Add $sort() function

Available overloads:

$sort(<names> [, <flags>])
$sort(<ints> [, <flags>])
$sort(<strings> [, <flags>])
$sort(<paths> [, <flags>])
$sort(<dir_paths> [, <flags>])

The following flag is supported by the all overloads:

  dedup - in addition to sorting also remove duplicates

Additionally, the strings overload also support the following flag:

  icase - sort ignoring case

Note that on case-insensitive filesystem the paths and dir_paths overload's
order is case-insensitive.
