 64-bit
ABIs. The laste betwen i386 and everything else.
These will be used to detect which syscalls require handling on
particular ABIs.

While we can detect most ABI changes through analysis of
syscalls.master with suitable annotations, to cases are handled
in the core implementation and others have changes that can not be
infered. Add two new config variables syscall_abi_change and
syscall_no_abi_change which override the detected value. Both are
space-seperated lists of syscall names.

On 32-bit architectures, 64-bit arguments are passed in pairs of
registers. On non-x86 architectures these arguments must be in evenly
aligned registers which necessiciates inserting a pad register into the
argument list. This has historically been supported by adding ifdefs
around padded and unpadded syscall defintions in syscalls.master.
In order to enable generation of 32-bit support files from the base
syscalls.master, pull this support in to makesyscalls.lua enabled by
adding pair_64bit to abi_flags.
The changes to sys_proto.h simply add #ifdef PAD64_REQUIRED
around pad arguments in struct <syscall>_args. In systrace_args(),
replace static syscall index values with post-incremented indexs
allowing a simple ifdef around the argument. Under -O1 or higher
code generation is identical. systrace_entry_setargdesc() is a bit
more complicated as we switch on argument indices. Solve this
with some use of define/undef pairs to compute the correct indices.

Replace long-derived types with their abi equivalent where
required by the target ABI. There are two cases:
- All pointers to types that go from 64-bit to 32-bit between the
default ABI and the target ABI.
- Signed arguments that go from 64-bit to 32-bit (these require
sign-extension before passing to general kernel ABIs).
This adds four new config variables: abi_long, semid_t, abi_size_t,
and abi_u_long which default to long, size_t, and u_long respectively.
