This will be used to append extra information to images which allows the
system to verify if an image is compatible with the system.
The extra data is appended to the end of the image, where it will be
ignored when upgrading from systems that do not process this data yet:
If the image is a squashfs or jffs2 image, the extra data will land
after the end-of-filesystem marker, where it will be overwritten once
the system boots for the first timee.
If the image is a sysupgrade tar file, tar will simply ignore the extra
data when unpacking.
The layout of the metadata/signature chunks is constructed in a way
that the last part contains just a magic and size information, so that
the tool can quickly check if any valid data is present without having
to do a pattern search throughout the full image.
Chunks also contain CRC32 information to detect file corruption, even
when the image is not signed.

The libblkid probe support in fstools git head requires blkid/blkid.h for
compilation, so add a build dependency on util-linux which provides libblkid.

Commit f5c741b5e0 updated procd to a more recent version, but did not
change the hash of the tar. Update it to the one matching the file on
the download servers.

* Change git packages to xz
* Update mirror checksums in packages where they are used
* Change a few source tarballs to xz if available upstream
* Remove unused lines in packages we're touching, requested by jow- and blogic
* We're relying more on xz-utils so add official mirror as primary source, master site as secondary.
* Add SHA256 checksums to multiple git tarball packages

Enable CONFIG_PROCD_ZRAM_TMPFS compatibility via two changes to list_cpu_idx():
* detect if /tmp is being used by /dev/zram0; if yes, offset initial value by 1 to skip first zram device.
* hot-add /dev/zram1, if not already present.

This reverts commit 763f5d7873.
Currently the vfork() code path in opkg is broken and relies on unsupported
ftello() / fseeko() operations on pipes - we need to restructure the code
before we can reconsider this approach.

src/linksys_bootcount.c misses to include stdint.h.
Apparently musl doesn't mind and includes this header by default,
but glibc does not and causes the build to fail.

sysupgrade immediately reboots after flashing an image and doesn't
allow to unmount filesystems. At least in case the image used for
sysupgrade is stored on a FAT formatted usb flash drive, the following
warning is printed during the next mount of the flash drive:
FAT-fs (sda1): Volume was not properly unmounted. Some data may be
corrupt. Please run fsck.
Although a data corruption during read operations is unlikely, there is
no need to scare the users.

Open/close triggers array around service_triggers call to make using
multiple triggers easier to deal with.
The API was quite confusing, because some functions contained implicit
trigger open/close calls and some didn't.

Fixes duplicate ubiblock entries being listed and improves
find_mount_point to also match against a block device's
major:minor numbers (needed e.g. for /dev/root).

Small cleanup. I initially though /dev/kmsg was used for dmsg(and journald
on desktops) but this seems not to be the case. dmsg is still accessible
as non-root(gives output) which begs the question what does this do? Some
googling reveals that permissions are set to 600 for some embedded systems
while 644 for others. I can't find any justification for the latter. Might
as well err on the side of caution.

This changes the default permissions for /dev entries to be more similar to
a desktop distro. Taken from the defaults of Arch Linux and Ubuntu. Also
changed some that were nonsensical. For example, all 660 permissions on
desktop distros were of the form root:x where x is something other than
root. As such, 660 is useless for LEDE where the specific group is missing.
audio seems to be the only group that isn't.
