Make (most) example snippets use the example.com domain instead of the
random ones picked and used before. Some of those were probably
legitimate sites and some not. example.com is designed for this purpose.
Now sorted into categories and organized in the same style we do the
TODO document. It will make each issue linked properly on the
https://curl.haxx.se/docs/knownbugs.html web page.
The sections should make it easier to find issues and issues related to
areas of the reader's specific interest.
Due to their age (we don't fully know if they actually remain) and lack
of detail - very few people will bother to find out what they're about
or work on them. If people truly still suffer from any of these, I
assume they will be reported again and then we'll deal with them.

It turns out the google GFE HTTP/2 servers send a PING frame immediately
after a stream ends and its last DATA has been received by curl. So if
we don't drain that from the socket, it makes the socket readable in
subsequent checks and libcurl then (wrongly) assumes the connection is
dead when trying to reuse the connection.

Although this should never happen due to the relationship between the
'mech' and 'resp' variables, and the way they are allocated together,
it does cause problems for code analysis tools:
V595 The 'mech' pointer was utilized before it was verified against
nullptr. Check lines: 376, 381. curl_sasl.c 376

This wouldn't cause a problem because of the way the function is called,
but prior to this change, we were processing the challenge message when
the credentials were NULL rather than when the challenge message was
populated.
This also brings this part of the Kerberos 5 code in line with the
Negotiate code.
Although mutual authentication is currently turned off and can only be
enabled by changing libcurl source code, authentication using Kerberos
5 has been broken since commit 79543caf90 in this use case.
