Exemplifying safe use of sysrc(8) has become commonplace in
documentation such as the FreeBSD Handbook. Encourage its use.
Consistency: 'the driver' (not 'this driver').

Note that only firmware for 24xx and 25xx based HBAs is bundled with ispfw(4).
Those get the bundled firmware loaded into the HBAs memory and executed.
All other HBAs will use the firmware from flash.

This patch fixes a bug which prevents building libthr without
_PTHREADS_INVARIANTS defined. The default remains to build libthr
with -D_PTHREADS_INVARIANTS. However, with this patch, if one builds
libthr with WITHOUT_PTHREADS_ASSERTIONS=true then the latency to
acquire+release a default pthread mutex is reduced by roughly 5%, and a
robust mutex by roughly 18% (as measured by a simple synthetic test on a
Xeon E5-2697a based machine).

- Add new DB_DEFINE_TABLE and DB_DECLARE_TABLE macros to define new
command tables. DB_DECLARE_TABLE is intended for use in headers
similar to MALLOC_DECLARE and SYSCTL_DECL.
DB_DEFINE_TABLE takes three arguments, the name of the parent table,
the command name, and the name of the table itself, e.g.
DB_DEFINE_TABLE(show, foo, show_foo) defines a new "show foo" table.
- DB_TABLE_COMMAND, DB_TABLE_COMMAND_FLAGS, DB_TABLE_ALIAS, and
DB_ALIAS_FLAGS allow new commands and aliases to be defined. These
are similar to the existing DB_COMMAND, etc. except that they take
an initial argument giving the name of the parent table, e.g.:
DB_TABLE_COMMAND(show_foo, bar, db_show_foo_bar)
defines a new "show foo bar" command.
This provides a cleaner interface than the ad-hoc use of internal
macros like _DB_SET that was required previously (e.g. in cxgbe(4)).
This retires DB_FUNC macro as well as the internal _DB_FUNC macro.

Improve consistency of the field names with tcpsinfo_t:
* Use mss instead of max_seg_size.
* Use lport and rport instead of tcp_localport and tcp_foreignport.
Use t_flags instead of flags to improve consistency with t_flags2.
Add laddr and raddr, since the addresses were missing when compared

Whilst the kernel can support any number of COMPAT_FOO, world can only
build a single libfoo. Upstream this isn't such an issue, since the only
option is lib32 anyway, but downstreams, such as CheriBSD, may wish to
support multiple at the same time. Thus, adjust the top-level Makefiles
to turn _LIBCOMPAT into a _LIBCOMPATS list that gets iterated over, and
adjust bsd.compat.mk to support this use-case.
For the normal NEED_COMPAT/WANT_COMPAT case, LIBCOMPATFOO remain set and
refer to the requested compat's, preserving the current interface. For
the top-level Makefiles those variables are no longer set (since there
is no longer "the" compat) and only the per-compat ones are available.

The bfe (Broadcom BCM4401 10/100 Ethernet) driver has known bugs and no
active maintenance. There have been no changes other than sweeping tree
changes, typo corrections etc. since 2008 a far as I can tell. Add a
note in the man page so that users expectations are correctly set, and
indicate that it may be removed in the future.
I did not add a gone_in() call in the driver itself as there is no
specific target version for removal, and this driver has evidence of
recent use (dmesg, PRs).
