Patch from Scott McKellar:

1. In the header: I added compilation guards.

2. In the header: I changed leading double underscores to leading
single underscores.  These identifiers don't appear elsewhere in the
code base, with either double or single underscores.

3. I moved most of the header into the implementation file.  The
headers whose prototypes I moved are now static.  Where there were
comments associated with the prototypes, I moved them to the function
definitions.

4. I removed an extra leading underscore from __osrfRouterFillFDSet().

5. I replaced some deprecated identifiers with their camel-case
equivalents:

   osrf_message_free   ==> osrfMessageFree
   osrf_message        ==> osrfMessage

6. I added the const qualifier to several function parameters.

7. In a couple of spots we were failing to free classname buffers.
I plugged those leaks.
