Add none-checks, rename variables (to avoid redefinition of
the same variable with different types error), add necessary
type annotations.
This is a part of #18777.

As a consequence:
• Bump minimum supported Python version to 3.8.
• Move Vagrant environment to Ubuntu 20.04, which has Python 3.8.
• Move CI frontend tests to Ubuntu 20.04.
• Move production build test to Ubuntu 20.04.
• Move 3.4 upgrade test to Ubuntu 20.04.

We had skipped these in #14693 so we could keep generating a friendly
error on Python 3.5, but we gave that up in #19801.

Changes in a529dc8 to raise exception for invalid file name
has removed support for passing full file paths.
This commit fixes it.
Thanks to Steve Howell (showell) for reporting this.
As a consequence:

• Move Vagrant environment to Debian 10, which has Python 3.7.
• Move CI frontend tests to Debian 10.
• Move production build test to Debian 10.

The development environment installs PostgreSQL from the OS, not PGDG,
so we should install the non-PGDG PGroonga package to match. This is
required on Debian 10 where postgresql-12-pgdg-pgroonga does not exist.

Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.
This requires modifying some tests to use valid uuids.
I have looked at maybe ~100 errors in the last week as part
of fixing the tooling, and it's quite common to want to just
see what the improved file would look like. Now I show the
desired output with line numbers.
I also try to encourage devs to scroll up, since newbies
often don't do that for some reason when confronted with
error output.
Finally, I add some color. I try to repeat myself without
color for certain things in case colors on certain
backgrounds are hard to read.
A fast way to test this is to just break up a long tag
into two lines.
`Press Enter to send` used to hide `Send` button, we remove that
behaviour.
We show the current state of `Enter` hotkey action via text below
`Send` button which can toggle behaviour on click.
Now we only tokenize the file once, and we pass
**validated** tokens to the pretty printer.
There are a few reasons for this:
* It obviously saves a lot of extra computation
just in terms of tokenization.
* It allows our validator to add fields
to the Token objects that help the pretty
printer.
I also removed/tweaked a lot of legacy tests for
pretty_print.py that were exercising bizarrely
formatted HTML that we now simply ban during the
validation phase.
This accomplishes a few things:
* lighten the load for the main validation loop
* defer indentation checks until we are sure the author
even knows how to match up tags
* add some info to the Token objects that we may soon
consume in our pretty-printer
We now complain about programmers who don't use
4-space indents in template files, rather than
letting the pretty printer fix them.
This is partly just to simplify the pretty printer
code (in future commits), but it also makes the
symptom more obvious to newbie developers. They
are probably just as able to react to the direct
error messages as they are able to figure out how
to read diffs from the pretty printer and grok
the --fix syntax. And once they learn the convention
and configure their editor, it should then be a
one time problem.
We now create tokens for whitespace and text, such that you
could rebuild the template file with "".join(token.s for
token in tokens).
I also fixed a few bugs related to not parsing
whitespace-control tokens.
We no longer ignore template variables, although we could do
a lot better at validating them.
The most immediate use case for the more thorough parser is
to simplify the pretty printer, but it should also make it
less likely for us to skip over new template constructs
(i.e. the tool will fail hard rather than acting strange).
Note that this speeds up the tool by almost 3x, which may be
slightly surprising considering we are building more tokens.
The reason is that we are now munching efficiently through
big chunks of whitespace and text at a time, rather than
checking each individual character to see if it starts one
of the N other token types.
The changes to the pretty_print module here are a bit ugly,
but they should mostly be made irrelevant in subsequent
commits.
