Subject: [PATCH v1 1/5] lib/test_bitmap: Excape space symbols when printing input string

test_bitmap_printlist() prints the input string which contains
a new line character. Instead of stripping it, escape that kind
of characters, so developer will see the actual input string
that has been used. Without this change the new line splits
the string to two, and the first one is not guaranteed to be
followed by the first part immediatelly.
