scripts/config: properly report and set string options
Currently, scripts/config removes the leading double-quote from
string options, but leaves the trailing double-quote.
Also, double-quotes in a string are escaped, but scripts/config
does not unescape those when printing
Finally, scripts/config does not escape double-quotes when setting
string options.
Eg. the current behavior:
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Bar \"Buz\" Meh"
$ ./scripts/config -s FOO
Bar \"Buz\" Meh"
$ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Alpha "Bravo" Charlie"
Fix those three, giving this new behavior:
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Bar \"Buz\" Meh"
$ ./scripts/config -s FOO
Bar "Buz" Meh
$ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Alpha \"Bravo\" Charlie"
