to re-export anything that it imports. This opt-in feature makes a
module behave more like a header, because it can be used to re-export
the transitive closure of a (sub)module's dependencies.

within module maps, which will (eventually) be used to re-export a
module from another module. There are still some pieces missing,
however.

library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).

submodules. This information will eventually be used for name hiding
when dealing with submodules. For now, we only use it to ensure that
the module "key" returned when loading a module will always be a
module (rather than occasionally being a FileEntry).

into a module. This module can either be loaded from a module map in
the framework directory (which isn't quite working yet) or inferred
from an umbrella header (which does work, and replaces the existing
hack).

the umbrella header's directory and its subdirectories are part of the
module (that's why it's an umbrella). Make sure that these headers are
considered to be part of the module for lookup purposes.

map, so long as they have an umbrella header. This makes it possible
to introduce a module map + umbrella header for a given set of
headers, to turn it into a module.
There are two major deficiencies here: first, we don't go hunting for
module map files when we just see a module import (so we won't know
about the modules described therein). Second, we don't yet have a way
to build modules that don't have umbrella headers, or have incomplete
umbrella headers.

the corresponding (top-level) modules. This isn't actually useful yet,
because we don't yet have a way to build modules out of module maps.

Module map files provide a way to map between headers and modules, so
that we can layer a module system on top of existing headers without
changing those headers at all.
This commit introduces the module map file parser and the module map
that it generates, and wires up the module map file parser so that
we'll automatically find module map files as part of header
search. Note that we don't yet use the information stored in the
module map.
