When `ftp_nlist()` receives an empty path, it checks the current working directory and may return `true`.
This affects:
* `WP_Filesystem_FTPext::exists()`
* `WP_Filesystem_ftpsockets::exists()`
As the purpose of the API is to provide a consistent interface for various filesystem implementations, this commit updates the affected methods to returns `false` when an empty path is provided, bringing consistency with the other filesystem abstraction classes, specifically `WP_Filesystem_Direct` and `WP_Filesystem_SSH2`.

This partially reverts [53860] and [53862], which refactored the `exists()` method to rely on `ftp_rawlist()` instead of `ftp_nlist()`.
[53860] makes a similar attempt to the ones made in [33648] and [34733] (which were also reverted in [35944]). Being compliant with the specifications while continuing to work without issue for all FTP servers continues seem impossible. These little ghosts are the ones we’re scared of the most.

While `WP_Filesystem_Base::size()` is documented to return `false` on failure, `ftp_size()` returns -1, and the method documentation was recently updated to reflect that.
This commit restores the previous `@return` tag and corrects the actual return value instead, to bring consistency with all the other `WP_Filesystem_*::size()` methods:
* `WP_Filesystem_Base::size()`
* `WP_Filesystem_Direct::size()`
* `WP_Filesystem_ftpsockets::size()`
* `WP_Filesystem_SSH2::size()`
{{{
@return int|false Size of the file in bytes on success, false on failure.
}}}
This better matches the purpose of the API to provide a consistent interface for various filesystem implementations.

* `WP_Filesystem_FTPext::exists()`
* `WP_Filesystem_FTPext::size()`
* `WP_Filesystem_ftpsockets::exists()`
The `::exists()` methods were previously using the FTP `NLST` command, which works for directories, but is not intended to be applied to a file. This only worked most of the time due to many FTP servers being permissive and allowing to execute `NLST` on files, which cannot be guaranteed and appears to not be the case in newer versions of Pure-FTPd (1.0.48 or later).
With a recent change in [53860], both methods were updated for compatibility with RFC 959:
* Both methods check if the path is a directory that can be changed into (and therefore exists).
* `WP_Filesystem_FTPext` uses `ftp_rawlist()` (FTP `LIST` command) to check for file existence.
* `WP_Filesystem_ftpsockets` uses file size to check for file existence.

WordPress FTP file checking was previously based upon `ftp_nlist()`. This function can be problematic at scale with a directory containing a large number of files. The same issue occurred using it with ftpsockets.
This changeset rewrites the FTP `exists()` functions to utilize a more efficient and stable check.

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

PHP used to allow both square brackets and curly braces to be used interchangeably for accessing array elements and string offsets. The curly bracket syntax is only allowed in a limited set of cases and can be confusing for people not used to it.
PHP 7.4 will deprecate the curly brace syntax for accessing array elements and string offsets and it is expected that support will be completely removed in PHP 8.0.

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.

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.

This change causes it to list the parent directories files, and assets that the node exists within the returned listing, this is a little more compatible than relying upon the FTP server to correctly filter the returned resultset to the specific file/node being requested.

`LIST` & `NLST` by default on some servers require the `-a` flag to view hidden files (ie. `.maintenance`)
Although we could simply pass the `-a` flag to `NLST`, opting to use `LIST` which we use elsewhere should mean less chance of server incompatibilities.

Both methods are using *nlist() which returns a list of files in a given directory or the file itself for a given file. If the result was an empty list we assumed that the file doesn't exists. This includes also cases where $file is actually an empty directory. To prevent this we now check if $file is a directory before returning the result of an empty list.
Other filesystem methods are using `file_exists()` which already checks whether a file or directory exists.
