The debugger's API mode added a lot of extra complexity to the debugger client for minimal value. It also had a bunch of bugs, and unnecessarily tied alternate debugger clients to the command line client implementation. Deleting it.
Differential Revision: D912729
break start/end/psp currently always report themselves as unbound. If the client is connected to a sanbox, these should instead be treated as bound. Also, break clear all currently removes breakpoints without running their destructors in the right order, which causes the break point counter to not reset to 1.
Added some test cases. Also now permit caller=>func() type of breakpoints. To make this work, I added a method, getCallingSite, to class InterruptSite and use this to walk the stack when checking if a site matches a break point that has more than one function name.
The debugger client now accepts feedback from the the debugger server about whether a breakpoint can be hit, absent further loads of files, classes or functions.
