`tooltip-identifier-from-point' is only used by gud so `gud-find-c-expr'
will always be defined. Actually, I think the functions that provide
the tooltips for gud should be should really be in gud.el.

The server prefix is described in the Annotations section of the Gdb info
pages.  Annotations have been around for a long time so I presume the server
prefix has too. Eli could probably tell you more.

It has nothing to do with the gdbserver program as far as I know.
