Summary: The new memory leaks analysis is now ready to be enabled by default and turned on in production. This also replaces the biabduction one which is now disabled.

Summary:
This function had been computing the name for ObjC methods wrong, with only the class name. This was causing wrong error messages in Pulse.
The main issue was that `Procname.to_simplified_string` was writing `Classname::methodname` for ObjC methods, which is not the convention. This confused the `hashable_name` funtion. So changing the method name to `Classname.methodname` which is more standard, and this also fixes `hashable_name`.

Summary:
Just like `CFBridgingRelease` we want to be able to model functions that are specific to a given codebase that make a transfer of memory ownership so that developers don't need to worry about releasing that memory anymore, and hence, we don't want to report leaks on that memory.
Things get a little more complicated, because some of the functions we want to model are in a specific namespace, so with this flag we take both cases into account, when we are dealing with namespaces or not.

Summary:
bigmacro_bender
There are 3 ways pulse tracks history. This is at least one too many. So
far, we have:
1. "histories": a humble list of "events" like "assigned here", "returned from call", ...
2. "interproc actions": a structured nesting of calls with a final "action", eg "f calls g calls h which does blah"
3. "traces", which combine one history with one interproc action
This diff gets rid of interproc actions and makes histories include
"nested" callee histories too. This allows pulse to track and display
how a value got assigned across function calls.
Traces are now more powerful and interleave histories and interproc
actions. This allows pulse to track how a value is fed into an action,
for instance performed in callee, which itself creates some more
(potentially now interprocedural) history before going to the next step
of the action (either another call or the action itself).
This gives much better traces, and some examples are added to showcase
this.
There are a lot of changes when applying summaries to keep track of
histories more accurately than was done before, but also a few
simplifications that give additional evidence that this is the right
concept.

Summary:
Unfortunately it is very hard to predict when
`Typ.Procname.describe` will add `()` after the function name, so we
cannot make sure it is always there.
Right now we report clowny stuff like "error while calling `foo()()`",
which this change fixes.
