2021-03-26Fix Ltac2 `Array.init` exponential overheadJason Gross
Previously, `Array.init` was computing the first element of the array twice, resulting in exponential overhead in the number of recursive nestings of `Array.init`. Notably, since `Array.map` is implemented in terms of `Array.init`, this exponential blowup shows up in any term traversal based on `Array.map` over the arguments of application nodes. Fixes #14011

2019-05-07Integrate build and documentation of Ltac2Maxime Dénès
Since Ltac2 cannot be put under the stdlib logical root (some file names would clash), we move it to the `user-contrib` directory, to avoid adding another hardcoded path in `coqinit.ml`, following a suggestion by @ejgallego. Thanks to @Zimmi48 for the thorough documentation review and the numerous suggestions.
