Fixes the following security issues:
- CVE-2021-40346: An integer overflow exists in HAProxy 2.0 through 2.5 in
the htx_add_header() can be exploited to perform an HTTP request smuggling
attack, allowing an attacker to bypass all configured http-request HAProxy
ACLs and possibly other ACLs.

Fixes the following security issues:
- CVE-2021-39240: An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3
before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme
and path portions of a URI have the expected characters. For example, the
authority field (as observed on a target HTTP/2 server) might differ from
what the routing rules were intended to achieve.
- CVE-2021-39241: An issue was discovered in HAProxy 2.0 before 2.0.24, 2.2
before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. An HTTP method
name may contain a space followed by the name of a protected resource. It
is possible that a server would interpret this as a request for that
protected resource, such as in the "GET /admin? HTTP/1.1 /static/images
HTTP/1.1" example.
- CVE-2021-39242: An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3
before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an
attacker-controlled HTTP Host header, because a mismatch between Host and
authority is mishandled.

- Fix CVE-2020-11100: In hpack_dht_insert in hpack-tbl.c in the HPACK
decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can
write arbitrary bytes around a certain location on the heap via a
crafted HTTP/2 request, possibly causing remote code execution.
- Update indentation of hash file (two spaces)
