if_epair: support IFCAP_MEXTPG
Enable IFCAP_MEXTPG by default, which may bring performance benefits.
Allow it to be disabled, and when disabled assert that we do not receive
any mbufs with M_EXTPG set. This is useful for testing.
Default the tests to disabling MEXTPG support.

pf: fix a crash on sendfile()
The network layer must not pass unmapped (M_EXTPG) mbufs to if_output()
of network interfaces without IFCAP_MEXTPG. pf should convert these
mbufs by mb_unmapped_to_ext() for such interfaces but it didn't.
The problem had occurred on sendfile because sendfile system call
uses unmapped mbufs for the file data.

tests/sendfile_helper: support remote connection
In order to use the sendfile_helper program in a pf test script that
requires non-loopback interfaces, add functionality to sendfile with a
TCP socket that is connected to a remote host.
The behavior for unix sockets and TCP loopback sockets is unchanged.

fwcam: set ISO speed from device link speed
iso_speed was never initialized, defaulting to S100 regardless of the
camera's actual link speed. Some cameras firmwares reject ISO_EN
when the speed field in the ISO_CHANNEL register
does not match their capabilities.
