For non-overlay configuration we need checksum for config file that
weren't modified by the user. For OPKG in sysupgrade we check the status
file for the Conffiles: entry of every package. this entry contains
checksum for every static file that the package contains.
Provide the same info for APK by creating a conffiles_static file and
parse this file on sysupgrade for non-overlay configurations.
This is also used by the sysupgrade -u option to exclude non-changed
files from the final backup.

Due to previous refactoring in sysupgrade, writing backup archives to
stdout became impossible since the hardcoded gzip output redirection
did not account for the `-` special case filename.
Fix this issue by substituting `-` with `/proc/self/fd/1` in the tar
archive output path variable.
Also remove a redundant `rm -f` of the target file path that occurs
before the file could've possibly been written.

Replace mount + overlay with manually built tar archive that gets
prepended to the actual config files backup. This allows more
flexibility with including extra backup files. They can be included at
any paths and don't require writing to flash or mounting an overlay

Usage of word "add" was somehow misleading in those functions:
1. They don't really add (as in: append) anything. Result files are
created from scratch.
2. It wasn't clear what adding files means. It could be understood as
adding actual files somewhere (to existing archive?).
Also the word "add" was also a bit ambiguous.

This reverts commit 4fa9aaf0be.
That seemed like a good idea allowing us to include any runtime
generated file in archive. Unfortuantely it broke backups with files
from mounted directories.
When mounting overlay with / as lowerdir its mounts don't propagete in
the mountpoint. That resulted in empty directories:
/tmp/overlay.XXXXXX/backup/tmp/
/tmp/overlay.XXXXXX/backup/var/
/tmp/overlay.XXXXXX/backup/dev/
/tmp/overlay.XXXXXX/backup/proc/
etc.
As some platforms / users try to backup files like /var/dhcp.leases or
/boot/cmdline.txt it means we can't use that solution.

Setting overlay while creating backup allows including extra files in
archive without actually writing them to flash. Right now this feature
is limited to /etc/backup/ directory and is used only for including
installed_packages.txt.
Extend this solution to make it more generic:
1. Always mount overlay while creating backup
2. Overlay whole / to don't limit it to /etc/backup/
This allows including any additional files in backups and adding more
sysupgrade features.

tar stderr was probably discarded only to remove this message:
tar: removing leading '/' from member names
However, together with that, any other error would also be discarded.
It is easier to fix that allowing the error message to be printed.
In sysupgrade, the backup file list only uses absolute paths. That way,
the solution is to remove the leading '/' from all files (sed) and chdir
to / (option -C /)

Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to

This broke initramfs detection which prevents config files from
being saved as it does not work from initramfs.
So, lets test for $(rootfs_type) returning "tmpfs" instead.

With package "coreutil-sha256sum" installed "sysupgrade" fails to perform 'sha256sum -s' and instead returns 'invalid option -- 's''.
This is caused due to:
different syntax for a sha256sum status check ('sha256sum --status' with "coreutil-sha256sum")
'/usr/bin/sha256sum' being symlinked to '/usr/bin/gnu-sha256sum' (after installation of "coreutil-sha256sum")
"coreutil-sha256sum" package from the packages feed replaces the Busybox sha256sum
This patch restores for 'sysupgrade' the busybox call to its sha256sum applet.

So far firmware validation result was binary limited: it was either
successful or not. That meant various limitations, e.g.:
1) Lack of proper feedback on validation problems
2) No way of marking firmware as totally broken (impossible to install)
This change introduces JSON for storing detailed validation info. It
provides a list of performed validation tests and their results. It
allows marking firmware as non-forceable (broken image that can't be
even forced to install).
Example:
{
"tests": {
"fwtool_signature": true,
"fwtool_device_match": true
},
"valid": true,
"forceable": true
}
Implementation is based on *internal* check_image bash script that:
1) Uses existing validation functions
2) Provides helpers for setting extra validation info
This allows e.g. platform_check_image() to call notify_check_broken()
when needed & prevent user from bricking a device.
Right now the new JSON info is used by /sbin/sysupgrade only. It still
doesn't make use of "forceable" as that is planned for later
development.
Further plans for this feature are:
1) Expose firmware validation using some new ubus method
2) Move validation step from /sbin/sysupgrade into "sysupgrade" ubus
method so:
a) It's possible to safely sysupgrade using ubus only
b) /sbin/sysupgrade can be more like just a CLI

Some functions only used by stage2 are moved there from common.sh.
One piece that could still use more cleanup is platform_pre_upgrade: many

we need to evaluate it before the switch; conversely, flash writes happen
in that function on some targets. Targets that do the latter should be
