Krzysztof Kotlarek c32bd8ae48 FEATURE: Remove attachments and truncate raw field for incoming emails (#8253)
Adds the settings: 

raw_email_max_length, raw_rejected_email_max_length, delete_rejected_email_after_days. 

These settings control retention of the "raw" emails logs.

raw_email_max_length ensures that if we get incoming email that is huge we will truncate it removing uploads from the raw log.

raw_rejected_email_max_length introduces an even more aggressive truncation for rejected incoming mail. 

delete_rejected_email_after_days controls how many days we will keep rejected emails for (default 90)

Sam Saffron 5aaf7e3316 FIX: during concurrent emails generation renderer should not be reused
Our instance used for template rendering needs a lock to ensure there is
no race condition where rendering happens on 2 threads at the same time.

This can lead to local poisoning which can cause unexpected results in
emails

Sam Saffron 71ea4ad7fc PERF: reuse renderer when rendering email templates
Previous to this fix we were leaking methods on the internal action view
template class per render.

This caused email generation to be very low and a steady memory leak in the
application in sidekiq when sending out emails

The behavior change is new to Rails 6 so this fix does not need to be
backported into stable.

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 d05b724c4e FIX: correct race condition loading library
In some very rare cases CssParser could be loaded but CssParser::Parser not
this ensures we check for the actual constant we plan to call for concurrent
digest generations

Neil Lalonde 9656a21fdb
FEATURE: customization of html emails (#7934)
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.

Customizations can be added and edited in Admin > Customize > Email Style.

Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.

As part of this work, RTL locales are now rendered correctly for all emails.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

Sam Saffron 1be01f8dd4 DEV: Add support for Rails 6
Minor fixes to add Rails 6 support to Discourse, we now will boot
with RAILS_MASTER=1, all specs pass

Only one tiny deprecation left

Largest change was the way ActiveModel:Errors changed interface a
bit but there is a simple backwards compat way of working it

Sam Saffron 0a5a6dfded DEV: stop mutating inputs as a side effect
We had quite a few cases in core where inputs are being mutated as a side
effect of calling a method.

This handles all the cases where specs caught this.

Mutating inputs makes code harder to reason about. Eg:

```
frog = "frog"
jump(frog)
puts frog
"fly" # ?????
```

This commit is part of a followup commit that adds # frozen_string_literal
to all our specs.

David Taylor a9d5ffbe3d FIX: Prevent critical emails bypassing disable, and improve email test logic
- The test_email job is removed, because it was always being run synchronously (not in sidekiq)
- 34b29f62 added a bypass for critical emails, to match the spec. This removes the bypass, and removes the spec.
- This adapts the specs for 72ffabf6, so that they check for emails being sent
- This reimplements c2797921, allowing test emails to be sent even when emails are disabled

David Taylor 3f9e7eb326 FIX: Respect the disable_emails=non-staff site setting correctly
This reverts commit c279792130.

This commit inadvertently removed all of the non-staff email logic, rather than just for the 'test email' button.

Guo Xiang Tan 34b29f62db DEV: Remove the use of stubs and mocks in `Jobs::UserEmail` tests.
We can only be sure that an email is sent when we get a mailer in
`ActionMailer::Deliveries`. A couple of tests were actually incorrect
because it didn't flow through our email sender where there are more
conditions in determining whether an email is sent or not.
