Also specify a lower maximum heap size more in line with other projects and
remove some redundant settings in other gradle.properties files.

Looks like 6G is not enough for an ASAN build when updating the gradle version.
I tried 8G and 16G on try but that's not enough either.

This also:

* Moves the asan job to `b-linux-large` as the `b-linux` builder does not have
  enough memory to run this build.
* Stops running a full build during lints, which is not necessary (and
  sometimes uses more memory than the build runner has, failing the lint).

There were a few API changes, mostly around explicitly creating
Services/Activities/ContentProvider instances, but they were pretty
easy to address.

Sadly, Robolectric doesn't really work with the new aapt2 processing
in Android-Gradle plugin 3.0+ -- see in particular
https://github.com/robolectric/robolectric/issues/3333#issuecomment-324300418
-- so we have to opt-out of the new implementation for now.  Hopefully
plugin 3.1+ will address these issues, which are widespread.

In-process dex is a slight performance win.

This also upgrades `dexcount-gradle-plugin` to 0.7.1.

DONTBUILD NPOTB

--HG--
rename : mobile/android/gradle/gradle.properties => gradle.properties
extra : commitid : 8L4GIKHfAHF

This is a big patch, but it's essentially NPOTB.  The part that is POTB
is ... removing Gradle integration from the build.  I've implemented
|mach gradle-install| as a substitute for the build system stuff; it's
just so much easier to iterate on a mach command than a moz.build and
Makefile.in.

I'm landing this with self-review because this lessens the impact of the
Gradle integration on the build system and because I am the only person
who understands either the old or the new system.

You'll need to run |mach gradle-install| at top level to configure the
new Gradle integration.  But |mach gradle ...| does the right thing
configuration steps too.

This patch rewrites most of the Gradle integration.  The major changes
are:

* all .gradle files move into mobile/android/gradle;
* all the Gradle projects live in the object directory;
* mozconfig exposed to all build.gradle files;
* simplification of Android configuration between build.gradle files;
* support for user-specified version of build tools;
* first steps towards supporting builds from the source directory;
* bumps Gradle to 2.2.1;
* bumps the Android-Gradle plugin to 0.14.4.

This is seemingly a step backwards given that we'd prefer to ship the
.idea directory in the source directory.  But in fact we get closer to
that; it's possible to run ./gradlew in the source directory and get a
reasonable build.  We'll progress with this in time.  The win right now
is that the projects are nested, which makes importing work better on
Linux machines.

Unfortunately IntelliJ 13 and 14 now have conflicting Android-Gradle
plugin version requirements, so we now only support IntelliJ 14.0.2 and
above.
