Optimally, all list types properties in nmcli support proper escaping.
For that, we should use nm_utils_escaped_tokens_*() API.
For now, just change that for policy routes. They were just added recently,
so no change in behavior of released API.
(cherry picked from commit d59f046bb6)
nmcli supports list options (optlist and multilist properties).
These commonly are individual items, concatenated by a delimiter.
It should be generally possibly to express every value. That means, we
need some for of escaping mechanism for delimiters.
Currently this is all inconsistent or no escaping is supported. I intend
to fix that (which will be a change in behavior).
For now, just add yet another style of tokenzing/concatenating list
items in nmcli. This is the style to replace all other styles.

Before:
# nmcli c modify eth666 tc.qdiscs root
Error: failed to modify tc.qdiscs: '(null)' is not a valid kind The valid syntax is: '[root | parent <handle>] [handle <handle>] <qdisc>'.
After:
# nmcli c modify eth666 tc.qdiscs root
Error: failed to modify tc.qdiscs: kind is missing. The valid syntax is: '[root | parent <handle>] [handle <handle>] <kind>'.
There is no reason to validate only in certain cases. Either we
validate, or we don't (always the same).
This is a change in behavior, but the cases should be sensible.
Most GObject properties default to FALSE/NULL/0. In that case, there
is no difference between setting the default or clearing the value.
During
if (_SET_FCN_DO_RESET_DEFAULT (property_info, modifier, value))
return _gobject_property_reset_default (setting, property_info->property_name);
it is correct to reset the default.
However for list-typed properties, we want to clear the list. So,
it should be
if (_SET_FCN_DO_SET_ALL (modifier, value))
_gobject_property_reset (setting, property_info->property_name, FALSE);
The VFs already can be parsed as plain number (to indicate the
ifindex). We should not also support accepting the plain number
as index to be removed.

$ nmcli connection modify "$PROFILE" -ipv4.addresses 1,3
Already before, nmcli would support removing items by index. But only
one number was supported.
- indexes are zero based (as before).
- duplicate indexes or indexes out of bounds are silently ignored.
Maybe certain properties should not support removal by index.
Use new ValueStrsplitMode "VALUE_STRSPLIT_MODE_STRIPPED".
Note that this is not exactly what we did before. For example, empty
tokens are now silently removed.
Also, we accept now whitespace as separators.
Have one function that gets all the nonesense right. "nonesense", because
we have inconsistent behaviors, and the function is supposed to help with
that.
set_fcn() and remove_fcn() are strongly related. They should accept
arguments in the same format, hence the parsing of the arguments should
be done at one place.
In fact, previously the parsing was separate, leading to ugly
inconsistencies:
$ nmcli connection modify "$PROFILE" +vpn.data x=y
$ nmcli connection modify "$PROFILE" -vpn.data x=y
Error: failed to remove a value from vpn.data: invalid option 'x=y'.
or
$ nmcli connection modify "$PROFILE" +ipv4.addresses 192.168.1.5/24,192.168.2.5/24
$ nmcli connection modify "$PROFILE" -ipv4.addresses 192.168.1.5/24,192.168.2.5/24
Error: failed to remove a value from ipv4.addresses: invalid prefix '24,192.168.2.5/24'; <1-32> allowed.
Let set_fcn() handle set-default, set-all, add, and subtract.
Previously, set_fcn() could only append values. Now, pass on the modifier
so that it may append, set all, or reset the default.
These operations are strongly related and should be handled by the same
set_fcn() function.
It's usually not necessary, because _nm_utils_unescape_spaces()
gets called after nm_utils_strsplit_set(), which already removes
the non-escaped spaces.
Still, for completeness, this should be here. Also, because with
this the function is useful for individual options (not delimiter
separate list values), to support automatically dropping leading or
trailing whitespace, but also support escaping them.
A property-info can only have one property-typ-data. That means,
all functions (get_fcn(), set_fcn()) need to either take not
property-typ-data, or they must all accept the same.
That made it hard to mix _get_fcn_nmc_with_default() with setters
that do require a certain property-typ-data. Instead, move the
is_default_func() to the general portion, and let _get_fcn_gobject()
handle it.
