The old compatibility macro check no longer works,
because those are now actual functions, so an
ifndef is not the correct check.

- 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.

Netware: pull up ws2nlm imports from all (most)
proxy module makefiles to the main proxy makefile.

The individual module Makefiles overwrite
FILES_nlm_Ximports instead of appending.
Furthermore, now we know which modules need
this import so we can set it specifically
for those.

- don't check for SSLeay_version() in configure
  The function no longer exists in 1.1.0.
  It was replaced by OpenSSL_version().
- Switch between SSLeay_version(U) and
  OpenSSL_version() depending on version
  in modules/ssl/ssl_util_ssl.h.
- Use MODSSL_LIBRARY_DYNTEXT everywhere.

  - there are no header files in $(STDMOD)/http
  - $(STDMOD)/generators and $(STDMOD)/ssl

detected by Netware export/import awk
script.

We do not export proxy_module by putting it
into modules/proxy/NWGNUproxy explicitely,
because all accompanying proxy modules need
this symbol to access their config. So let
the awk script add proxy_module to the imp
file and then export it from mod_proxy and
import it to all other mod_proxy_xxx modules
via the imp file.

and instead use PROXY_DECLARE_OPTIONAL_HOOK which
is defined to be equal to APR_DECLARE_EXTERNAL_HOOK.

Correct explanation for the use of
PROXY_DECLARE_OPTIONAL_HOOK.

Use PROXY_DECLARE_OPTIONAL_HOOK for the correct
hooks.

Adjust build/make_nw_export.awk to match the new
PROXY_DECLARE_OPTIONAL_HOOK.

symbol import/export to differentiate between
hooks which call APR_HOOK_LINK() in the C
files and those who don't by marking them
in the header file.

in case when APR_HAVE_SYS_UN_H is not defined.
Just returns APR_ENOTIMPL.

This helps symbol export/import handling on
Netware and also seems to be more correct,
because mod_proxy.h contains ap_proxy_connect_uds()
unconditionally.
