b1804afeaf Docs: Standardize on 'backward compatibility/compatible' nomenclature in core inline docs.
Also use 'back-compat' in some inline comments where backward compatibility is the subject and shorthand feels more natural.

Note: 'backwards compatibility/compatibile' can also be considered correct, though it's primary seen in regular use in British English.

a800cf654b Drop Open Sans in the admin in favor of system fonts.
Rejoice, for your admins will feel more native to your surrounding computing environment and likely load faster, especially when offline, as they no longer have to talk to The Google Overlord.

At the time of introduction in 3.8, there were not good system fonts common to all platforms at the time. In the years since, Windows, Android, OS X, iOS, Firefox OS, and various flavors of Linux have all gotten their own (good) system UI fonts.

There will definitely be visual bugs, mainly around alignment and spacing; these should be documented and reported on the ticket and fixed more atomically so that our current and future selves have a better understanding of what happened and why.

The style remains registered, as it is almost certainly in use by themes and plugins.

fe3b007fdd Docs: Remove inline @see tags from function, class, and method references in inline docs.
Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.

Note: Hook references are still linked via inline `@see` tags due to the unlikelihood of reliably matching for known hooks based on a RegEx pattern.

33cb1be012 Emoji: The :roll: smiley is now an emoji.
Unicode 8 added `U+1F644`, "Face with Rolling Eyes", which matches our `:roll:` smiley. Continuing our ever present quest to rid the world of legacy smilies, we now translate that smiley into its emoji form.

Sadly, `:mrgreen:` remains sorely under-represented in the Unicode standard, I'm inclined to think that we should buy a voting membership of the Unicode Consortium, in order to rectify that situation. (Personally, I'm hoping for a green skin tone modifier.)

3df07b17dd Media: Don't cache the results of wp_mkdir_p() in a persistent cache.
To improve the performance of `wp_upload_dir()` the result of `wp_mkdir_p()` was stored in a persistent cache, introduced in [36565]. But this becomes an issue when WordPress is scaled horizontally. You may end up caching a value for a server where the directory doesn't exist which will prevent further uploads on other servers because of the persistent cache.
The fix is to use a non-persistent cache.

1972aa2a2a Add grunt prerelease task
An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.

da5b3a55c4 Improve the performance of wp_upload_dir():
- Cache the output in non-persistent cache.
- Cache the result from `wp_mkdir_p()` in persistent cache (when present).
- Introduce `wp_get_upload_dir()` for use when not uploading files. It is equivalent to `wp_upload_dir()` but does not check for the existence or create the upload directory.
- Change tests to use the non-cached `_wp_upload_dir()`. They change options on the fly (should never be used in production) to simulate different environments.
- Introduce `_upload_dir_no_subdir()` and `_upload_dir_https()` to facilitate testing. These use the proper `upload_dir` filter to simulate different environments.

4bac3c3f14 REST API: Add JsonSerializable compatibility to wp_json_encode
Following on from r34845, the JsonSerializable shim needs support
on the encoding side too. _wp_json_prepare_data handles this when
we've loaded the shim.

9926983b66 Revert [34778], continue using _site_option() for the current network.
The `_network_option()` parameter order will be changing to accept `$network_id` first. The `_site_option()` functions will remain in use throughout core as our way of retrieving a network option for the current network.

226bb29ff0 Move wp_installing() to load.php.
Various functions in load.php need to check whether WP is in installation mode.
Let's let them.

0e7c1d3b14 Use wp_installing() instead of WP_INSTALLING constant.
The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.

A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available.  However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.

The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.
