[PATCH v2 1/2] string-list: Add string_list initializer helper functions

[Tanay Abhra <tanayabh@gmail.com>]

When a compound construct like a string_list within another
struct is used, the default initializer macros are useless.
For such cases add helper functions for string_list
initialization for both DUP and NODUP modes.
