Replace netmgrd

Taken from a cm11 rom, but probably originally came from a sony kitkat
rom
Replace rild/libril

This is temporary.

rild and libril taken from cm11. This is temporary until I pin down
exactly what it is that we need from it.
Replace wlan firmware/cfg
Remove the prebuilt ril binaries
Add the camera hal module and firmware
Add a bunch of camera.qcom dependencies
Final batch of camera additions, change installation method

Loads of additions to get camera working. Some of this probably isn't
needed; it works though.

Also move away from one module per file. There's enough shit here now
that it's impractical. Just PRODUCT_COPY_FILES' it instead.
Fix build.
