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).

Summary:
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.
