Hello everyone,

* This is based on Roman Stratiienko's work to support boot image header version 3 and 4.

* This supports the new boot image headers v3, v4 and bootconfig feature.

- Tested on Amlogic Khadas vim3l, a reference board for Android Open Source Project

  And on AM625 Texas Instruments board with 5.10 linux kernel

Main changes :
- New partition : vendor boot, with a specific vendor ramdisk
- DTB is stored in the vendor boot partition
- The generic ramdisk is placed after the vendor ramdisk
- Bootconfig feature support

Here is a link to see the related android boot flow changes on KHADAS vim3l as an example:

Changes in v3:
- Ddd documentation for v3,v4 boot image header
- Add mkbootimg tool to Dockerfile
- Add full comments for functions/structs in include/image.h and include/android_image.h
- Add map_sysmem() to make the boot work on Sandbox
- Rename andr_vendor_img_hdr -> andr_vnd_boot_img_hdr

Changes in v2:
- Rework parts of the code to fix the abootimg test: test_abootimg
- Update test_abootimg to support boot image header v4
- Remove LIBXBC library, import and adapt the functions to support bootconfig feature
- Rename the used structures :
	andr_boot_img_hdr_v0_v1_v2 -> andr_boot_img_hdr_v0
       	andr_boot_img_hdr_v3_v4 -> andr_boot_img_hdr_v3
	andr_vendor_boot_img_hdr_v3_v4 -> andr_vendor_img_hdr
