There's a reason for this actually, which is that it helps keep the 
myriad of random breakpoint types from infecting the rest of GDB.  
Breakpoint types are visible globally, and individual breakpoint types 
are mentioned here and there in the code, but I think it's worthwhile to 
keep the type enumerations / switches in breakpoint.c as much as possible.

There is a pretty good chance that we're going to be doing some 
refactoring on how breakpoint types are handled - people are interested 
in the idea of "tracing watchpoints" (or "watching tracepoints" :-) ) 
for instance - so there's a practical reason to provide interfaces that 
define the net effect of types, rather than requiring callers to know 
aracane details of each.
