Hi,

based on some debugging issues it would be really helpful to see after
[<pid>] also the [<tid>] in KRB5_TRACE output. As far as I can see it is
printed in krb5int_trace(). Unfortunately, there is no portable (POSIX)
way to retrieve to retrieve it. Luckily, I have extended some code in
Tomcat Native recently to cover this on several platforms [1]. Code for
even more BSDs can be found here [2].

I can easily test a PR on RHEL7, FreeBSD 12 and HP-UX 11.31
