For a number of years, most of the WordPress error messages have been prefixed with "Error:". However, these messages appear in a context where it's already clear an error occurred. Whether it's an error, a warning, or any other classification, that's not so relevant for users. The content of the message is the relevant part. The "Error:" prefix doesn't add great value while it does add unnecessary complexity for the message readability.
Also, revises some of these messages to improve clarity and removes HTML from translatable strings.

Previously, the `@` operator was used to prevent possible warnings emitted by `parse_url()` in PHP < 5.3.3 when URL parsing failed.
Now that the minimum version of PHP required by WordPress is 5.6.20, this is no longer needed.

This is the first step to bring support for custom comment types into WordPress.
Add a scheduled upgrade routine to update the type value for existing comments, in batches of 100 at a time.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

Previously, the direct SQL query used to identify trackbacks in
`do_all_pings()` performed poorly, due to an unindexed query against the
`to_ping` column. We improve performance in two ways. First, we switch
to using a postmeta flag for posts that require trackbacks to be sent;
queries joining against the postmeta table that check only the `meta_key`
are generally quite fast. Second, we switch to the use of `WP_Query`,
making the query cacheable and filterable using standard methods.

Removing the direct SQL query in `do_all_pings()` improves filterability.
As part of this change, the signature of `do_enclose()` is changed so that
a null `$content` parameter can be passed, with the `$content` then inferred
from the `$post` passed in the second parameter. In addition, the second
parameter was modified so that a post ID or a `WP_Post` object can be
provided. These changes make it possible to trigger enclosure checks with
a post ID alone (as in `do_all_pings()`) and also brings the function
signature in line with `do_trackbacks()` and `pingback()`.

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.

Use of `date()` in core depends on PHP timezone set to UTC and not changed by third party code (which cannot be guaranteed).
`gmdate()` is functionally equivalent, but is not affected by PHP timezone setting: it's always UTC, which is the exact behavior the core needs.

The "Your comment is awaiting moderation." message relied upon the comment author cookie being set. However, since it's now possible to opt-out of that cookie, submitting a comment won't show the comment preview when the comment is placed in moderation.
To avoid this issue, we now include a hash in the redirect URL, allowing the site to identify that a preview of the moderated comment should be displayed.
