loader: provide a features table for binary compatibility advertisement

liblua now provides a loader.has_feature() function to probe the loader
binary for features advertised. name => desc mappings are provided in
loader.features to get a list of all of the features loader *can*
support. core.hasFeature is provided as a shim to loader.has_feature
so that individual consumers don't need to think about the logic of the
loader module not providing has_feature; we know that means the feature
isn't enabled.

The first consumer of this will be EARLY_ACPI to advertise that the
loader binary probes for ACPI presence before the interpreter has
started, so that we know whether we can trust the presence of acpi.rsdp
as relatively authoritative. In general, it's intended to be used to
avoid breaking new scripts on older loaders within reason.

This will be used in lua as `core.hasFeature("EARLY_ACPI")`, while the
C bits of loader will `feature_enable(FEATURE_EARLY_ACPI)`.

liblua: add loader.lua_path

As described previously, loader.lua_path is absolute path where scripts are
installed. A future commit will use this to build paths for dofile in
try_include, rather than the current pcall/require setup that makes it more
difficult to coordinate loader aborts from local.lua -- we do not need the
flexibility of require(), and local.lua is in-fact not a 'module-like' file
as we will not be referencing anything from it.

lualoader: Expose loader.parse and add cli_execute_unparsed

This will be used for scenarios where the command to execute is coming in
via the environment (from, for example, loader.conf(5)) and is thus not
necessarily trusted.

cli_execute_unparsed will immediately be used for handling
module_{before,after,error} as well as menu_timeout_command. We still want
to offer these variables the ability to execute Lua-intercepted loader
commands, but we don't want them to be able to execute arbitrary Lua.

liblua: Add loader.interpret

This allows lua to pass back a command string to be executed as if it were
typed at the loader prompt- loader tries to execute the string first as pure

execute it itself.

This will be used to implement menu_timeout_command, among other things,
which *should* be used to execute basic loader commands independent of the
chosen interpreter.

printc does not need the features or the overhead of printf. It does not

Instead, use putc directly. This pipes the string through in its entirety as
a series of 'unsigned char's, generally straight to the console emulator.
