Summary: Previously we just reported NONEXHAUSTIVE_PATTERN_MATCH, which was (1) not correct because not only patterns can cause nonexhaustive behavior, but also guards, and (2) the Erlang runtime reports errors more precisely, indicating whether the nonexhaustive behavior occurs with `if`, `case`, functions or match expressions.

Summary:
The gist of this diff is a set of Pulse models for the built-ins
that have been put in Sil by the Erlang frontend:
- __erlang_make_nil, for creating an empty list like []
- __erlang_make_cons, for creating a nonempty list like [1|[]]
- __erlang_pattern_fail, which marks that no pattern matched
The models for the first two update the abstract state. The model for
the third generates a reportable error.
The diff also includes a test.
And also a few bugfixes:
- a type ErlangAny was used sometimes instead of ErlangAny*
- a load that was meant to be n=13 was instead n=*13;
changed to (*tmp=13; n=*tmp)
- the Makefile's guard for the rebar build-system test was inside the large
guard for java analyzers; of course, we don't need java to run rebar

Summary:
`SettableFuture.set` invokes callbacks registered prior to the call, which may also try to acquire extra locks. If the called of `set` already holds a lock this creates lock dependencies which may lead to deadlocks.
Here we warn whenever `set` is called under a lock taken in a different source file. This avoids reporting when a class internally manages locks and calls `set`, reasoning that developers will be aware this is happening.

Summary:
This diff adds a new issue type for reporting modifications to immutable fields (when `report-immutable-modifications` is enabled).
The underlying analysis depends on impurity analysis which itself is based on post-processing of pulse's summaries.

Summary:
This diff extends the cost_item json format to print the autoreleasepool_size field. Not yet, there
is no semantics for that code kind, so the results will always be zero with no traces.

Summary: There is now a compilation check for UNAVAILABLE_API_IN_SUPPORTED_IOS_SDK so this check is less useful. Also the check REGISTERED_OBSERVER_BEING_DEALLOCATED is useful only in an old version of iOS.

Summary:
Better API for creating issue types:
- distinguish hidden/normal/dynamic issue types
- normal issue types should always be documented
- add "TODO" to missing documentation
- dynamic issue types are the only ones that can be created outside of
IssueType.ml
I had to document the new CCBM and the resource leak lab exercise to
keep Help.ml happy, did `make doc-publish`.

Summary:
A bug in docusaurus makes relative URLs fail depending on how the page
was accessed, because the URL of a page in docs/ will end in / if
accessed directly or via hyperlink, but that / will be omitted when
clicking on the sidebar. The final / makes all the difference when
interpreting relative URLs so relative URLs are essentially broken.
See https://github.com/facebook/docusaurus/issues/2832 for more details.
This changes URL generation to generate URLs /docs/next/..., and
manually substitute relative URLs that had been written by hand.
Also fix a few other things about outdated links/comments.
Finally, `make doc-publish`.

Summary:
Take all the issue type documentation in the website and add it to infer
itself so it can generate the website (see further diffs).
I mostly generated this diff by writing a script to call from `utop`
with various file lists to do most of the heavy lifting for me and make
sure I didn't forget any issue types: P132800781

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.
