Huge thank you to @drebrez for his amazing work on this PR!
* Add generation of initramfs-extra with additional binaries
Extract both initramfs with `pmbootstrap initfs extract`
Add new splashscreens for missing partitions/files errors
Changes in init script:
- use busybox findfs applet to find boot partition
- mount boot partion
- extract initramfs-extra
- show error splashscreens accordingly and loop forever
- start usb unlock directly from unlock_root_partition (hook removed)
* Print out a text message for serial debugging in case of errors
Add initramfs-extra files to `pmbootstrap initfs ls` output
* Fix trailing whitespace in comment...
* ls: Indicate which initramfs we're looking at / add wiki link
I've rewritten the initramfs-development article to reflect the
changes made in this PR. It will be a good read for someone who
extracted the initramfs and wants to know why we have two files.
