[llvm] Fix DEMANGLE_ABI for MinGW (#198288)
Exclude MinGW from __declspec(dllimport) like LLVM_ABI in
llvm/include/llvm/Support/Compiler.h does. MinGW auto-exports all DLL
symbols, so __declspec is not needed and causes undefined __imp__
references when linking static libraries.

wtap: use typed rssi and noise floor values
Adjust the rssi and nf arguments to typed int8_t and adjust the maths
for rssi to be consistant with what net80211 expects.

net80211: define a type for rssi values
Due to net80211 keeping values in 0.5dBm relative to the noise floor
an int8_t is not good enough to prevent a double wrap around, which
means the reported rssi values can be wrong (see D50928 or likely
a commit in the future for more information).
In order to address the problem and not break the userspace API,
start by defining a type within the kernel and use that. In a
next step we will then update the int8_t to int16_t to avoid the
problem up to the ioctl code. This will then allow us to work
on the the user space API indepedently (see PR 293016 for possible
impact outside the base system).
No functional changes intended.

fwget: update realtek and intel pci entries
For Realtek we only add new entries.
For Intel the old way of extracting IDs from the driver no longer
works. The new list is shortened as we drop more specific entries
which were already covered by wildcard entries. The new lists are
also sorted within the groups.
There are 4 entries the new driver no longer carries but are still
present in older versions, so we keep them manually.

man: iwlwifi/rtw88/rtw89: update man pages for Linux v7.0 based updates
For all:
- harmonize Copyright/license section according to style.9 and used
SPDX only.
- mention that the current generation of the driver is based on
Linux version 7.0.
- make linuxkpi.4 and linuxkpi_wlan.4 .Xr as the man pages do exist
these days.
iwlwifi: update the card/chipset names supported (while we still can)
iwlwififw: leave a comment only that we can no longer update the
man page and it will be removed in the future.

rtw89: firmware: extend script to extract fwget entries
The so far so consistent (file)names got an outlier so add the
one character longer pattern as well to catch that.
Sponsored by: The FreeBSD Foundation

iwlwifi: firmware: reduce script to extract fwget information
Due to driver changes it is no longer feasible to extract the full
PCI ID / firmware / card type information in one go as we used to
be able to.
We have already changed the way we extract firmware information for
ports and marked the iwlwififw.4 man page as obsolete.
Reduce the script to simply extarct the fwget(8) information and,
compared to the old times, sort each section so diffs will be easier
to see in the future. This was particular helpful this time to make
sure we do not lose entries with the change of technique.
We also keep the script in the best perl spirit to do the job but
not to win a price, especially given it seems we have to change
matters every (other) year.
Given we can no longer extract firmware information for the PCI IDs,
we need to "manually" check against the ports that names match.

Remove -fms-extensions throughout the tree
During a discussion about using -fms-extensions jhb pointed out that
we have them enabled in the kernel for gcc by default (even multiple
times in one part). I had missed all that and clang still failed on
my use case (needing another option).
The original cause for enabling them for our tree back then was that
we needed to support C11 anonymous struct/unions.
Our in-tree gcc 4.2.1, despite later patches, needed the
-fms-extensions to support these even though this was not the expected
use case for that option ( cc4a90c445aa0 enabled it globally for the
kernel).
clang at that time (or at least when it became default for 10.0)
already was fine (with C11).
Any later gcc (4.6.0 onwards) did not need that option anymore, even
when compiled for -std=iso9899:1990 (which does not support anonymous
structs/unions) unless one would add -pedantic (see gcc git 4bdd0a60b27a).

EC2: Don't enable firstboot_pkgs in small flavour
The EC2 "base" flavour installs the devel/py-awscli package at boot
time by default; we don't do this in the "small" flavour, so the
default behaviour was to update the FreeBSD-ports repository and
then do nothing with it.
Turn off firstboot_pkgs by default; if someone is using the "small"
flavour of AMIs and wants to install packages at instance launch
time, they simply need to add 'firstboot_pkgs_enable="YES"' to
/etc/rc.conf (which they must already be editing via user-data, in
order to provide the list of packages they want installed).

Reland "[clang-tidy] Fix crash in misc-static-initialization-cycle" (#198329)
This commit fixes misc-static-initialization-cycle crashing on catch
(...).
Catch-all handlers have no exception declaration, so traversal of
CXXCatchStmt can call TraverseDecl(nullptr). The check previously passed
that null pointer to DeclContext::containsDecl. This commit fixes the
problem by adding a null guard.
Also added `-fexceptions` in the regression test to avoid buildbot
failure.

nlist.3: Add stab(5) Xref
Commit 876a17321c89 removed the a.out Xref as nlist(3) no longer
supports a.out, but this left nlist(3) without a reference to a page
documenting struct nlist.
struct nlist is documented in both a.out(5) and stab(5), so add an Xref
to the latter.
