Pending breakpoints

[Nick Roberts <nickrob@snap.net.nz>]

I still think "info break" isn't quite right for pending breakpoints.  This
isn't about previous behaviour, just missing infoemation.  Currently:

   (gdb) b sqrt
   Function "sqrt" not defined.
   Make breakpoint pending on future shared library load? (y or [n]) y

   Breakpoint 1 (sqrt) pending.
   (gdb) info break
   Num     Type           Disp Enb  Address    What
   1       breakpoint     keep y    <PENDING>  sqrt
      (gdb) start
   Breakpoint 2 at 0x804862c: file myprog.c, line 95.
      Starting program: /home/nickrob/myprog 
   main (argc=1, argv=0xbff1d1e4) at myprog.c:95
   95      main (int argc, char **argv) {
   (gdb) info break
   Num     Type           Disp Enb  Address    What
   1       breakpoint     keep y    0xb7f52114 <sqrt+4>
   (gdb) nosharedlibrary 
   (gdb) info break
   Num     Type           Disp Enb  Address    What
   1       breakpoint     keep y    <PENDING>  

and the last "info break" no longer says what the breakpoint is for.  I don't
really know when you would unload the shared library, in practice, but I think
this line should look like the first output from "info break", i.e., include
sqrt.

The patch below does that.  It's a bit of a guess, though, and I've not run
the testuite.
