[PATCH v3] Add test-string-list.c

[Thiago Farina <tfransosi@gmail.com>]

Add a simple test that demonstrates how to create and manipulate
a list of strings using the string-list.h API.

To see the test, call it by:
./bin-wrappers/test-string-list

Or to run it on the git test suite:
cd t && sh t0070-fundamental.sh
