This is a final pass to fix PHP compatibiilty issues in the codebase with code changes or adding `phpcs:ignore` comments.
With this change, all PHP compatibility warnings and errors without specific tickets have been addressed (see #49810 and #41750).

Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.
While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.
This changeset implements the following logic (only applied if WordPress is installed in the root directory):
* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.
Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.
New functions and hooks:
* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.

This change introduces a new Composer script, `compat` that will scan the codebase for (detectable) potential PHP compatibility issues using the `PHP_CodeSniffer` and a custom ruleset based off of the `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).
The command will be run as a separate job within each Travis build. While many compatibility issues and false positives have already been corrected in this commit and other Trac tickets, there are still some remaining. For that reason, the job is allowed to fail while the remainder of the potential compatibility issues are investigated and addressed. After those are resolved, the job should be set as required to pass to help prevent new compatibility issues from being introduced.

The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), JSON extension related polyfills and backwards compatibility code can now be removed.
This change removes code that supported JSON related functionality on older versions of PHP. This includes (but is not limited to) checks that `json_last_error()` exists, checking and setting the `JSON_UNESCAPED_SLASHES` and `JSON_PRETTY_PRINT` constants if not previously defined, and deprecating the `_wp_json_prepare_data()` function (which was 100% workaround code).

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.

Prior to this change, each `wp_die()` handler had their own logic for how to parse arguments, causing inconsistencies and even breakage because the arguments possible to pass to `wp_die()` depended on the request context. Passing a `WP_Error` as `$message` for example used to be only support by the default handler, but not the AJAX and XML-RPC handlers.
With the fatal error protection, plus the new `wp_die()` handlers related to that, improving this support and compatibility has become more significant. Therefore this changeset introduces a private `_wp_die_process_input()` function that handles all function parameters consistently.

WordPress has historically often used code like `preg_split( '/[\s,]+/', $var )` to parse a string of comma-separated values into an array. However, this approach was causing an empty string to not be parsed into an empty array as expected, but rather into an array with the empty string as its sole element.
This was among other areas causing problems in the REST API where passing an empty request parameter could cause that request to fail because, instead of it being ignored, that parameter would be compared against the valid values for it, which typically do not include an empty string.

* If that URL is different from the default one that points to https://wordpress.org/support/update-php/ or its localized equivalent, a note indicates that the linked resource has not been provided by WordPress itself, and the default URL is still linked to as an additional resource.

The docs for `date_i18n()` and its filter now correctly state that the `$gmt` parameter is only taken into account if no timestamp is provided. Furthermore, a bug with that parameter is fixed, as it is now ensured that the timezone used with it is `UTC`.
Props Rarst.
