Put postmarketOS aports inside pmbootstrap repo Later, the aports folder will probably get split up in its own repository. But right now this is simply convenient.

main/postmarketos-mkinitfs: split mkinitfs funcs (!1123) Split mkinitfs.sh into two files, so the functions (now in mkinitfs_functions.sh) can be sourced in a test. Such a test will be added in the next commit. Move $BINARIES_EXTRA into the get_binaries_extra() function, so its $(find...) does not get executed when sourcing the functions file. Move $BINARIES into get_binaries() too for consistency.

main/postmarketos-mkinitfs: avoid storing initramfs-extra twice (!932) At the moment we store the same initramfs-extra twice on the file system: - /boot/initramfs-<flavor>-extra - /var/cache/postmarketos-mkinitfs/initramfs-<flavor>-extra_<hash> The second copy is exactly the same file, just with the <hash> (for caching) appended to the filename. We can avoid this by appending the hash directly to the filename on the boot partition, i.e. - /boot/initramfs-<flavor>-extra_<hash> This is possible because we only reference initramfs-extra from the main initramfs, and we already replace the path in it dynamically. It will just let the main initramfs load -extra_<hash> instead of just -extra. This saves a few megabytes of disk space on the rootfs.

Improve copy in mkinitfs (#599) 'install' does not properly handle symlinks, it copies the entire file instead of a symlink to it. This PR uses `cp -a` to preserve symlinks. For example, with `install`, the files libc.musl-armhf.so.1 and ld-musl-armhf.so.1 are the same size, despite the fact that in rootfs libc.musl-armhf.so.1 is actually a symlink to ld-musl-armhf.so.1. According to @drebrez research, the initramfs size shrunk from 1 567 930 to 1 168 591.

main/{devicepkg-dev,postmarketos-mkinitfs}: statically generate splash screens (!899) We need to generate the splash screens separately for each device, because they are specific to the device's display resolution. At the moment we do this dynamically during the installation process. This has the advantage that there is no need to re-build all device packages when one of the splash screen is changed (or a new one is added). In reality, however, the splash screens do not change very frequently. On the other hand, generating the splash screens dynamically has signficant disk usage overhead for a minimal ("none" UI) rootfs: The Python interpreter together with the necessary libraries requires about ~60 MB of disk space on aarch64. The splash screens itself require about ~100 KB for 720x1280. This is not necessary if we move the splash screen generation into devicepkg-dev, which is used to build the device package for all devices. Another advantage is that we no longer need the (rather complicated) caching mechanism for splash screens - so we actually end up with less lines than before. rootfs size for samsung-a5ulte ("none" UI): Before: 450M After: 388M (-62M) After this change, every(!) device package needs to be rebuilt once. No changes are necessary in device packages.

mkinitfs: Introduce deviceinfo_append_dtb variable (!387) We don't need to append the dtb to the kernel image in all cases, with e.g. the u-boot bootloader we can load the dtb seperately from the kernel image. Introduce a new variable deviceinfo_append_dtb, if set to "true", append the dtb, otherwise just copy the dtb file to the boot partition. Fixes #260 [ci:ignore-count]

main/postmarketos-mkinitfs: append extra initfs hash to file contents (!983) Partial revert of 24fa68c9 ("avoid storing initramfs-extra twice"). Some people have (rightfully) complained that including the hash in the filename of the initramfs-extra prevents the device from booting whenever the boot partition gets out of sync with the boot image. In general we should assume that those two are in sync, but there is no need to unnecessarily break this if previously booting the outdated extra initramfs worked just fine. At the end, the hash is just an implementation detail for the caching mechanism - we need it when (re-)generating the initramfs, but it does not have to be within the filename. Instead, we can simply append the hash to the file contents. GZIP will simply ignore the trailing garbage. The boot partition will then look like: $ cat /boot/initramfs-<flavor>-extra <GZIP data>d3c7b449c6fc811d97351bbc46852b66 (the hash) This makes the filename of initramfs-extra nice and stable again. It also fixes a regression where the initramfs-extra would no longer get symlinked by "pmbootstrap export" (I was going to fix that in pmbootstrap but now this solution is more appealing...) While we're at it: Make the script more resilient again by writing to a temporary file first, then move it (atomically) to the real path.
