Add a new flag that will remove escape characters after splitting
the string.
This implements a special kind of backslash escaping. It's not C escape
sequences (like '\n' or '\020'), but simply to take the special character
following the backslash verbatim. Note that the backslash is only
considered special, if it's followed by a delimiter, another backslash,
or a whitespace (in combination with %NM_UTILS_STRSPLIT_SET_FLAGS_STRSTRIP).
The main purpose of this form of escaping is nmcli's list options, like
$ nmcli connection modify "$PROFILE" +ipv4.routing-rules 'priority 5 from 192.168.7.5/32 table 5, priority 6 iif a\, from 192.168.7.5/32 table 6'
It's a contrieved example, but the list options are a list of IP
addresses, rules, etc. They implement their own syntax for one element,
and are concatenated by ','. To support that one element may have
arbitrary characters (including the delimiter and whitespaces), nmcli
employs a tokenization with this special kind of escaping.
