Summary:
This diff adds a prototype of a new checker that collects config checkings between markers.
Basically, what the checker is doing is a taint analysis.
* Taint source: function calls of "marker start"
* Taint sink: function calls of config checking
* Taint remove: function calls of "marker end"
By the taint analysis, the analysis results will say that which taints can reach to the sink. In other words, which marker ID that has been started can reach to the config checks, before marker's ending.
I am separating the diff into three steps:
(1/3) Add basic abstract semantics
(2/3) Add trace information
(3/3) Add reporting with test examples

Summary:
This models ARC implementation of dealloc, see https://clang.llvm.org/docs/AutomaticReferenceCounting.html#dealloc. Dealloc methods can be added to ObjC classes to free C memory for example, but the deallocation of the ObjC instance variables of the object is done automatically. So here we add this explicitly to Infer:
1. First, we add an empty dealloc method when it is not written explicitly.
2. For each dealloc method (including the implicitly added ones) we add calls to dealloc of the ObjC instance variables.

Summary:
This provides some of the infrastructure needed for documentation issue
types within infer itself so we can generate the website and keep it up
to date when introducing new issue types.
Basically each issue type has documentation in its datatype in OCaml
now. But, documentation strings can be several pages of text! To avoid
making IssueType.ml even more unreadable, add the option to write
documentation in long form in files in infer/documentation/issues/.
This implements `infer help --help-issue-type` and show-cases how
documentation works for a couple of issue types. Next diff bulk-imports
the current website documentation in this form.

Summary:
By and large issues of a given type (eg NULL_DEREFERENCE) are always
reported with the same severity (eg ERROR), but that severity is hard to
tease out from the code. This makes it more explicit by favouring the
default in `IssueType.t` in many cases without changing infer's
behaviour. The checkers typically use `Reporting.log_{error,warning}`;
these are taken care of in the next diff.

Summary:
- "visibility" (whether an issue to report is something to show the user
or something that is only used for debugging or for detecting other
issues) is an intrinsic property of an issue type and thus belongs in
`IssueType.t`.
- "severity" (warning/error/...) is something that each issue should
have a default for ("a memory leak is by default an ERROR", a
"condition always true is by default a warning"), but can also be
overriden at run-time. Right now only nullsafe uses that capability:
when in "strict mode", some warnings become errors. We can imagine
extending this to other issue types, or even providing config flags to
turn warnings into errors, like compilers often have.
To guess the default severity (since it's dynamic it can be hard to know
for sure!), I tried to find places where it was reported as the source
of truth, but also later diffs test these defaults against our tests (by
removing most of the dynamic changes in severity).
With this diff there are 3 places where severity is set:
1. The default severity in IssueType.t: this is unused for now.
2. The severity from `Exceptions.recognize_exception`: this is
semi-statically determined and, if set, takes precedence over number 3 (which looks wrong to me!)
3. The severity passed to `Errlog.log_issue` when we actually add an
issue to the error log: this is used only when (2) is unset.
The next diffs will make 1 the default, delete 2, and make 3 optional
but override 1 when passed.
