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

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.

exit instead of return if sideload file creation fails

A return here leaves adb sideload in a permanent loop. An exit is

Let minivold run in the recovery se domain

The vold secontext doesn't have enough permissions to allow formatting
volumes. CWM uses minivold directly for this purpose, so go ahead and
let it run in the recovery domain to give it all the permissions needed.

Touch: slot and tracking updates

Discard type A MT slots if type B MT tracking ID sent: Some devices send
an initial ABS_MT_SLOT event before switching to type B events, so
discard any type A state related to slot.

Track whether ABS_MT_TRACKING_ID was seen in the current sequence to
differentiate between vkeys and hardware keys.

fix unnecessarily slow writing of EMMC partitions

These were attempts to write partitions "conservatively" in hopes of
fixing the problems with writing the radio partition on Nexus 4.  They
didn't work (a kernel patch was needed), but got left in.  They make
writing of partitions unnecessarily slow (ie, we really shouldn't need
to sync() after every 4kb).  Roll back most of them, but leave the
verification read-back in.

Tell vold to use the fstype defined in fstab when formatting

available.
