Update unpackbootimg to verify the Android boot image magic value. It will also search the first 512 bytes for padding.

Change-Id: I490cba05f2bb616a3f64e3271ecaa61eb9e64be8

unpackbootimg: Fix up the padding search in case the magic does not fall on a 8 byte boundary.

Change-Id: I57471f9c2117cd7965b6958ea0aa88e356436da6

unpackbootimg: Fix magic search.

Change-Id: I68470b637556a08e48ff72b7ef8811cba13b04ad

unpackbootimg: apparently mkbootimg no longer accepts hex values

Change-Id: I95a33f7b40470e4500d418d863a65a75e7aa8499

unpackbootimg: Need to also update the written file.

Change-Id: I45faddbae85273c79b2837f97933634b6e70546f

ramdiskaddr is now ramdisk_offset

Change-Id: I3bf83af5f7001f581506dc7fd9b1eb653334ad35

unpackbootimg: remove host LOCAL_MODULE_TAG

Change-Id: I199d680dc5ab8bf50f5be65c29095bf3adade695

unpackbootimg: Add support for device trees

Change-Id: I340eed99d2274a2f4cbaf5a9f27726ff3a9302e5

unpackbootimg: Add support for detecting lz4 compressed ramdisks

This will check for lz4 magic, and if found change the extension of the
file. Else it'll fall back to the default behavior of assuming gzip. This has
been tested with stock LS980 boot images and LS970 boot images for lz4
and gzip respectively.

Change-Id: Ic62b9fe61db4435ecbc52b66db5ffc9b9d79cbb4

unpackbootimg: Add support for second, second_offset and tags_offset.
