`make clean` would fail calling `xcodebuild` to clean. It also calls `ant
clean`. Instead, do the cleaning ourselves by deleting the appropriate stuff so
that it's faster and more reliable.
Also clean the OCaml build before cleaning the tests as that's what more
important most of the time.
Also don't delete the man pages as part of `make clean` as they are checked in.
Also fix ant's Makefile so that the build points at the right .class files (the
path to the .class files was wrong so `make -C infer/tests/build_systems/ant`
would start `ant` for *each* file instead of once).

Switches from opam 1 to opam 2.
Opam2 has some cool new features that simplify some of the scripting.
Notable changes:
1. Use the new `opam lock` *plugin* from https://github.com/AltGr/opam-lock/ instead of https://github.com/rgrinberg/opam-lock. This has a simpler interface for our purposes.
2. Change the way `./build-infer.sh` can be called to use an already existing switch: simply pass `--user-opam-switch` to the script and it won't attempt to create/set the current switch. This can be used to build infer in a local switch for instance.
3. Take advantage of automatic pinning where possible, eg to install infer deps without using opam.locked.

Summary:
New analysis in foetal form to detect invalid use of C++ objects after their
lifetime has ended. For now it has:
- A domain consisting of a graph of abstract locations representing the heap, a map from program variables to abstract locations representing the stack, and a set of locations known to be invalid (their lifetime has ended)
- The heap graph is unfolded lazily when we resolve accesses to the heap down to an abstract location. When we traverse a memory location we check that it's not known to be invalid.
- A simple transfer function reads and updates the stack and heap in a rudimentary way for now
- C++ `delete` is modeled as adding the location that its argument resolves to to the set of invalid locations
- Also, the domain has a really crappy join and widening for now (see comments in the code)
With this we already pass most of the "use after delete" tests from the
Ownership checker. The ones we don't pass are only because we are missing
models.

First step in writing an analyzer that is meant to run only on Android core library implementation.

Strict Mode is an Android debug mode, where doing certain things (like disk read/write or network activity) on the UI thread will raise an exception. We want to statically catch these, as well as indirect versions (the UI thread takes a lock and another thread holding that lock calls a method that would be a strict mode violation).

The previous domain for SIOF was duplicating some work with the generic Trace
domain, and basically was a bit confused and confusing. A sink was a set of
global accesses, and a state contains a set of sinks. Then the checker has to
needlessly jump through hoops to normalize this set of sets of accesses into a
set of accesses.
The new domain has one sink = one access, as suggested by sblackshear. This simplifies
a few things, and makes the dedup logic much easier: just grab the first report
of the list of reports for a function.
We only report on the fake procedures generated to initialise a global, and the
filtering means that we keep only one report per global.

Summary:
With flambda (`-O3`), compilation time is ~5x slower, but the backend is ~25% faster!
To mitigate the atrocious compilation times, introduce a new `opt` build mode in the jbuilder files.
- build in "opt" mode by default from the toplevel (so that install scripts and external users get the fastest infer by default), in "default" mode by default from infer/src (since the latter is only called directly by infer devs, for faster builds)
- `make byte` is as fast as before in any mode
- `make test` will build "opt" by default, which is very slow. Solution for testing (or building the models) locally: `make BUILD_MODE=default test`.
- You can even change the default locally with `export BUILD_MODE=default`.
The benchmarks are to be taken with a sizable pinch of salt because I ran them only once and other stuff could be running in the background. That said, the perf win is consistent across all projects, with 15-20% win in wallclock time and around 25% win in total CPU time, ~9% win in sys time, and ~25% fewer minor allocations, and ~5-10% fewer overall allocations. This is only for the backend; the capture is by and large unaffected (either the same or a tad faster within noise range).

