* Support custom sanitization policy
Allowing the gitea administrator to configure sanitization policy allows
them to couple external renders and custom templates to support more
markup. In particular, the `pandoc` renderer allows generating KaTeX
annotations, wrapping them in `<span>` elements with class `math` and
either `inline` or `display` (depending on whether or not inline or
block mode was requested).
This iteration gives the administrator whitelisting powers; carefully
crafted regexes will thus let through only the desired attributes
necessary to support their custom markup.

fixes#7868
* make linter happy

* expose markup type to template
previously all markup had the .markdown class, which is incorrect,
as it applies markdown CSS & JS logic to CSV rendering
* fix build (missing `make css`)
* ignore quoted csv content for delimiter scoring
also fix html generation
* Check commit message hashes before making links
Previously, when formatting commit messages, anything
that looked like SHA1 hashes was turned into a link
using regex. This meant that certain phrases or numbers
such as `777777` or `deadbeef` could be recognized as a commit
even if the repository has no commit with those hashes.
This change will make it so that anything that looks
like a SHA1 hash using regex will then also be checked
to ensure that there is a commit in the repository
with that hash before making a link.

Since #6273 was merged, we now have access to proper context metas
always. Update SHA generated links to use these instead of urlPrefix.
Update tests as well.
Fixes#4536.
* Improve issue autolinks
Update autolinks to match what github does here:
Issue in same repo: #1
Issue in different repo: org/repo#1Fixes#6264
* Use setting.AppURL when parsing URL
Using setting.AppURL here is a more reliable way of parsing the current
URL and what other functions in this file seem to use.
* Make ComposeMetas always return a valid context
* Add per repository markdown renderers for better context
* Update for use of context metas
Now that we include the user and repo name inside context metas, update
various code and tests for this new logic
* Use stricter boundaries for auto-link detection
Currently autolinks use \W for boundary detection which creates many
situations of inserting links into places they don't belong (paths,
URLs, UUIDs, etc...)
This fixes that by replacing \W and only allowing these matches to touch
an open paren or bracket (matching what seems to be Github behavior) in
addition to whitespace and start of line. Similar for ending boundary as
well.
Fixes#6149
(and probably others)
* Update test
Replace incorrect test with a value that is a valid username, based on:
"Username should contain only alphanumeric, dash ('-'), underscore ('_')
and dot ('.') characters."
* Also allow for period at the end
Matching Github behavior
* Fix email regex to work properly with specificed boundaries
Create a specific capture group for email address and then use
FindStringSubmatchIndex to allow for non-matching patterns as
boundaries.
* Add Tests
Add tests for new behavior -- including tests for email addresses which
were absent before.
This improves the SHA1 link detection to not pick up extraneous
non-whitespace characters at the end of the URL. The '.' is a special
case handled in code itself because of missing regexp lookahead
support.

* Markdown: update and exted tests
Update and add tests for additionally enabled Markdown-extensions.
* Replace linkRegex with xurls library
Rather than maintaining a complicated regex to match URLs for
autolinking, gitea can use this existing go library that takes care of
the matching with very little code change to gitea itself. After
spending a while trying to find the perfect regex for all cases this library
still works better as it is more flexible than a single regex ever will be.
This will also fix the following issues: #5844#3095#3381
This passes all our current tests and I've added new ones mentioned in
those issues as well.
* Use xurls.StrictMatchingScheme instead of xurls.Strict
This is much faster and we only care about https? links to preserve
existing behavior.
The visitLinksForShortLinks feature would look inside of an <a> tag and
run shortLinkProcessorFull on any text, which attempts to create links
out of potential 'short links' like [[test]] [[link|example]] etc...
This makes no sense because you can't have nested links within an <a>
tag. Specifically, the html5 standard says <a> tags can't include
interactive content if they contain the href attribute:
http://w3c.github.io/html/single-page.html#the-a-element
And also defines an <a> element with a href attribute as interactive:
http://w3c.github.io/html/single-page.html#interactive-content
Therefore you can't really put a link inside of another link. In
practice none of this works anyways since browsers won't render it, it
would probably be broken if they tried, and it is causing a bug
(#4946). No current tests rely on this behavior either.
This removes the feature and also explicitly excludes the
current visitNodeForShortLinks from looking in <a> tags.
Modify the current linkRegex to require http|https which appears to be
the intended behavior based on the comments. Right now, it also matches
anything starting with www as well. Also add testing for linkRegex
