- needs applying aml_autoscript to work
- add "Reboot from NAND" option to Confluence power menu
- "switch_system" is used for compatibility with old modified bootloaders.

This allows me to have both /dev/env and /dev/nand_env entry and
make fw_printenv/fw_nandenv use the first valid entry

With Amlogic patch the last core would very rarely go online. Revert
this patch to bump performance in high load cases.

projects/Amlogic: add a few aml-specific patches from https://github.com/koying/SPMC and a patch from https://github.com/osmc/osmc to prevent some hangs on reboot

projects/Amlogic: Add a "proper" poweroff kernel patch and allow "powering off" in Kodi. Keep suspend as power key action.

Add it under separate name to not break WeTek builds

Use Amlogic kernel 3.10-cf51189

LZ4 is a lossless compression algorithm, providing compression
speed at 400 MB/s per core, scalable with multi-cores CPU.
It also features an extremely fast decoder, with speed in
multiple GB/s per core, typically reaching RAM speed limits
on multi-core systems.

Benchmark comparison and more info at: https://github.com/Cyan4973/lz4

Automatically compile the script and add to NAND and SD packages.

Move building Amlogic kernel image to scripts to properly re-use a common kernel build

If only one DTB present, add it directly to kernel image

amadec/Makefile: Link amadec with amavutils, otherwise libamcodec will crash during an attempt to use audio decoding

This breaks everything but Amlogic but I don't care.

Allows me to have symlinks in filesystem folders

This allows updating OpenELEC via recovery without wiping userdata
while keeping toothpick method work when a clean flash is needed.
