Add two bash arrays, XTRA_RSYNC_{FROM,TO}, defined in
/etc/default/armbian-ramlog, and expand these in the two rsync
invocations in /usr/lib/armbian/armbian-ramlog.
The use of bash arrays simplifies the use of multiple arguments and also
allows for in-band commentary between array elements.
When expanding, safely test for these arrays to exist. This is, sadly,
a little verbose in bash, so, while here, split the rsync invocations to
use line continuations.
Fixes https://github.com/armbian/build/issues/2846
Added 2 configuration parameters to armbian-zram-config.
First paramter (SWAP=) can explicitely disable zram swap (while leaving log and tmp untouched).
Second parameter (TMP_SIZE) can be used to explicitely set tmp ramdisk size.
The behaviour of existing configurations is not changed.
New function activate_zram() to initialize zram devices and parameters.
Changed script to use zramctl to more flexibly establish zram devices to use for log and tmp.
This also fixes issues which result from both armbian-zram-config and armbian-ramlog being hardcoded to use zram0
When using a zram device mounted and formatted as ext4 it should be mounted using
the "discard" option so that the actual allocated memory is freed and returned to
the system when files are deleted.
