Subject: [PATCH] ftp,imap,pop3,smtp: reject STARTTLS server response
pipelining
If a server pipelines future responses within the STARTTLS response, the
former are preserved in the pingpong cache across TLS negotiation and
used as responses to the encrypted commands.
This fix detects pipelined STARTTLS responses and rejects them with an
error.

Subject: [PATCH] openldap: replace ldap_ prefix on private functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since openldap itself uses that prefix and with OpenĹDAP 2.5.4 (at
least) there's a symbol collision because of that.
The private functions now use the 'oldap_' prefix where it previously
used 'ldap_'.
Reported-by: 3eka on github
Fixes #7004
Closes #7005

Subject: [PATCH 2/4] runtests: do CRLF replacements per section only
The `crlf="yes"` attribute and "hyper mode" are now only applied on a
subset of dedicated sections: data, datacheck, stdout and protocol.
Updated test 2500 accordingly.
Also made test1 use crlf="yes" for <protocol>, mostly because it is
often used as a template test case. Going forward, using this attribute
we should be able to write test cases using linefeeds only and avoid
mixed line ending encodings.
Follow-up to ca15b7512e8d11
Fixes #10009
Closes #10010
