Do not wipe block misc on bootloader msg update

When set_bootloader_message_block() is called, it fopens /misc in write
binary mode, wiping all contents other than what is being written. The
bootloader msg structure is only 1024+32+32 bytes, so some manufacturers
store more than just a bootloader msg on /misc. fopen in read+append
mode so that only the bootloader msg is written and the rest of the
partition is left untouched.

Allow custom bootloader msg offset in block misc

Use board define BOARD_RECOVERY_BLDRMSG_OFFSET with a decimal integer
to define a custom offset where the bootloader message should be
read/written.

Set SELinux security contexts correctly for init and services.

Otherwise everything is left running in the kernel domain when
booting recovery.

adbd: switch to su domain when running as root

When adbd runs as root, it should transition into the
su domain. This is needed to run the adbd and shell
domains in enforcing on userdebug / eng devices without
breaking developer workflows.

Use the new device_banner command line option.

recovery: fix building with pointer-to-int errors turned on

Use intptr_t/uintptr_t to cast between pointer and int to allow
building with -Werror=pointer-to-int-cast and
Werror=int-to-pointer-cast turned on.

Cast to char* instead of unsigned int for pointer arithmetic.

add --shutdown_after option to recovery

The "--shutdown_after" option causes recovery to power down the device
on completion rather than rebooting.

Removes the last vestiges of the "--previous_runs" argument, which
doesn't seem to be used for anything.

fix vulnerability in bspatch

Patches with control data tuples with negative numbers in the first

heap.

exit instead of return if sideload file creation fails

A return here leaves adb sideload in a permanent loop. An exit is
more appropriate for this error.
