Opkg's builtin decompression code is unsuitable to process nested archives as
it uses a single shared state and relies on undefined seek behaviour for pipes.
Rework the extraction logic to use the external gzip command as I/O filter for
decompressing data and remove the builtin inflate code entirely.
This shrinks the final opkg binary by about 4KB and results in less runtime
memory consumption due to efficient use of vfork() and less copy-on-write
operations in the forked child.
Rework by Felix: create a thread that relays data to the gzip process
instead of using a fragile poll loop

Add procd_send_signal which allows to send an optional specified
kill signal to one specified or all instances of a given service.
By default SIGHUP is sent if no signal is specified
Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
Update procd to latest HEAD in order to introduce support for services signals:
- Adds a new service.signal ubus call to send a kill() signal to one or all
running instances of a given service
- Adds a new "reload_signal" property which allows service init scripts to
request procd to send a specific kill() signal on reload, instead of
stopping and restarting running processes
Also fixes some potential memory leaks reported by cppcheck and an environment
variable corruption in the trace command.

To make sure we properly restart services on upgrade we need to
call the prerm script of the old package, in case the init script
changes (or vanishes).

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.

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.

The API was quite confusing, because some functions contained implicit