Menu:
1. Write a jbuild file, autogenerated from jbuild.in because we need to fill in
some information at build-time (really, at configure time, but TODO), such as
whether or not clang is enabled.
2. Nuke lots of stuff from infer/src/Makefile that is now in the jbuild file
3. The jbuild file lives in infer/src/ so it can see all the sources. If we put it somewhere else, eg, infer/, then `jbuilder` scans too many files (all irrelevant) and takes 2.5s to start instead of .8s. Adding irrelevant directories to jbuild-ignore does not help.
4. jbuilder does not support subdirectories, so resort to listing all the
source files in the generated jbuild (only source directories need to be
manually listed in jbuild.in though). Still, the generated .merlin is wrong
and makes merlin find source files in _build, so manually tune it to get
good merlin support. We also lose some of merlin for unit tests as it
cannot see their build artefacts anymore.
5. checkCopyright gets its own jbuild because it's standalone. Also, remove
some deprecation warnings in checkCopyright due to the new version of Core from
a while ago.
6. Drop less-used Makefile features (they had regressed anyway) such as
building individual modules. Also, building mod_dep.pdf now takes all the
source files available so they better build (before, it would only take the
source files from the config, eg with or without clang) (that's pretty minor).
7. The toplevel is now built as a custom toplevel because that was easier. It
should soon be even easier: https://github.com/janestreet/jbuilder/issues/210
8. Move BUILTINS.mli to BUILTINS.ml because jbuilder is not happy about
interface files without implementations.
In particular, I did not try to migrate too much of the Makefile logic to jbuilder,
more can be done in the future.

Summary:
This allows the user to specify a different command to build the current version of the project vs to build the previous version of the project. Here's an example:
```
infer diff --gen-previous-build-command-script "echo clang -c hello.c" ... -- clang -c hello2.c
```
By default the two build commands are the same. If the script is to be used for both the current and the previous versions, then it's on the user to run it once first, eg:
```
infer diff --gen-previous-build-command-script "./myscript.sh previous" ... -- $(./myscript.sh current)
```

Summary:
Fixes 2 issues with the build:
- The OCaml dependencies (Version.ml, atdgen-generated stuff, ...) would be generated twice when running `make -j test` from a clean tree, because `make` has no inter-Makefile visibility over common dependencies.
- We would run `atdgen` twice: once for the .ml, once for the .mli, even though one invocation is enough for both.
Add `make ocaml_clean` to nuke only the OCaml code (in particular because
rebuilding the C++ code in the plugin is slow when all I want to get rid of the
OCaml stuff).

Summary:
This messes up with the Buck cache: if infer recaptures a file with only trivial changes that shouldn't affect the capture Buck will still believe it has to reanalyze everything that depends on that file if there's non-deterministic data in infer's output.
Re-use the `--buck` flag used by the Java Buck integration for mostly the same purposes. Add a few special cases for the flavours integration (eg: keep capture data).
Change perf stats registration to take `Config.buck_cache_mode` into account instead of relying on each call site to handle that peculiarity correctly. Also, there's no need to create the perf stats directories before calling the registration function since it will do that too.

Summary:
Introduce `infer-<command>` for each command, except for internal commands
(only `infer-clang` for now) which are not exported. Install these executables
(which are just symlinks to `infer`) on `make install`. The main executable
looks at the name it was invoked with to figure out if it should behave as a
particular command.
Get rid of `InferClang`, `InferAnalyze`, and `InferPrint`. As a bonus, we now
only need to build one executable: `infer`, which should be a few seconds
faster (less link time).
`InferAnalyze` is now `infer-analyze` and `InferPrint` is `infer-print`. To run
`InferClang`, use a symlink named `clang`, `clang++`, etc. to `infer`. There
are such symlinks available in "infer/lib/wrappers/" already.
I also noticed that the scripts in xcodebuild_wrappers/ don't seem useful
anymore, so use wrappers/ instead, as for `make`.

Summary:
Try to read .inferconfig in the current directory, then in .., then in ../..,
etc. This can be overriden with the `INFERCONFIG` environment variable.
This removes the need for two-phase parsing, so clean up that code too.
Paths in .inferconfig are interpreted relative to where .inferconfig is located.
This does not apply to other path-sensitive things like regexpes... this is not
a show stopper because regexpes can account for the fact that infer may be
called from different project roots.
Make sure we fail when .inferconfig exists but cannot be read.
