soupsieve is a heavy-weight dependency, and Tornado pulls it in by way
of markdown rendering; since we are only using it for a very simple
process, perform that manually.
Per CSS spec[^1]:

The type annotation for functools.partial uses unchecked Any for all
the function parameters (both early and late). returns.curry.partial
uses a mypy plugin to check the parameters safely.

Fixes#11767.
Previously multi-character emoji sequences weren't matched in the
emoji regex, so we'd convert the characters to separate images,
breaking the intended display.
This change allows us to match the full emoji sequence, and
therefore show the correct image.
This is later used for supporting RFC 6570 URI Template in place of the
URL format string that we were using for linkifiers.

Primary goal of library replacement is improving execution speed.
This commit should not affect the functionality of the system
or make any changes to it.
Previously, `QuerySet` does not support isinstance check since it is
defined to be generic in django-stubs. In a recent update, such check is
possible by using `QuerySetAny`, a non-generic alias of `QuerySet`.

The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break. Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.
It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
- Content-Type
- Content-Disposition
- Accept-Ranges
- Set-Cookie
- Cache-Control
- Expires
As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.
