`get_term_by()` always returns a single term, even when more than one term
matches the query parameters. The new note warns developers to use
`get_terms()` when such ambiguity may result.

[37623] used the wrong parameter name (count=true instead of fields=count).
For greater flexibility and forward compatibility with other potential changes
to the return value of `get_terms()`, we now do a looser check: any non-array
value is excluded from the filter.

Use of the 'get_terms' filter was consolidated in [37572], with the
introduction of `WP_Term_Query`. At that time, the result of 'count=true'
queries began being filtered by 'get_terms'. This breaks existing 'get_terms'
callbacks, which often assume that the returned value will be an array or a
`WP_Error` object.

Prior to [37572], arguments passed to `get_terms()` were passed immediately
through `wp_parse_args()`, which made it possible to pass arguments as a
querystring (`hide_empty=0`) rather than an array
(`array( 'hide_empty' => false )`). [37572] moved default argument parsing
into `WP_Term_Query`, while assuming that arguments passed to `get_terms()`
would be formatted as an array.
To provide compatibility, we now parse all args passed to `get_terms()` into
an array before processing.

Since [37573], object relationship caches (`{$taxonomy}_relationships`)
contain term IDs rather than term objects. See #36814. As such, it's no longer
necessary to clear these caches when a term is updated; none of the data that's
changed on update (name, description, count, etc) is stored in the relationship
cache.

Previously, objects containing all data about a term were stored in each
object's term cache. Besides being wasteful, this approach caused invalidation
issues, as when a modified term count required a flush for all objects
belonging to the term.
Backward compatibility is maintained for plugins that continue to put object
data directly into the `{$taxonomy}_relationships` cache bucket.

[34529] introduced logic intended to prime the termmeta cache for certain
values of the `fields` parameter. There were a few bugs:
* The `all_with_object_id` param was misspelled.
* `term_id` was used instead of `ids`.
* The values being passed to `update_termmeta_cache()` in the case where `fields=ids` was not correct.
All of these would result in a failure to pre-fetch termmeta in some cases.

The codex says that taxonomy names "should only contain lowercase letters and the underscore character", but that's not enforced. It's too late to enforce it, since some plugins haven't been following it and the official phpdoc doesn't mention this restriction.

When querying for terms in hierarchical taxonomies, `get_terms()` initially
queries for all matching terms, and then trims the located results based on the
`$number` and `$offset` arguments passed to the function. See #8832. However,
a flaw in the original logic meant that results were failing to be trimmed
properly in cases where `$offset` exceeds the total number of matching terms;
in these cases, we should force an empty array.

`get_terms()` has historically required that a taxonomy be specified when
querying terms. This requirement is related to the fact that terms could
formerly be shared between taxonomies, making `$taxonomies` critical for
disambiguation. Since terms can no longer be shared as of 4.4, it'
s desirable to be able to query for terms regardless of what taxonomy they're in.
Because it's now optional to pass taxonomies, it's no longer necessary to have
`$taxonomies` as the first (and required) parameter for `get_terms()`. The new
function signature is `get_terms( $args )`, where 'taxonomy' can (optionally) be
passed as part of the `$args` array. This syntax is more consistent with
functions like `get_users()` and `get_posts()`.
We've maintained backward compatibility by always giving precedence to the old
argument format. If a second parameter is detected, or if it's detected that
the first parameter is a list of taxonomy names rather than an `$args` array,
`get_terms()` will parse the function arguments in the legacy fashion.

The `$orderby` parameter of `get_terms()` now accepts the following values,
related to term meta:
* 'meta_value'
* 'meta_value_num'
* the value of the `$meta_key` parameter
* any key from the `$meta_query` array
This brings order-by-meta support for terms in line with post, comment, and
user queries.
As a byproduct of these improvements, `$meta_key` and `$meta_value` parameters
have been introduced to `get_terms()`. They interact with `$meta_query` in the
same way as in `WP_Query` and other query classes.

[32353] changed the way the 'name' param in `get_terms()` is sanitized, by
running it through `sanitize_term_field( 'name' )` before performing the SQL
query. An unintentional side effect of this change was that the string is
double-escaped: once by `wp_filter_kses()`, and once by `esc_sql()`. The
double-escaping was causing 'name' queries to fail when the param contained
apostrophes or other escaped characters.

[34999] modified the cache strategy for terms in the context of
`wp_get_object_terms()`. As part of these changes, the `object_id` property of
term objects had to be unset before being cached. To avoid modifying passed-by-
reference terms, `update_term_cache()` attempted to make a copy of the terms
passed to the function; however, it failed to use the `clone` keyword, and thus
only created a reference instead of a copy.

[35333] implemented `public=false` for taxonomies. The implementation prevented
non-public taxonomies from having their archives accessed via query_var during
a normal request. But it didn't prevent non-public taxonomies from registering
their query vars in the `$wp_taxonomies` global. The latter implementation
details causes problems specifically when a taxonomy is registered with
`query_var=true`; for public taxonomies, `register_taxonomy()` translates this
into a query_var equivalent to the taxonomy name, but in the case of non-public
taxonomies, the query_var was set to the boolean itself. The boolean then
causes problems when using non-strict comparison to filter taxonomy objects by
query_var, as when using `get_taxonomies()`.
This changeset addresses the issue by forcing the query_var property of
non-public taxonomies to `false`.
