Also move -c to --cmdline to match the python mkbootimg tool. Remove
the short options for these rarely-used options.
Remove #if 0 cruft from <bootimg/bootimg.h>.

The script prints out the boot image header
contents and extracts the kernel, ramdisk,
second bootloader and recovery DTBO images.

For non-A/B devices, the recovery partition should
be self-sufficient and not depend on any other
partition. Since recovery may need access to devices
added to the DT by overlays(for eg.display), we need to
make sure that the the recovery image also contains
the information from the DTBO image.
The following fields are added to the boot image
header for this purpose:
-boot header version
-header size
-recovery dtbo size
-recovery dtbo address

The parse_int function attempts to interpret the string to detect
base, which leads to it assuming strings starting with 0 are base
8. This obviously fails for certain dates, so use int instead.

Adds operating system version and security patch level to the boot
image header. This change take into use one of the existing unused
fields to preserve compatibility.
Note: All information is packed into a single field, because there
are a lot of existing devices that break if the first unused field
is set to a non-zero value.

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.

By now these sizes are very common, so make sure we support them.

Add the --base flag to mkbootimg and -b flag to fastboot, to allow
the default kernel base address (0x10000000) to be changed.
