84dae82fd3 REST API: Add batch support for posts and terms controllers.
This also exposes the value of `allow_batch` in `OPTIONS` requests to a route.

A future commit will add batch support to more resources.

Props spacedmonkey, chrisvanpatten.
See #53063.

c0995319f4 REST API: Support custom namespaces for taxonomies.
While a taxonomy can define a custom route by using the rest_base argument, a namespace of wp/v2 was assumed. This commit introduces support for a rest_namespace argument.

A new rest_get_route_for_taxonomy_items function has been introduced and the rest_get_route_for_term function updated to facilitate getting the correct route for taxonomies.

For maximum compatibility sticking with the default wp/v2 namespace is recommended until the API functions see wider use.

Props spacedmonkey.

bac6e41c85 REST API: Support custom namespaces for custom post types.
While a custom post type can define a custom route by using the `rest_base` argument, a namespace of `wp/v2` was assumed. This commit introduces support for a `rest_namespace` argument. 

A new `rest_get_route_for_post_type_items` function has been introduced and the `rest_get_route_for_post` function updated to facilitate getting the correct route for custom post types.

While the WordPress Core Block Editor bootstrap code has been updated to use these API functions, for maximum compatibility sticking with the default `wp/v2` namespace is recommended until the API functions see wider use.

56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

0860bb2771 Docs: Remove @access notations from method DocBlocks in wp-includes/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

c6f8182eb0 REST API: Merge similiar error message strings in the Terms Controller.
Replaces the "doesn't" contraction with "does not" to be consistent with similar strings in `WP_Error` messages when a specified term or parent term is missing in `WP_REST_Terms_Controller`.

5b39869860 REST API: Improve the rest_*_collection_params filter docs and fix the terms filter.
The `rest_{$taxonomy}_collection_params` filter in 4.7 is incorrectly using
single quotes instead of double quotes, which means it is not working correctly
as a dynamic filter.  This fixes the quotes around the filter name, and also
updates the docblocks for the other 3 similar filters for better conformance to
the documentation standards.

a1ec867b61 REST API: Fix incorrect capability check on term create.
Change the capability check used in `WP_REST_Terms_Controller` when creating a new term is attempted, from `manage_terms` to `edit_terms`. This matches the behavior within the WordPress admin. See #35614.

a985a4d126 REST API: Always fire the rest_insert_* actions after the related object is updated or inserted.
Brings consistency to the `rest_insert_*` actions. Also includes some shuffling and clean-up as well including:
- Ensure we are passing the most current `$post` and `$user` objects to the `update_additional_fields_for_object()` callbacks.
- Changes the function signature of `handle_status_param()` in the Comments controller to accept just the comment_id as the 2nd parameter, instead of a full WP_Comment object. Only the comment_id is needed in the method, this avoids having to include another `get_comment()` call. 
- Renames a variable in the `create_item()` method of the Posts controller from `$post` -> `$prepared_post` to be more explicit.
- Minor fixes/clarifications to the rest_insert_* hook docs
