627cebdb0f zram-swap: set the zram swap priority to 100 by default
New swap devices are added in decreasing priority order, starting at -1. Make
sure the zram swap device has the highest priority, by default.

89e77fb426 zram-swap: robustify mkswap/swapon/swapoff invocation
Instead of assuming /sbin contains the correct BusyBox symlinks, directly invoke
the busybox executable. The required utilities are guaranteed to be present,
since the zram-swap package selects them. Additionally, don't assume busybox
resides in /bin, rely on PATH to find it.

While at it, update the copyright year, use SPDX and switch to AUTORELEASE.

8bdc2362e8 zram-swap: bail out early if the kernel doesn't support swap
Since KERNEL_SWAP is only enabled by default for !SMALL_FLASH targets, we need
to check if the current kernel supports swap before trying to configure
zram-swap, as opkg can't check for kernel dependencies.

Zram switched to per-cpu compression streams since Linux 4.7 [1]. Drop the
irrelevant configuration (no-op).

8205dcaf77 zram-swap: explicitly use mkswap/swapon/swapoff from /sbin
The required BusyBox applets are enabled by default, so we can rely on them
being present in the system. This way, we make sure there are no conflicts
with less featured variants of these same applets which might also be
present in the system.

treewide: bump PKG_RELEASE after replacing which
Bump PKG_RELEASE for the affected packages as replacing "which" by
"command -v" represents a content change.

treewide: replace which with command -v
Fix shellcheck SC2230
> which is non-standard. Use builtin 'command -v' instead.

Using `command -v` is POSIX compliant while `which` is not.  Also to
mention, `command -v` is a shell builtin whereas `which` is a separate
busybox applet.

Once applied to everything concerning OpenWrt we can disable the busybox
feature `which` and save 3.8kB.

package: drop PKG_VERSION for purely local packages
In the package guidelines, PKG_VERSION is supposed to be used as
"The upstream version number that we're downloading", while
PKG_RELEASE is referred to as "The version of this package Makefile".
Thus, the variables in a strict interpretation provide a clear
distinction between "their" (upstream) version in PKG_VERSION and
"our" (local OpenWrt trunk) version in PKG_RELEASE.

For local (OpenWrt-only) packages, this implies that those will only
need PKG_RELEASE defined, while PKG_VERSION does not apply following
a strict interpretation. While the majority of "our" packages actually
follow that scheme, there are also some that mix both variables or
have one of them defined but keep them at "1".

This is misleading and confusing, which can be observed by the fact
that there typically either one of the variables is never bumped or
the choice of the variable to increase depends on the person doing the
change.

Consequently, this patch aims at clarifying the situation by
consistently using only PKG_RELEASE for "our" packages. To achieve
that, PKG_VERSION is removed there, bumping PKG_RELEASE where
necessary to ensure the resulting package version string is bigger
than before.

During adjustment, one has to make sure that the new resulting composite
package version will not be considered "older" than the previous one.

A useful tool for evaluating that is 'opkg compare-versions'. In
principle, there are the following cases:

1. Sole PKG_VERSION replaced by sole PKG_RELEASE:
   In this case, the resulting version string does not change, it's
   just the value of the variable put in the file. Consequently, we
   do not bump the number in these cases so nobody is tempted to
   install the same package again.

2. PKG_VERSION and PKG_RELEASE replaced by sole PKG_RELEASE:
   In this case, the resulting version string has been "version-release",
   e.g. 1-3 or 1.0-3. For this case, the new PKG_RELEASE will just
   need to be higher than the previous PKG_VERSION.
   For the cases where PKG_VERSION has always sticked to "1", and
   PKG_RELEASE has been incremented, we take the most recent value of
   PKG_RELEASE.

Apart from that, a few packages appear to have developed their own
complex versioning scheme, e.g. using x.y.z number for PKG_VERSION
_and_ a PKG_RELEASE (qos-scripts) or using dates for PKG_VERSION
(adb-enablemodem, wwan). I didn't touch these few in this patch.

f4aec13ba4 zram-swap: correctly express the required dependencies
The block-mount swapon implementation doesn't support discard, so make zram-swap
depend only on the default BusyBox implementation or, when unavailable, on the
one present in the swap-utils package.

002cabbae2 zram-swap: enable swap discard
Zram block devices have supported trim/discard for over six years, let's
enable it. This allows the zram device to actually free up allocated memory
when it's marked as unused in the filesystem metadata, as explained in more
detail in the original commit message [1].
