The function that uses nextnum expects to return a u_int32_t, not a mere
int, so let's make nextnum a u_int32_t instead.
Note: retained current u_int32_t style, since the rest of the file uses
it.

Because fnmatch has no side effects, we can safely avoid calling fnmatch
if the end result does not matter anyway (the compiler cannot see this,
so it calls fnmatch in the event it has side-effects).

I have several environments, and at least one of them fails to build
because bool is undefined. Since we use bool, always include stdbool.h
rather than relying on any indirect definitions to pull it in.

camcontrol(8) says that -S to start at a different offset implies that

We always start out using the 10-byte version of READ DEFECT DATA, and
then switch to 12-byte when necessary due to errors or data length
requirements. We always need to get the length again when we do this,
and we're always going to be using 12-byte commands from that point
forward. Simplify the logic a bit based on this observation.

Both ic_flags values are unsigned (uint32_t), so cast them to a signed
int to generate a signed result. Both ic_req values are also
unsigned, but since they are uint16_t, they are implicitly promited to
int before the subtraction.

The if_flags and if_cap fields hold a bitmask of flags. If a flag is
the MSB of the field, then the logic in setifflags and setifcap which
uses a < 0 check does the wrong thing (it tries to clear the flag
rather than setting it). Also, trying to use -<FOO> doesn't actually
work as the result is a nop. To fix, stop overloading setifcap and
setifflags and instead add new dedicated action functions clearifcap
and clearifflags for clearing a flag. The value passed in the
argument to the command is now always the raw flag.
This was reported by a GCC warning after raising WARNS:
sbin/ifconfig/ifconfig.c:2061:33: error: integer overflow in expression '-2147483648' of type 'int' results in '-2147483648' [-Werror=overflow]

This change exports interface capabilities using the standard
Netlink attribute type, bitset, and switches `ifconfig(8)` to use
it when displaying interface data.
Bitset comes in two representations. The first one is "compact",
where the bits are exported via two arrays - "mask" listing the
"valid" bits and "values, providing the values for those bits.
The second one is more verbose, listing each bit as a separate item,
with its name, id and value. The latter option is handy when submitting
update requests.
The support for setting capabilities will be added in the upcoming diffs.

This variable was used to print the created interface name in the
atexit(3) handler. The interface name was calculated in the
ifclonecreate() by matching old & new names.
This change alter the implementation the following way:
1) the function responsible for the interface creation (ifcreate_ioctl)
updates all necessary state internally. This removes the need for the
name manipulation hack in wlan_create().
2) As atexit(3) handler does not accept any parameters, explicitly store
the name to print in the ifname_to_print variable read by the atexit(3)
handler.

This is the continuation of the ifconfig cleanup work. This change is
a pre-requsite for the next changes removing some of the global variables.
It will also help in implementing functionality via Netlink instead of ioctl.
No functional changes intended.
* vxlan_cb() was removed as it contained no code
* ioctl_ifcreate() was renamed to ifcreate_ioctl() to follow the other
netlink/ioctl function naming. Netlink and ioctl provide _different_
interfaces and it's not possible to have a unified interface object
that can be filled by either netlink or ioctl implementations. With that
in mind, I'm leaning more to the function_<nl|ioctl> postfix pattern,
than doing ioctl_ or netlink_ prefix.
