Summary: When not matching overloads, when the wrong number of arguments is given, instead of just no matching the function, we may want to fail, e.g. for internal-use functions.

Summary:
This was already dead code that didn't know it was dead, doubly so:
1. Only active with `-a biabduction`, which is deprecated
2. Doesn't do anything since it somehow always iterates over an empty list of procedures (I don't really know why that is, but testing shows this is the case)

Summary:
Naming a variable `_foo` makes the compiler not warn about them if they are
unused, but there are lots of instances of such variables in the code where
they are in fact used, defeating the warning and introducing confusion for
those used to this naming convention.
Basically `sed -i -e "s/ _\([a-zA-Z][a-zA-Z0-9_']*\)/ \1_/g" **/*.ml` followed
by manual fixing of compilation errors (lots of `compare__foo` ->
`compare_foo_`).

`infer capture -a checkers ...` would accidentally trigger the analysis phase.
This crashes the Buck flavors integration when used with `--reactive` because

Target patterns/aliases rarely contain only targets supporting infer flavor, so it makes sense to automatically filter kinds with handle in those cases.

To resole #797 this adds runtime option to select VFS for SQLite,
When infer runs on WSL this defaults to "unix-excl" (https://sqlite.org/vfs.html) and if VFS is specified, then WAL is not enabled (since WAL is non compatible with custom VFS - https://www.sqlite.org/wal.html).

We need to use the procedure description of the callees for lazy dynamic dispatch and for the resolution of the lambda. We may also need this information in other analyses, e.g. for RacerD. This diff makes the procedure description of the callees as part of the summary.

Summary:
This diff adds a new way of executing blocks when they are passed as parameters to a method. So far we just skipped the block in this case.
Now we can execute it. Let's demonstrate with an example. Say we have
//foo has a block parameter that it executes in its body
foo (Block block) { block();}
// bar calls foo with a concrete block
bar() {
foo (^(){
self->x = 10;
});
};
Now, when we call the method foo with a concrete block, we create a copy of foo instantiated with the concrete block, which in itself is translated as a method with a made-up name.
The copy of foo will get a name that is foo extended with the name of the block parameter, the call to the block parameter will be replaced to a call to the concrete block, and the captured variables
of the concrete block (self in this case), will be added to the formals of the specialized method foo_block_name.
This is turned on at the moment for ObjC methods with ObjC blocks as parameters, and called with concrete blocks. Later on we can extend it to other types of methods, and to C++ lambdas, that are handled similarly to blocks.
Another extension is to check when the block has been called with nil instead of an actual block, and raise an error in that case.
After this diff, we can also model various methods and functions from the standard library that take blocks as parameters, and remove frontend hacks to deal with that.

Summary:
I was unable to build 0.13 with the current Dockerfile. Changing the Infer version to 0.13 resulted in errors about the ocaml version not being >= 4.05 and < 4.06. When changing the ocaml version I found that the sqlite extension wouldn't compile via opam.
I tried to clean this up a little bit as I went but please let me know if I have reduced it too much. I made sure that everything still worked by running following the Docker steps outlined here http://fbinfer.com/docs/getting-started.html
