Use Nexus style data layout, allow data components on external sdcard and some optimizations and cleanups

Use internal data as in Nexus devices (sdcard0 is emulated) and external sdcard now called sdcard1.

Optional second partition of external sdcard (data1) can be used to store selected data components such as:
app, data, media and dalvik-cache. To do so, one must create a folder with a name of the component/s on data1.

We register sdcard1 as secondary storage allowing built-in asec mechanism to be used to move apps to it.

Also:
* Add misc recovery related settings and coresponding changes to TWRP in order to support above.
* Modify recovery to backup of emulated internal sdcard and apps in asac container.
* Remove duplicated default init.rc code
* Optimize storage, use cache as secondary swap and reuse devlog as cache

To summarize, this patch allows user to encrypt device including sdcard0,
place selected data components on external sdcard and hopefuly provides better performance.

This is a 2nd iteration of the patch in which we go completely Nexus.
We eliminate external sdcard completely and use it as /data that can be fully encrypted.
In addition we perform series of storage layout changes, cleanups and optimizations.

Now to the details:
* Use original "userdata" parititon as /system (60% more space for GAPPS and DEX data).
* Reduce size of primary zram swap by half (Add more RAM).
* Use original "system" as secondary swap (Provide backup swap for smaller zram swap).
* We create pre-odexed build which should allow the following:
  - Avoid usage of userdata for DEX data of system apps and data duplication
  - Avoid encryption of system DEX data (which is public)
  - Allow much faster access from /system partition
  - Allow much faster boot with encrypted data (when data is encrypted,
    dalvik-cache is also and need to be re-created on each boot for asking user's password!)
  - Enable ART-small mode which pre-compiles (into dalvik-cache) only bare minimum of clasees
* Add misc recovery related settings and coresponding changes to TWRP in order to support above.
* Modify recovery related settings (this device tree can be used for building TWRP image)
* Remove duplicated default init.rc code
* General cleanups

This is a 3rd iteration of the patch in which we go completely Nexus.
We eliminate external sdcard completely and use it as /data that can be fully encrypted.
In addition we perform series of storage layout changes, cleanups and optimizations.

Now to the details:
* Use original "userdata" parititon as /system (60% more space for GApps and ODEX data).
* Use original system partiton as /cache.
  This also allow much faster boot with encrypted data (dalvik-cache is available on boot for asking user's password).
* Reduce size of primary zram swap to 96MB since profiling showed this to be sufficient (20% more RAM).
* Use original "cache" partition as secondary swap (to provide backup swap for smaller zram swap).
* We create pre-odexed build optimized for "small" devices which should allow the following:
  - Avoid usage of userdata for DEX data of system apps and data duplication
  - Avoid encryption of ODEX data of system apps
  - Allow much faster access from /system partition
  - Enable ART-small mode which pre-compiles ODEX data for system apps and relocaes to dalvik-cache
    only bare minimum of clasees
* Add misc recovery related settings and coresponding changes to TWRP in order to support above (this device tree
  can be used for building TWRP image)
* Remove duplicated default init.rc code
* General cleanups
