sfxge: remove unused common code EFSYS_OPT_RX_HDR_SPLIT
The EFSYS_OPT_RX_HDR_SPLIT optional feature in the common code
implemented the Lookahead Split feature of Windows. This split
received packets at a preconfigured byte offset, and delivered
the header and payload portions to separate receive queues.
Now the common code interface has no callers, so remove it.
Note that this should not be confused with the Header Data Split
feature of Windows, which splits packets at a header boundary.

Go back to using uintptr_t, because code that actually compiles is
infinitely less buggy than code that is theoretically correct in some
alternate universe.
The uintfptr_t type is apparently a freebsd invention, and exists only when
compiling the kernel. It's a little hard to say for sure, since it doesn't
seem to be documented anywhere except in email advice to unsuspecting and
overly-trusting souls, who then get to wear the pointy hat for blindly
following advice without investigating or testing it first.

Restore uart PPS signal capture polarity to its historical norm, and add an
option to invert the polarity in software. Also add an option to capture
very narrow pulses by using the hardware's MSR delta-bit capability of
latching line state changes.
This effectively reverts the mistake I made in r286595 which was based on
empirical measurements made on hardware using TTL-level signaling, in which
the logic levels are inverted from RS-232. Thus, this re-syncs the polarity
with the requirements of RFC 2783, which is writen in terms of RS-232
signaling.
Narrow-pulse mode uses the ability of most ns8250 and similar chips to
provide a delta indication in the modem status register. The hardware is
able to notice and latch the change when the pulse width is shorter than
interrupt latency, which results in the signal no longer being asserted by
time the interrupt service code runs. When running in this mode we get
notified only that "a pulse happened" so the driver synthesizes both an
ASSERT and a CLEAR event (with the same timestamp for each). When the pulse
width is about equal to the interrupt latency the driver may intermittantly
see both edges of the pulse. To prevent generating spurious events, the
driver implements a half-second lockout period after generating an event
before it will generate another.

- Check IP/TCP length before sending the packet to tcp_lro_rx(), if host
does not provide RX csum information (*); and add an option through
sysctl to always trust host TCP segment csum checks (default is off).
- Add sysctl to control the LRO entry depth; it is disabled by default.
It is used to avoid holding too much TCP segments in driver. Limiting
the LRO entry depth helps a lot in a one/two streams RX test.
This one 3x the RX performance on my local test (3Gbps -> 10Gbps), and
~2x the RX performance over a directly connected 40Ge network (5Gbps ->
9Gbps).
(*) It seems the host stops supplying csum information, once the network
load is high. This still needs investigation...
