TODO: changes to AOSP for custom android build

AOSP changes TODO

* Support kernel modules

* apple_hid keyboard fixes (swap fn+ctrl, cmd/alt, f_ keys instead of lame brightness and volume shortcuts)

* glibc probably

* package some of my binaries

* add posix 7zip to my binaries

* some of coreutils after I have glibc installed

* CHANGE UMASK on /storage/emulated/0 (sdcard) to allow executing binaries

* libfuse

* openssh (ssh + scp + sshd(?))
----SSHFS

* add /sdcard/lib to $LD_LIBRARY_PATH and/or ld.so.conf, and add /sdcard/bin to $PATH.

* webDAV mounting(?)

* USB OTG mounting (is there a good simple FOSS way? Maybe already in the kernel?)
