It is sometimes desirable to support shorter site names than 4 characters, therefore that restriction should be removed. It is still possible to manually enforce it by using the `wpmu_validate_blog_signup` filter.
As a result of this change, another `is_super_admin()` call gets removed which affects the ongoing efforts of working on a network-wide role system.

Prior to [38677], `get_term_by()` would always return false if
an empty string were passed as the queried 'name' or 'slug'. The
refactor to use `get_terms()` broke this behavior; inappropriately
imprecise `empty()` checks caused the 'name' or 'slug' clause to be
discarded altogether when fetching terms, resulting in an incorrect
term being returned from the function.
We fix the regression by special-casing truly empty values passed
to `get_term_by()`, and ensuring that `WP_Term_Query` is properly
able to handle `0` and `'0'` term queries.

The time chosen for `test_empty_post_date_gmt_shimmed_using_post_date` falls within US daylight savings time. This may cause the test to fail depending on whether the current locale has DST.
The fix is to specify a numeric `gmt_offset` rather than a `timezone_string`.

Historically, it has been possible to call `get_term_by()` within
a 'get_terms' filter callback. Since `get_term_by()` was refactored
to use `get_terms()` internally [38677], callbacks of this nature
have resulted in infinite loops.
As a workaround, we introduce a 'suppress_filter' option to `get_terms()`,
and use it when calling the function from within `get_term_by()`.

This change moves to specifying the PHPUnit version for all PHP versions, and fixes an issue where the Composer global bin directory is not at `~/.composer/vendor/bin` on the boxes that are used for HHVM builds.

Overriding pluggable functions in the test suite is asking for trouble in the future. In addition, it means the test suite can't be guaranteed to behave the same as core.
This instead introduces a `send_auth_cookies` filter which can be hooked in during the test suite to prevent these functions from attempting to send cookie headers to the client.

The site's current timezone offset is an important piece of information for any REST API client that needs to manipulate dates. It has not been previously available.
Expose both the `gmt_offset` (the site's current offset from UTC in hours) and `timezone_string` (which also provides information about daylight savings time) via the "site info" endpoint (the base `/wp-json` response).
Also update the `wp-api-generated.js` fixture file with the changes to the default API responses.

This commit adds some missing test cases for combinations of `orderby` and other parameters (`post_parent__in` and `post_name__in`).
Followup to [40056] for `orderby` and `post__in`.
The interaction of these parameters is perhaps counterintuitive because `orderby` does not affect the returned results. This is overall probably the best design, and it's now better tested and documented.

Terms with duplicate names are not allowed at the same level of a
taxonomy hierarchy. The name lookup introduced in [34809] did not
properly account for the 'parent' parameter, with the result that
the duplicate-name restriction was tighter than intended (terms
with duplicate names could not be created at different levels of
a single hierarchy).

`wp_insert_term()` does not allow for terms with the same name to exist
at the same hierarchy level, unless the second term has a unique slug.
When this logic was refactored in [31792] and [34809], a bug was
introduced whereby it was possible to bypass the no-same-named-sibling
check in cases where the first term had a non-auto-generated slug
(ie, where the name was 'Foo' but the slug something other than 'foo',
such that the second term would get the non-matching slug 'foo').
This changeset fixes this issue by ensuring that the duplicate name
check runs both in cases where there's an actual slug clash *and* in
cases where no explicit `slug` has been provided to `wp_insert_term()`.
The result is a more reliable error condition:
`wp_insert_term( 'Foo' ... )` will always fail if there's a sibling
'Foo', regardless of the sibling's slug.
