70d3ffb47f zram-swap: Add "max compression streams" configuration option
Config option to limit maximum compression streams per zram dev for
multicore CPU's. This could be defined via 'zram_comp_streams' option in
the 'system' section of '/etc/config/system' file or via cli (for e.x.
with 'uci set system.@System[0].zram_comp_streams=2 && uci commit
system'). Default is number of logical CPU cores.

814cae7362 zram-swap: fix number of created zram devices for multicore CPU's
Use only one zram swap device of the specified $size instead of
[N x $size] devices for multicore CPUs Now zram module uses multiple
compression streams for each dev by default, so we do not need to create
several zram devs to utilize multicore CPUs.

9edc1fe8ab zram-swap: fix zram dev reset for multicore cpu devices
* "zram stop" could reset up to $(num_of_cores) zram devices even if
   some of those were not mounted as swap dev's. This fix tries to
   enumerate mounted swap zram dev's before making a reset

 * remove hot-added zram devs on stop (except zram0)

b9e89adfb7 zram-swap: compression algorithm configuration option
Compression algorithms for zram are provided by kernel crypto API, could
be any of [lzo|zl4|deflate|<some_more>] depending on kernel modules.
Compress algo for zram-swap could be defined via 'zram_comp_algo' option
in 'system' section of '/etc/config/system' file, or via cli (for e.x.
with 'uci set system.@System[0].zram_comp_algo=lz4 && uci commit
system'). check available algo's via 'cat /sys/block/zram0
/comp_algorithm'

f362dc154d zram-swap: CONFIG_PROCD_ZRAM_TMPFS compatibility
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.

c10d97484a Add more license tags with SPDX identifiers
Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.
