parameter-framework: add shrinked version of boost ASIO

Boost ASIO is a dependancy of Parameter framework v3.2.4.
As only used by PFW, as not provided by AOSP and as it is a quite huge
library, this patch adds the dependancy within PFW folder as a shrinked
version.

Bug: 22887211

+# Then, run this script by passing it a list of lunch targets. ASIO will be
+# minified based on which files were used when building the Parameter Framework

+This version of ASIO has been minified for lower disk footprint for Android
+integraton by support/android/asio/asio_shrinker.sh.
+
+Although unlikely (thanks to having been tested on all AOSP lunch targets), if
+the Parameter Framework fails to compile on your lunch target because of a
+missing ASIO header, you may download a vanilla ASIO version from
+'http://sourceforge.net/projects/asio/files/asio/1.10.6%20%28Stable%29/' and
+run that script anew.
