Append :!aNULL:!eNULL:!EXP to the cipher string settings,
instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
and later). Enables support for configuring the SUITEB* cipher
strings introduced in OpenSSL 1.0.2. PR 58213.

mod_ssl namespacing

Proposed by: kbrand

mod_ssl namespacing: Rename ssl_util_ssl.h macros from SSL_foo to MODSSL_foo.
For related discussion, see the dev@ thread starting at:
http://mail-archives.apache.org/mod_mbox/httpd-dev/201504.mbox/%3C20150415163613.GC15209%40fintan.stsp.name%3E

mod_ssl namespacing: Rename SSL_init_app_data2_idx, SSL_get_app_data2,
and SSL_set_app_data2 from SSL_* to modssl_*. Update references in
README.dsov.* files. Rename static variable SSL_app_data2_idx to just
app_data2_idx since the symbol is internal to ssl_util_ssl.c.

mod_ssl namespacing: SSL_read_PrivateKey -> modssl_read_privatekey

mod_ssl namespacing: SSL_smart_shutdown -> modssl_smart_shutdown

mod_ssl namespacing: SSL_X509_getBC -> modssl_X509_getBC

mod_ssl namespacing: Make SSL_ASN1_STRING_to_utf8 a static function inside
ssl_util_ssl.c (no callers outside this file). The new static function name
chosen is convert_asn1_to_utf8, based on the assumption that neither SSL_
nor ASN1_ are safe prefixes to use without potential future overlap.

mod_ssl namespacing: Rename SSL_X509_NAME_ENTRY_to_string to
modssl_X509_NAME_ENTRY_to_string.

mod_ssl namespacing: SSL_X509_NAME_to_string -> modssl_X509_NAME_to_string

mod_ssl namespacing: SSL_X509_getSAN -> modssl_X509_getSAN

mod_ssl namespacing: Make SSL_X509_getIDs a static function inside the
file ssl_util_ssl.c (no outside callers). Rename to just getIDs().

mod_ssl namespacing: SSL_X509_match_name -> modssl_X509_match_name

mod_ssl namespacing: SSL_X509_INFO_load_file -> modssl_X509_INFO_load_file

mod_ssl namespacing: Merge SSL_X509_INFO_load_path() into its only caller
ssl_init_proxy_certs() in ssl_engine_init.c. No functional change.
Review by: kbrand

mod_ssl namespacing: Move modssl_X509_INFO_load_file() into ssl_engine_init.c
and make it a static function called load_x509_info().

mod_ssl namespacing: Move SSL_CTX_use_certificate_chain() into ssl_engine_init.c
and make it a static function called use_certificate_chain().

mod_ssl namespacing: Rename SSL_SESSION_id2sz() to modssl_SSL_SESSION_id2sz().
