FEATURE: Tag synonyms
This feature adds the ability to define synonyms for tags, and the ability to merge one tag into another while keeping it as a synonym. For example, tags named "js" and "java-script" can be synonyms of "javascript". When searching and creating topics using synonyms, they will be mapped to the base tag.

Along with this change is a new UI found on each tag's page (for example, `/tags/javascript`) where more information about the tag can be shown. It will list the synonyms, which categories it's restricted to (if any), and which tag groups it belongs to (if tag group names are public on the `/tags` page by enabling the "tags listed by group" setting). Staff users will be able to manage tags in this UI, merge tags, and add/remove synonyms.

Krzysztof Kotlarek 427d54b2b0 DEV: Upgrading Discourse to Zeitwerk (#8098)
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. 

We no longer need to use Rails "require_dependency" anywhere and instead can just use standard 
Ruby patterns to require files.

This is a far reaching change and we expect some followups here.

Sam Saffron 6428aa5b1f FIX: search indexer had various cases where it could fail
Previous to this fix is a post had the test www.test.com/abc it would fail
to index.

This also simplifies the rules to avoid full url parsing which can be
expensive

Gerhard Schlager 876c4f20b3 FIX: Remove duplicate Emoji names from blurb
The blurb contained the value of the alt and title attribute of Emojis. Both values are always the same.

Gerhard Schlager 71d19f6e1f FIX: Reduce mentions in blurbs to @username or @groupname
The link to the user profile or group is useless and the URL encoded username or group name looks awful for Unicode names

Also move `Search::INDEX_VERSION` to `SearchIndexer` which is where the
version is actually being used.

PERF: Improve quality of `PostSearchData#raw_data`. (#7275)
This commit fixes the follow quality issue with `PostSearchData#raw_data`:

1. URLs are being tokenized and links with similar href and characters
are being duplicated in the raw data.

`Post#cooked`:

```
<p><a href=\"https://meta.discourse.org/some.png\" class=\"onebox\" target=\"_blank\" rel=\"nofollow noopener\">https://meta.discourse.org/some.png</a></p>
```

`PostSearchData#raw_data` Before:

```
This is a test topic 0 Uncategorized https://meta.discourse.org/some.png discourse org/some png https://meta.discourse.org/some.png discourse org/some png
```

`PostSearchData#raw_data` After:

```
This is a test topic 0 Uncategorized https://meta.discourse.org/some.png meta discourse org
```

2. Ligthbox being included in search pollutes the
`PostSearchData#raw_data` unncessarily.

From 28 March 2018 to 28 March 2019, searches for the term `image` on
`meta.discourse.org` had a click through rate of 2.1%. Non-lightboxed images are not included in indexing for search yet we were indexing content within a lightbox. Also, search for terms like `image` was affected we were using `Pasted image` as the filename for
uploads that were pasted.

`Post#cooked`

```
<p>Let me see how I can fix this image<br>\n<div class=\"lightbox-wrapper\"><a class=\"lightbox\" href=\"https://meta.discourse.org/some.png\" title=\"some.png\" rel=\"nofollow noopener\"><img src=\"https://meta.discourse.org/some.png\" width=\"275\" height=\"299\"><div class=\"meta\">\n<svg class=\"fa d-icon d-icon-far-image svg-icon\" aria-hidden=\"true\"><use xlink:href=\"#far-image\"></use></svg><span class=\"filename\">some.png</span><span class=\"informations\">1750×2000</span><svg class=\"fa d-icon d-icon-discourse-expand svg-icon\" aria-hidden=\"true\"><use xlink:href=\"#discourse-expand\"></use></svg>\n</div></a></div></p>
```

In terms of indexing performance, we now have to parse the given HTML
through nokogiri twice. However performance is not a huge worry here since a string length of 194170 takes only 30ms
to scrub plus the indexing takes place in a background job.

Guo Xiang Tan d808f36fc4 FIX: Reindex post for search when post is moved to a different topic.
* This is causing certain posts to appear in searches incorrectly as `PostSearchData#raw_data` contains the outdated title, category name and tag names.

Daniel Hollas cee51672c9 FIX: Strip accents from search query
4481836 introduced accent stipping in search_indexer,
but we need to strip it from the query itself as well

TODO in search with diacritics:
 - Still need to fix excerpts on search page
 - need to support accent stripping in in_topic search
 - need to make sure that in:title works correctly
 - need to fix "word boldening" in titles

FEATURE: Mixed case tagging (#6454)
- By default, behaviour is not changed: tags are made lowercase upon creation and edit.

- If force_lowercase_tags is disabled, then mixed case tags are allowed.

- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.

- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.

- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.

- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.

Sam 5f64fd0a21 DEV: remove exec_sql and replace with mini_sql
Introduce new patterns for direct sql that are safe and fast.

MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API

- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder
