This commit splits all of the logodefs/graphics out into their own own files
and provides a method for these files to register their logodefs with the
drawer. Graphics are now loaded on demand if they don't exist in the current
set of logodefs.
The drawer module becomes a little easier to navigate through without all of
the graphics mixed in. It's also easy to do one-off graphics like the
9.2 Die Hard tribute by dteske@ without adding even more to our memory
requirements.
- No need for a 'goto' when our entire loop body is then wrapped in a
conditional.
- No need to leave commented out prints laying around
- If an expression is clearly going to be either nil or an expression that
isn't likely to be a boolean, we might as well use `or` to specify a
default value for the expression. e.g. `loader.getenv(...) or "no"`
The previous iteration of this assumed that {module}_load was set. In the
old world order of default loader.conf(5), this was probably a safe
assumption given that we had almost every module explicitly not-loaded in
it.
In the new world order, this is no longer the case, so one could delete a
_load line inadvertently while leaving a _name, _type, _flags, _before,
_after, or _error. This would have caused a confusing Lua error and borked
module loading.
When I implemented my EFI support I failed to check if the upstream version
of makefs in NetBSD had done the same. Override my version with theirs to
make it easier to stay in sync with them in the future.

This fixes a failure to resolve object file paths seen when buildkernel
(which sets MK_AUTO_OBJ=yes) and installkernel (which sets MK_AUTO_OBJ=no)
are run as separate steps. r329232 partially fixed this scenario by removing
MAKEOBJDIR, but it seems the AUTO_OBJ setting also needs to be on the same
page for the build and install steps.

- The two types must be type-punnable for shared members of ifr_ifru.
This allows compatibility accessors to be shared.
- There must be no padding gap between ifr_name and ifr_ifru. This is
assumed in tcpdump's use of SIOCGIFFLAGS output which attempts to be
broadly portable. This is true for all current architectures, but very
large (256-bit) fat-pointers could violate this invariant.

The common pratice in ethernet device drivers is to fall back to
ether_ioctl() to implement generic ioctls not implemented by the driver
and to fail if no handler exists.
Convert these drivers to follow that practice rather than calling
ether_ioctl() for specific cases.
vxge(4) aready had the default case, but it was only called on failure
to match.

If the network interface or the uefi implementation do not support the
ReceiveFilter interface do not return only and just print a message.
U-Boot doesn't support is and likely never will. Also even if this fails
it doesn't mean that network in EFI isn't supported.
The ocs_fc(4) driver supports the following hardware:
Emulex 16/8G FC GEN 5 HBAS
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters
Emulex 32/16G FC GEN 6 HBAS
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters
The driver supports target and initiator mode, and also supports FC-Tape.
Note that the driver only currently works on little endian platforms. It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.

Strip @VER suffices from the LTO output.
This fixes pr36623.
The problem is that we have to parse versions out of names before LTO
so that LTO can use that information.
When we get the LTO produced .o files, we replace the previous symbols
with the LTO produced ones, but they still have @ in their names.
We could just trim the name directly, but calling parseSymbolVersion
to do it is simpler.
This is a follow-up to r331366, since we discovered that lld could
append version strings to symbols twice, when using Link Time
Optimization.
