This ensures uids are stable between edits. This is important for features such as project-wide occurrences that first identify definitions' uids before looking them up in an external table. We need these uids to coincide with the ones of emitted by the compiler.

Since some tables use uids as keys, we have to clean them properly. This is done using the Stamped_hashtable datastructure introduced in 147f0c3.

  + merlin binary
    - Support project-wide occurrences queries using index files (ocaml/merlin#1766)
      - The file format is described in library `Merlin_lib.index_format`
      - Two new configuration directives are introduced:
        - `SOURCE_ROOT` that is used to resolve relative paths found in the
          indexes.
        - `INDEX` that is used to declare the list of index files Merlin should
          use when looking for occurrences.
    - A new `UNIT_NAME` configuration directive that can be used to tell Merlin
      the correct name of the current unit in the presence of wrapping (ocaml/merlin#1776)
    - Perform incremental indexation of the buffer when typing. (ocaml/merlin#1777)
    - `merlin-lib.commands`: Add a `find_command_opt`` alternative to
      `find_command` that does not raise (ocaml/merlin#1778)
    - Prevent uid clashes by not returning PWO for defs located in the current
      interface file (ocaml/merlin#1781)
    - Reset uid counters when restoring the typer cache so that uids are stable
      across re-typing (ocaml/merlin#1779)
    - Improve the behavior on occurrences when the cursor is on a label /
      constructor declaration (ocaml/merlin#1785)
  + editor modes
    - emacs: add basic support for project-wide occurrences (ocaml/merlin#1766)
    - vim: add basic support for project-wide occurrences (ocaml/merlin#1767, @Julow)

[new release] ocaml-index (1.0)

CHANGES:

### Added

- Initial release.
- The `aggregate`` command that finishes reduction of shapes in cmt files and
