2a11b81090 lualoader: A little more general menu cleanup
Instead of a single-letter parameter ('m'), use something a little more
descriptive and meaningful: 'menudef' ("menu definition") -- these functions
expect to be passed a menudef, so call it what it is.

While here, throw an assertion in that we have a handler for the selected
menu item. This is more of a debugging aide so that it's more obvious when
one is testing a menudef that they've added an entry item that we don't
handle.

This is an improvement over the past behavior of ignoring the unknown menu
entry.

3929cadb65 Take a meat cleaver to defaults/loader.conf
Remove almost all of the _load=XXX options (kept only those relevant
to splash screens, since there were other settings).
Remove the excessively cutesy comment blocks.
Remove excessive comments and replace with similar content
Remove gratuitous blank lines (while leaving some)

We have too many modules to list them all here. There's no purpose in
doing so and it's a giant hassle to maintain. In addition the extra
~500 lines slow this down on small platforms. It slowed it down
so much small platforms forked, which caused other issues...
This is a compromise between those two extremes.

0c38f15ac7 Add NO_OBJ to those directories that don't make anything.
For directories that don't many anything, add NO_OBJ=t just before we
include bsd.init.mk. This prevents them from creating an OBJ
directory. In addition, prevent defs.mk from creating the machine
related links in these cases. They aren't needed and break, at least
on stable, the read-only src tree build.

18a7530938 Greatly reduce the number of #ifdefs supporting the TCP_RFC7413 kernel option.
The conditional compilation support is now centralized in
tcp_fastopen.h and tcp_var.h. This doesn't provide the minimum
theoretical code/data footprint when TCP_RFC7413 is disabled, but
nearly all the TFO code should wind up being removed by the optimizer,
the additional footprint in the syncache entries is a single pointer,
and the additional overhead in the tcpcb is at the end of the
structure.

This enables the TCP_RFC7413 kernel option by default in amd64 and
arm64 GENERIC.

c560df6f12 This is an implementation of the client side of TCP Fast Open (TFO)
[RFC7413]. It also includes a pre-shared key mode of operation in
which the server requires the client to be in possession of a shared
secret in order to successfully open TFO connections with that server.

The names of some existing fastopen sysctls have changed (e.g.,
net.inet.tcp.fastopen.enabled -> net.inet.tcp.fastopen.server_enable).

798caa2ee5 Fix harmless locking bug in tfp_fastopen_check_cookie().
The keylist lock was not being acquired early enough.  The only side
effect of this bug is that the effective add time of a new key could
be slightly later than it would have been otherwise, as seen by a TFO
client.

f0a2d31ab1 Instead of building ofw_iicbus as a separate module, just compile it in to
the iicbus module for FDT-based systems.

The primary motivation for this is that host controller drivers which
declare DRIVER_MODULE(ofw_iicbus, thisdriver, etc, etc) now only need a
single MODULE_DEPEND(thisdriver, ofw_iicbus) for runtime linking to resolve
all the symbols.  With ofw_iicbus and iicbus in separate modules, drivers
would need to declare a MODULE_DEPEND() on both, because symbol lookup is
non-recursive through the dependency chain.  Requiring a driver to have
MODULE_DEPENDS() on both amounts to requiring the drivers to understand the
kobj inheritence details of how ofw_iicbus is implemented, which seems like
something they shouldn't have to know (and could even change some day).

Also, this is somewhat analogous to how the drivers get built when compiled
into the kernel.  You don't have to ask for ofw_iicbus separately, it just
gets built in along with iicbus when option FDT is in effect.

beafe96147 lualoader: Track the menu currently drawn, instead of validity
This cleans up the odd approach to menu drawing. Instead of tracking
validity, we track the menu that was drawn on the screen. Whenever we draw a
menu, we'll set this to that menu.

Anything that invalidates the screen should go ahead and trigger an explicit
redraw, rather than finding a wy to set screen_invalid.

The currently drawn menu is then reset in menu.run as we exit the menu
system, so that dropping to the loader prompt or leaving menu.run() will
just behave as expected without doing redundant work every time we leave a
menu.

fe226a72cb lualoader: Invalidate the screen from menu perspective upon mnu exit
In the common case, this will effectively do nothing as the menu will get
redrawn as we leave submenus regardless of whether the screen has been
marked invalid or not

However, upon escape to the loader prompt, one could do either of the
following to re-enter the menu system:

-- Method 1
require('menu').run()

-- Method 2
require('menu').process(menu.default)

With method 1, the menu will get redrawn anyways as we do this before
autoboot checking upon entry. With method 2, however, the menu will not be
redrawn without this invalidation.

Both methods are acceptable for re-entering the menu system, although the
latter method in the local module for processing new and interesting menus
is more expected.

Cope with this by attempting the allocation with M_NOWAIT and falling back to
the default sizes (with M_WAITOK) if these fail.

ca16d83fd4 lualoader: Pull autoboot handling out into menu.run()
There's no reason for autoboot handling to be mixed in with menu processing.
It is a distinct process that should only be done once when entering the
menu system.

menu.process has been modified to take an initial keypress to process and to
only draw the screen initially if it's been invalidated. The keypress is
kind of a kludge, although it could be argued to be a potentially useful
kludge if there are other processes that may need to feed a keypress into
the menu system.

28384160a7 lualoader: Pull menu redrawing specifics out of menu.process
In general, every menu redraw is going to require a screen clear and cursor
reset. Each redraw also has the potential to invalidate the alias table, so
we move the alias table being used out into a module variable. This allows
third party consumers to also inspect or update the alias table if they need
to.

While here, stop searching the alias table once we've found a match.

da9ab82706 lualoader: Clean up menu handling a little bit
This is driven by an urge to separate out the bits that really only need to
happen when the menu system starts up. Key points:

- menu.process now does the bulk of menu handling. It retains autoboot
  handling for dubious reasons, and it no longer accepts a 'nil' menu to
  process as 'the default'. Its return value is insignificant.
- The MENU_SUBMENU handler now returns nothing. If menu.process has exited,
  then we continue processing menu items on the parent menu as expected.
- menu.run is now the entry point of the menu system. It checks whether the
  menu should be skipped, processes the default menu, then returns.

With r329882, in the absence of a free page shortage we would only take
len(PQ_INACTIVE)+len(PQ_LAUNDRY) into account when deciding whether to
aggressively scan PQ_ACTIVE. Previously we would also include the
number of free pages in this computation, ensuring that we wouldn't scan
PQ_ACTIVE with plenty of free memory available. The change in behaviour
was most noticeable immediately after booting, when PQ_INACTIVE and
PQ_LAUNDRY are nearly empty.
