lualoader: add support for .lua configuration files

If a file is specified in loader_conf_files that ends in '.lua', lualoader
will now load and execute that file. These may be used in place of a
traditional loader.conf to use more complicated logic, where some values
may be set based on others or based on the environment that the C bits has
left us with.

Lua scripts are run in a limited environment. In particular, it does not get
access to any modules or, in-fact, anything except environment variable.

A config.buildenv hook has been added so that a local module can add
whatever it may need to to the environment.

When a global var is set in the lua script, it does not immediately alter
the loader environment. Instead, the script's environment is initially
empty and processed only if the whole script executes successfully.
Effectively, a lua configuration file either takes effect or it does not,
an error will not leave it in a half-baked state.

lualoader: improve the design of the brand-/logo- mechanism

In the previous world order, any brand/logo was forced to pull in the
drawer and call drawer.add{Brand,Logo} with the name their brand/logo is
taking and a table describing it.

In the new world order, these files just need to return a table that maps
out graphics types to a table of the exact same format as what was
previously being passed back into the drawer. The appeal here is not needing
to grab a reference back to the drawer module and having a cleaner
data-driven looking format for these. The format has been renamed to 'gfx-*'
prefixes and each one can provide a logo and a brand.

drawer.addBrand/drawer.addLogo will remain in place until FreeBSD 13, as
there's no overhead to them and it's not yet worth the break in
compatibility with any pre-existing brands and logos.

stand: consolidate knowledge of lua path

Multiple places coordinate to 'know' where lua scripts are installed. Knock
this down to being formally defined (and overridable) in exactly one spot,
defs.mk, and spread the knowledge to loaders and liblua alike. A future
commit will expose this to lua as loader.lua_path, so it can build absolute
paths to lua scripts as needed.

lualoader: Split logodefs out into logo-* files

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.

lualoader: Add primitive hook module, use it to untangle bogus reference

See: comments in the hook module about intended usage, as well as the
introduced use for config.reloaded.

Use the newly introduced hook module to define a "config.reloaded" hook.
This is currently used to register core's clearKernelCache as a reload hook
to avoid a circular dependency and fix this functionality- it didn't
actually work out, and it isn't immediately obvious how it slipped into src.

Other hook types will be introduced into the core lualoader as useful hook
points are identified.
