CMakeLists.txt: use canonical GNUInstallDirs variable for docdir

We use the GNUInstallDir variables for the rest of the build system
locations, so let's use CMAKE_INSTALL_DOCDIR too to allow customisation
downstream.

(In Gentoo, we set it to the exact package version including downstream-only
revisions.)

Update Stubby to always send the `dot` ALPN when using DoT
 (commit: a5a1256)

Update stub.c

Fix for issue mentioned below:
Scenario: 4 UDP steams corresponding to 4 IP's configured.
Outbound query is always sent to 1st IP in the list unless there is a timeout.
If there is a timeout, the next outbound query is sent to the 2nd IP in the list.
If the 1st IP still times out then the next 2n queries (this increases in powers of 2) go to the 2nd IP.
If the 2nd IP times out at any point, then queries are sent to the 3rd IP (following the same algorithm of 2n queries before reverting to the 2nd IP)

Observation: Even if there is no timeout on 2nd IP, some queries are still sent to 3rd IP.
From code: The stream is switched whenever there is a timeout. If 10 messages were sent to first IP and they all timeout , the stream is switched 10 times in the current code.   
Suggestion: Switch stream only on the first timeout on a stream or ignore when the timeout occurs on a stream which is not the current_udp stream.

Increase CMake required version 3.5 -> 3.20

Commit 777e0b245c510e273e5ba917939a21778cb060f2 introduced cmake_path
which has been added to Cmake in 3.20 onlyi [1], so this should only make
the error message more explicit.
