tcp: improve handling of segments in TIME WAIT
The check for excluding duplicate ACKs needs to consider only TH_SYN
and TH_FIN. We know that TH_ACK is set and TH_RST is cleared. All
other flags, in particular TH_ECE, TH_CWR, and TH_AE needs to be
ignored for the check.

When TCP ECN decides it wants to assure an ACK is sent it needs to do it correctly and with some limits.
So in testing I have found two interesting cases where ECN is going
to make it so that an ack will be sent right away. These cases need
to be limited to being in the ESTABLISHED state. You don't want ECN
sending ACK's when we are transitioning in front or end states.
Also we don't start a delayed ack timer <and> at the same time set
the ACKNOW flag, thats just plain wrong.

mpool/mpool_get.c: Avoid clobbering 'errno' when handling 'pread' errors
POSIX.1-2024 states that the 'free' function "shall not modify errno if
ptr is a null pointer or a pointer previously returned as if by malloc()
and not yet deallocated". However this is a fairly recent addition
and non-compliant allocators might still clobber 'errno', causing
'mpool_get' to return the wrong error code. Fix this by saving
and restoring 'errno' after calling 'free'.

asmc: introduce the concept of generic models
Having to enter in each of the models for Apple hardware, recompiling,
etc, is tedious. Provide generic models so end-users can leverage some
of the capabilities provided by the driver, i.e., common features like
minimal fans and lights (if present on the generic model) support.
The generic models are as follows:
- Macmini
- MacBookAir
- MacBookPro
- MacPro
This sort of follows the pattern established by the `applesmc` driver in
Linux.

asmc: add Wake-on-LAN control via sysctl
Apple Mac systems support Wake-on-LAN from powered-off state (S5/G2) via
the AUPO SMC key.
This change adds a convenience sysctl, `dev.asmc.0.wol`. This can be
disabled if set to 0 and enabled if set to 1.
The AUPO key is volatile and resets to 0x00 on every boot, so WoL must
be manually enabled before each shutdown to work from powered-off state.
Users need to run: `sysctl dev.asmc.0.wol=1` before shutting down the
system. The sysctl is best set to persist in `/etc/sysctl.conf`.
