Add #!/bin/bash to library functions

Currently when these files are opened your editor doesn't know what to
do with them.  Add #!/bin/bash to library functions so that editors,
diff-tools, etc can do syntax highlighting.

There are other ways to skin this cat, such as renaming to ".sh",
adding -* style editor flags, etc.  We had this discussion in DevStack
too, and came to the conclusion the simplest thing that works for
everyone is to just put the #! at the top.
