Switch Unicode Escaping to a VSCode-like system (#19990)
This PR rewrites the invisible unicode detection algorithm to more
closely match that of the Monaco editor on the system. It provides a
technique for detecting ambiguous characters and relaxes the detection
of combining marks.

Control characters are in addition detected as invisible in this
implementation whereas they are not on monaco but this is related to
font issues.

Add more linters to improve code readability (#19989)
Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability

- nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length.
- unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions
- wastedassign - https://github.com/sanposhiho/wastedassign -  wastedassign finds wasted assignment statements.
- notlintlint -  Reports ill-formed or insufficient nolint directives
- stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent
  - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)

Detect truncated utf-8 characters at the end of content as still representing utf-8 (#19773)
Our character detection algorithm can potentially incorrectly detect utf-8 as iso-8859-x
if there is a truncated character at the end of the partially read file.

This PR changes the detection algorithm to truncated utf8 characters at the end of the
buffer.

Fix #19743

Don't treat BOM escape sequence as hidden character. (#18909)
* Don't treat BOM escape sequence as hidden character.

- BOM sequence is a common non-harmfull escape sequence, it shouldn't be
shown as hidden character.
- Follows GitHub's behavior.
- Resolves #18837

Fix panic in EscapeReader (#18820)
There is a potential panic due to a mistaken resetting of the length parameter when
multibyte characters go over a read boundary.

Add warning for BIDI characters in page renders and in diffs (#17562)
Fix #17514

Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.

There is a button which can be used to escape the content to show it.

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Ensure that the detected charset order is set in chardet test (#12574)
TestToUTF8WithFallback is the cause of recurrent spurious test failures
even despite code to set the detected charset order.

The reason why this happens is because the preferred detected charset order
is not being initialised for these tests.

This PR simply ensures that this is set at the start of each test and would
allow different tests to be written to allow differing orders.
