wow I can't believe this has been broken for so long

This reverts commit 5f2e724.

This isn't in CM's android_build and androidarmv6's GL ES needs it or rip boot

We're back to this one again.

This reverts commit 6c72379.

Ignoring CyanogenMod/android_bootable_recovery@ad054c6 because it breaks adb completely.

Cheating worked unless you were on the Gingerbread bootloader, as
the serialno was not set to the bdaddr but some other weird string.

This is pretty much the same method that brcm_patchram_plus uses, without
all of the fancy structs and enums... and error checking, but it's hard to do
that without having the code for this stuff, and probably not really necessary
anyway. :D

Also clean up setwifimac

Necessary to fix the CMUpdater/recovery disaster post 4.3 without hacking
away at recovery code as everything assumes this kind of setup.
It's also "mandatory for CM10", so maybe we're a little late here. :D

When (if) the vold switchable pair stuff gets merged this shouldn't be much of
a problem, but I'm sure there are going to be "vocal" users following this change. :(
