build: Introduce project pathmap and use it for qcom variants

The project pathmap tracks the path to the top level of a project.  The
following functions are provided:

 * project-set-path adds an entry.
 * project-set-path-variant adds a "variant" entry.
 * project-path-for retrieves an entry.

To use as a guard in Android.mk:

  ifeq ($(call my-dir),$(call project-path-for,projectname))

To use for include paths in Android.mk:

  LOCAL_C_INCLUDES += $(call project-path-for,projectname)/...

Set project pathmap for qcom project variants.

build: Set QCOM variants for non-QCOM_HARDWARE defined targets

* Nexus devices and others typically do not define the QCOM_HARDWARE
  flag, so the variant path should always default to the AOSP variant.
* Unconditionally set the variant to the AOSP HAL by default.

roomservice: handle GitHub's api changes

while other teams flood their gerrit, we just reformat our device string

GitHub support reply:

Hi Alexander Martinz,

Sorry for the trouble!  Our search folks investigated and it looks like the issue
is how we tokenize repository names.

We're splitting "find7" into 2 separate tokens ("find" and "7"),
so searching for "find7" returns no results like you found.

This is why dropping the "7" works, or if you search for "7" separately,
it works as well:

https://api.github.com/search/repositories?q=user:NamelessRom+android_device+find+7+fork:true

Does that clear things up?
If this is a problem for your build process however, please let us know.

Thanks,
Robert
