Colorize javac errors

You know those multi-line ones that are frequently interspersed with other buld output?
The ones that don't even have the word "error" in them to search for?

This makes them red.

ps2: fix jar_check failures cause by leaving empty stderr files in intermediates dirs
     this is probably not the best place to store stderr before colorizing it if javac
     exits non-zero, but it seems much lighter than mkdiring a bunch of temp directories
     or using sed to mangle the paths to point to per-intermediates directory unique
     temporary file names

Include extra vendor config early.  If RECOVERY_VARIANT is set, use it
to look for the recovery in an alternate path.

Store the base64 release key in the OTA zips

This can be directly grepped in pre-existing package.xml tables
to make sure we're not trying to update to a differently signed
build

releasetools: Properly handle boot images that use dt

Instead of using a prebuilt boot/recovery image, bring the dt image
into the target files package and use it during package creation

build: use /usr/bin/env to call python

Hardcoding the path to python instead of env is not recommended.  This
can break the build in some Linux environments that link /usr/bin/python
to python3.

releasetools: bring back boot.img handling

This is required for galaxysmtd and other devices with custom

This partially reverts "releasetools: Properly handle boot images that use dt"
