Partial backport of r1730351 from trunk.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x-openssl-1.1.0-compat@1755839 13f79535-47bb-0310-9956-ffa450edef68

- use SSL_peek instead of looping with
  has_buffered_data().

This fixes t/security/CVE-2009-3555.t where
has_buffered_data() doesn't help, because it
finds the buffered data and doesn't call
SSL_read(), so the reneg handshake isn't
triggered. SSL_peek() for 0 bytes seems to
reliably trigger the reneg in every case.

No more polling/sleeping. The code for the
OpenSSL 1.1.0 case is now again very close to
the pre 1.1.0 case.

Still need to run the full test suite with a
clean build.

- partial support for renegotiations.
  - Not a good design, need to poll until
    renegotitation has finished.
  - Loop criterion not right, if no client certs
    will be send.
  - Also doesn't work for EC or DH ciphers.
    Unclear how to fix with current 1.1.0
    API.

Unclear whether fdpass is common enough to justify a 'most' configuration,
but for the time being, assign it -something- for a build priority.

PR59815: rewrite per-directory + fcgi broken in 2.4.23

remove the query string from r->filename before calculating environment
(SCRIPT_FILENAME) in mod_proxy_fcgi.  Before PR59618, php-fpm would
see proxy:fcgi:// and do some of this same stripping.

Tested manually and verified httpd's mod_proxy_fcgi logs with various request types 
(with/without query string, long query strings, etc..). 
My only doubt was related to the '\0' terminator placed in the middle of the char array,
but after a chat with Eric on IRC I got a clear view of what happens (only the chars up
to the \0 terminator are placed in FCGI headers later on). 
Last but not the least, in the bugzilla ticket the original requestor tested the change
and stated that solved his problem. Looks good to me for backport!
