Summary:
Glorious, glorious man pages.
This changes a bunch of things that were hard to break up from the diff, so the
resulting diff is big.
Use `Cmdliner.Manpage` to format man pages (and also format a bit ourselves
since it is so stubborn).
As a bonus, introduce the following subcommands:
```
infer run ... # same as default mode with -- before
infer capture ... # -a capture
infer compile ... # -a compile
infer analyze ... # InferAnalyze
infer report ... # InferPrint
infer diff ... # this one is not new
infer clang ... # InferClang, not that you should use it
```
The man pages can still be improved a lot. Notable missing sections:
`ENVIRONMENT`, stuff about .inferconfig, some example usage, `DESCRIPTION`, ...

Last step for converting thread-safety and quandary to HIL.
Push the logic for managing the id map and converting the instructions into a functor.

Summary:
This is step further simplify the code to avoid cases where the summary of the procedure being analyzed can exist in two different versions:
# one version is the summary passed as parameter to every checker
# the other is a copy of the summary in the in-memory specs table
This diff implements:
# the analysis always run through the `Ondemand` module (was already the case before)
# the summary of the procedure being analyzed is created at the beginning of the on-demand analysis call
# all the checkers run in sequence, update their respective part of the payload and log errors to the error table
# the summary is store at the end of the on-demand analysis call

Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.

Summary:
We waste a lot of space storing the types of field accesses and comparing them sets/maps with access paths.
Yet almost none of the code ever looks at these types (only a tiny piece of code in thread-safety).
If we know the base type, we have enough information to recover the type of the field.
Let's do that instead.

At one point I thought we'd want to have lots of different schedulers for things like exploring loops in different orders, but that hasn't materialized.
Let's make the common use-case simpler by hiding the `Scheduler` parameter inside the `AbstractInterpreter` module.
We can always expose `MakeWithScheduler` later if we want to.

Summary:
When the receiver type and return type of an unknown call are the same, propagate taint to both the receiver and the return type.
This does the right thing for common "builder-style" methods that both update and return the receiver.
We already had custom models for a few such methods (e.g., `StringBuilder.append`), but we can remove them now.

Summary:
Remove the remaining uses of polymorphic equality `=`.
In case of basic types, this is replaced by String.equal or Int.equal.
In case of `= []`, this is replaced by `List.is_empty`.
In case of `= None`, this is replaced by `is_none`.
In case of a datatype definition such as `type a = A | B`,
a `compare_a` function is defined by adding `type a = A | B [@deriving compare]`
and a `equal_a` function is defined as `let equal_a = [%compare.equal : a]`.
In case of comparison with a polymorphic variant `= `Yes`, the equality
defined in `PVariant.(=)` is used. Typically, `open! Pvariant` is added
at the beginning of the file to cover all the uses.

Summary:
A domain should not definite its initial state, since distinct users of the domain may want to choose different initial values.
For example, one user might want to bind all of the formals to some special values, and one user might want the initial domain to be an empty map
This diff makes this distinction clear in the types by (a) requiring the initial state to be passed to the abstract interpreter and (b) lifting the requirement that abstract domains define `initial`.

There's a lot of boilerplate work to be done when adding a new kind of source.
This diff tries to reduce the boilerplate by making a functor do all the work.
The functor:
(1) adds a notion of "footprint kind" to the source
(2) packages the source with a call site

Summary:
We currently can only model the return values of functions as sources.
In order to model inputs of endpoints as sources, we need the capability to treat the formals of certain functions as sources too.
This diff adds that capability by adding a function for getting the tainted sources to the source module, then using that info in the analysis.

Summary:
Previously, summaries worked by flattening the access tree representing the post of the procedure into (in essence) a list of functions from caller input traces to callee output traces.
This is inefficient in many ways, and is also much more complex than just using the original access tree as the summary.
One big inefficiency of the old way is this: calling `Trace.append` is slow, and we want to do it as few times as possible.
Under the old summary system, we would do it at most once for each "function" in the summary list.
Now, we'll do it at most once for each node in the access tree summary.
This will be a smaller number of calls, since each node can summarize many input/output relationships.
