Summary:
OCaml 4.12 added
```
val __FUNCTION__ : string
__FUNCTION__ returns the name of the current function or method,
including any enclosing modules or classes.
```
This diff simplifies ppx_trace using `__FUNCTION__` to obtain the name
of the function containing each call to a `Trace` function. Before
this diff this is done by maintaining a stack of function names
obtained by parsing value binding patterns during preprocessing. This
technique is not entirely robust and does not deal with some cases (if
calls to `Trace` functions appear in some places, preprocessing fails
with an exception).

This diff renames and moves the opam package definition files to
`<package>.opam` in an `opam` directory at the root of the
repository. This enables opam pinning the different packages contained
in the repo. It is necessary for these files to be either at the root
of the repo or in a directory named `opam` at the root of the repo, or
else opam cannot find them.

Summary:
After merging https://github.com/facebook/facebook-clang-plugins/pull/20, we can now use Actions here to download a facebook-clang custom clang Release here and use it to build C Analyzers during CI, as well as Java Analyzers.
1. had to change `matrix.os: macos-latest` to `matrix.os: macOS-latest`. I guess that's what I typed for the fb clang build, and `curl`ing a Release asset is case-sensitive.
2. Add `jq` to installed packages on mac - we need it for parsing GitHub's API responses
3. Add the logic for fetching a release asset (we currently only look for the `"latest"` release) and downloading the properly-named clang based on OS. Then unpack it and update the `opam` files so we build with clang.
Note: I would have used this Action: https://github.com/dsaltares/fetch-gh-release-asset/ for fetching a Release asset, but unfortunately it seems to be in a fairly new state and it's a Docker Action, which means it doesn't support macOS. The logic in the fetch clang step is roughly based off of this action's logic.

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:
The goals are to have all the checker definitions and documentation in one
place (except how to actually run them, since that's not quite the same
concept; for example inferbo is one checker but several analyses depend on its
symbolic execution), and later on to be able to link issues reported by infer
back to the checker that generated them.
This makes apparent that the documentation of our checkers is lacking,
not touching that in this diff.
Not sure if "analysis" would be a better name than "checker" at this
point? For instance "Linters" is one of the checkers, which historically
at least we have not considered to be the case.

Summary:
With this change Travis will build infer on Linux + OSX using the opam file, in
Java mode only to save us from having to compile clang. This doesn't try to run
the tests yet because 1) building infer takes almost all the alloted time so
OSX times out if we ask it to do more; 2) there's some error in Travis when the
tests are run so more work is needed.
I had to change the opam file a bit to reflect some dependency constraints
since the opam build ignores the opam.locked file (which is good because it
will allow us to detect when such incompatibilities arise).

Summary:
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.

- 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.
