Summary:
The internal concept of "kind" should in fact be named "severity" to match the convention used by many other tools, whereas the internal concept of "severity", i.e "HIGH", "MEDIUM" and "LOW" was never used and in any case redundant with the concept of "info", "warning", "error".
This diff maps both the "kind" and "severity" fields to value of the form "advice", "info", "warning", and "error" to be able to progressively migrate the code using the "kind" field.

Summary:
It adds relational domains to Inferbo: octagon of Apron and polyhedra of Elina.
- Each Mem domain value includes one relational value containing relations among symbols. The relational values are modified by the `Prune` and `Store` commands.
- Each abstract value includes three symbols, which represent integer value, array offset, and array size of an abstract value.
The relational domain is deactivated by default. Use the `--bo-relational-domain {oct, poly}` option for the activation, though Inferbo with the relational domains does not work at this point because some modifications of Apron and Elina we made has not been applied to their opam repositories yet.

Summary:
`make doc` will use `jbuilder` (which in turn uses `odoc`) to generate the
documentation for infer's modules. This is useful to browse the APIs of infer
and gives a more discoverable place to host more general documentation about
infer's internals.
Besides the actual plumbing necessary to generate the docs, this diff also
- Moves the various infer/src/*/README.md to index.mld files that make it to the generated docs
- Fixes some doc comments that would anger `ocamldoc`

Preparing for the future change, we won't see instructions as lists but as an abstract type.
This change may be a very minor perf regression: does a few more (but bounded by a constant) instructions traversals only for the nodes involving a Printf-like function call, only for the PrintfArgs checker...

Summary:
Attempt at a better naming scheme:
- `Specs.summary` are now `Summary.t`. The `Summary` module (replacing `Specs`) contains the summary of a procedure: the results of all the analyses, etc.
- `Summary.ml` is now `SummaryPayload.ml`. This concerns how each (AI) analysis extracts its payload from the master summary.
- Accordingly, checkers now define a `Payload` module where previously they defined a `Summary` module. The type is also cleaned up to use `t` instead of `payload`, etc.
- Cleaned up some names as a result, for instance `Specs.get_summary` -> `Summary.get`, etc.

Summary:
The abstract interpreter tried to handle exceptional control-flow by propagating the *pre* of a block that threw an exception rather than the *post*.
This was a half-measure that isn't correct when an exception-throwing instruction isn't in the middle of a block.
The handling of exceptions wasn't actually used anywhere and was leading to further hacks in `ProcCfg`, so let's get rid of it.
