Use RECOVERY_PRE_COMMAND before calling __reboot() recovery

For the Power menu,
frameworks/base/core/jni/android_os_Power.cpp#L180
already uses RECOVERY_PRE_COMMAND if
TARGET_RECOVERY_PRE_COMMAND is defined in the
BoardConfig.mk for a device to make a system() call before
calling __reboot() for recovery. This commit adds
the same thing to the other places that we know we are
getting into recovery using __reboot(), namely,
adb reboot recovery, the reboot binary and init
in the case of errors.

mkbootimg: support longer kernel command lines

We can't simply increase the value of BOOT_ARGS_SIZE since that
would break past binary compatibility; the offset of 'id' would
change. This can cause serious problems with incremental OTA updates.

Instead, define a supplemental field which stores command line
information beyond the first 512 bytes. A value of 1024 was chosen
to keep the total size of struct boot_img_hdr under the smallest
page size of 2048 bytes.

Even if the extra_cmdline field is used, the original cmdline
field is still always NULL-terminated to avoid issues with older
bootloaders that haven't been updated.

init: Fix queue_all_property_triggers with nonexistent properties

Don't queue actions for "on property=*" if the property does not exist.
This fixes the following errors during boot:

    init: property 'sys.powerctl' doesn't exist while
    expanding '${sys.powerctl}'
    init: powerctl: cannot expand '${sys.powerctl}
