abcbee954f Coding Standards: Fix instances of WordPress.PHP.NoSilencedErrors.Discouraged.
Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

b57d185bb1 Formatting: Improve performance of wpautop() on large paragraphs.
Following [45585], older versions of PHP could segfault when attempting to autop paragraphs with 10,000+ characters.

Rather than having to negative lookahead for every character in the paragraph (which could run into recursion limits), we can quickly jump ahead to the next tag and start checking from there.

23de362563 Clean up stray <p> tags added by wpautop() inside block level tags.
`autop()` can sometimes get confused and not clean up stray `<p>` or `</p>` tags inside block level elements, which produces sub-optimal HTML. While browsers can generally handle it, there's no need to make things harder for them if we don't have to.

05fa2363ab Posts: Avoid the use of globals in get_the_content() and related functions.
This changeset introduces `$post` parameters to `get_the_content()` and
`wp_trim_excerpt()`. When a `$post` object is passed to one of these functions,
the functions will operate on the data from that object, rather than from the
post globals (`$authordata`, `$page`, etc). This ensures that the functions work
in a predictable manner when used outside of the regular post loop.

The global-mismatch problem is surfaced in cases where `get_the_excerpt()` is
called outside of the post loop, on posts that don't have a defined excerpt. In
these cases, the post globals - used to generate a fallback excerpt - may refer
to the incorrect object, resulting in PHP notices or other unpredictable
behavior. See #36934 for a related issue.

Changes of note:

- Includes the new Annotations API package.
- `wp-polyfill-ecmascript.js` is renamed to `wp-polyfill.js`.
- `strip_dynamic_blocks()` has been removed in favor of `excerpt_remove_blocks()`.
- The PHP block parser is now syncing from the `block-serialization-default-parser` package.
- `do_blocks()` uses the new parser.
- The `do_block` filter has been removed from `do_blocks()`, in favor of a `render_block` filter in `render_block()`.

Also, a little cleanup to `render_block()`. Always normalize `$block['attrs’]` to array in `’render_block’` filter.

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.

Fixes #44600.
