- It's consistent with product configuration
- The return type of board/product config's main functions
and the arguments to printvars can be changed without
also making a change in the soong repository. (what I'm about

- Removes obsolete TODO

This commit doesn't attempt to replace the filter
calls with anything more idomatic for now.
It also removes the case for filter-out, because
the actual function name is filter_out and wasn't
being used anyways. Even if I were to change it
to filter_out, that would produce buggy results:
ifneq (,$(filter $(TARGET_BUILD_VARIANT), userdebug eng))
endif
ifneq (,$(filter-out $(TARGET_BUILD_VARIANT), userdebug eng))
endif
Both of these would produce:
if g["TARGET_BUILD_VARIANT"] in ["userdebug", "eng"]:
pass

This allows us to use relative paths everywhere.
It also produces more accurate emulation of TOPDIR,
which should be an empty string.

Having soong generate a list of makefiles for mk2rbc
to look through is much faster than having mk2rbc search
itself. Profiling the readLinesFromeFile() function that
reads the list of makefiles shows it takes on the order
of 200 microseconds, much faster than the ~5 seconds
it takes for mk2rbc to search the tree itself.
This CL also allows include statements that are prefixed
with a variable. The concern with this was that there
would be a lot of load statemnts emitted for generic
include statements, causing the generated code to look
ugly, and converting and loading all those files could
cause performance issues. On the performance issues
front, there's already a check that it doesn't result
in over 150 potentially included files. We can lower
that number if necessary, but it's probably good for now.
On the generated code front, while it's true that it's
ugly, it's better to have working but ugly generated
code than refusing to generate anything working at all.
To ensure the soong finder step isn't slowed down due
to having to find a bunch of new makefiles, I profiled
the combination of newSourceFinder and FindSources in main.go:

Currently, mk2rbc is structured around having a global
"receiver" object that accepts all starlarkNodes. As soon
as they are parsed they are added to the receiver.
Returning the parsed nodes to the calling function is more
flexible, as it allows the calling function to restructure
them as necessary. This is the first step to supporting
complicated statements involving $(eval), such as
`$(foreach v,$(MY_LIST),$(eval MY_LIST_2 += $(v)))`

mk2rbc was already searching the whole android tree
for Makefiles, so allowing variable-prefixed include
statements doesn't affect performance on the file searching
front. On the generated code front, there's already a cap
of 150 potentially-included makefiles that prevents the
performance from getting too bad, and it can be lowered
if necessary.

VariableDefinedExpr was under-developed, and would not
take into account if a variable was from the globals
or product config dictionary.
It also always emitted `g.get("VARIABLE") != None`, which
is not correct behavior. In this example makefile:
```
MY_VAR :=
ifdef MY_VAR
$(info MY_VAR is defined)
else
$(info MY_VAR is not defined)
endif
ifdef MY_UNDEFINED_VAR
$(info MY_UNDEFINED_VAR is defined)
else
$(info MY_UNDEFINED_VAR is not defined)
endif
MY_VAR ?= true
MY_UNDEFINED_VAR ?= true
$(info MY_VAR after ?= is $(MY_VAR))
$(info MY_UNDEFINED_VAR after ?= is $(MY_UNDEFINED_VAR))
.PHONY: all
all:
@:
```
We get the output:
MY_VAR is not defined
MY_UNDEFINED_VAR is not defined
MY_VAR after ?= is
MY_UNDEFINED_VAR after ?= is true
So we can see that even if a variable was set, it's considered
not defined if it was set to an empty value. However, ?= works
differently, and does require the != None, so that was left
as is.
Just use a variableRefExpr and rely on the fact
that variables will be truthy if they're defined.

A potentially inherited (via dynamically calculated path) module may in turn
unconditionally load a module that does no exist in a source tree -- it is
not an error if this potentially inherited module is actually never inherited
because its dynamically calculated path will never reference it. Instead of
emitting an uncoditional `load` for a non-existent file (which is going to fail
in the Starlark parser), emit conditional load and a runtime check.

Previously adding an include_top comment would make it apply
for the rest of the file. This was confusing behavior, and
could also cause extra roots to be searched in a situation
like the following:
\#RBC# include_top foo
include $(VAR)/file.mk
\#RBC# include_top bar
include $(VAR)/file.mk
Here the second include would have file.mk from both the foo
and bar directories in its _entry dictionary.

The include_tops hints are global for the whole parse
context (which is probably also something to fix), which
means that if an include_top hint is duplicated there will
be duplicated keys generated in the _entry starlark dictionary.
