SSL_CTX_set_tmp_dh_callback though once generated as we leak
memory otherwise and freeing the structure up after use would be
hard to track and in fact is not needed at all as it is safe to
use the same parameters over and over again security wise (in
contrast to the keys itself) and code safe as the returned structure
is duplicated by OpenSSL anyway. Hence no modification happens
to our copy.

Transparency (RFC 6962) for httpd.
mod_ssl_ct requires OpenSSL 1.0.2 (in beta) and must be explicitly
enabled via configure.
Note that support/ctauditscts is purposefully not installed; it
does not properly function due to a dependency on a
certificate-transparency open source project tool which itself is
not sufficiently complete at this time.

This is enough to allow implementation of Certificate Transparency
outside of mod_ssl.

Putting the vhost-level elements last allows overriding global settings
(for the deprecated SSLRequire directive, the order is irrelevant,
all of them must be met, cf. ssl_engine_kernel.c:ssl_hook_Access).

- no longer send a warning-level unrecognized_name(112) alert
when no matching vhost is found (PR 56241)
- at startup, only issue warnings about IP/port conflicts and name-based
SSL vhosts when running with an OpenSSL without TLS extension support
(almost 5 years after SNI was added to 2.2.x, the
"[...] only work for clients with TLS server name indication support"
warning feels obsolete)

New SSLOCSPUseRequestNonce directive's manual and CHANGES.
Non functional code changes (modssl_ctx_t's field ocsp_use_request_nonce

in SSL_get_certificate for servers where the certificate hasn't
been sent.
Workaround by setting the ssl structure to client mode which
bypasses the faulty code in OpenSSL. Normally setting a server
ssl structure to client mode would cause problems later on:
but we are freeing the structure immediately without attempting
to use it.

and SSLCertificateKeyFile directives, and deprecate SSLCertificateChainFile
Splitting the patch into smaller pieces turned out to be infeasible,
unfortunately, due to the heavily intertwined code in ssl_engine_config.c,
ssl_engine_init.c and ssl_engine_pphrase.c, which all depends on the
modssl_pk_server_t data structure. For better comprehensibility,
a detailed listing of the changes follows:
ssl_private.h
- drop the X509 certs and EVP_PKEY keys arrays from modssl_pk_server_t
- use apr_array_header_t for cert_files and key_files
- drop tPublicCert from SSLModConfigRec
- drop the ssl_algo_t struct and the SSL_ALGO_* and SSL_AIDX_* constants
ssl_engine_config.c
- change to apr_array_header_t for SSLCertificate[Key]File
- drop ssl_cmd_check_aidx_max, i.e. allow an arbitrary number of certs
and keys (in theory; currently OpenSSL does not support more than
one cert/key per algorithm type)
- add deprecation warning for SSLCertificateChainFile
ssl_engine_init.c
- configure server certs/keys in ssl_init_server_certs (no longer via
ssl_pphrase_Handle in ssl_init_Module)
- in ssl_init_server_certs, read in certificates and keys with standard
OpenSSL API functions (SSL_CTX_use_*_file), and only fall back to
ssl_load_encrypted_pkey when encountering an encrypted private key
- drop ssl_server_import_cert, ssl_server_import_key, ssl_init_server_check,
and ssl_init_ctx_cleanup_server
- move the "problematic re-initialization" check to ssl_init_server_ctx
ssl_engine_pphrase.c
- use servername:port:index as the key identifier, instead of the
previously used servername:port:algorithm
- ssl_pphrase_Handle overhaul: remove all cert/public-key handling,
make it only load a single (encrypted) private key, and rename
to ssl_load_encrypted_pkey
- in the passphrase prompt message, show the private key file name
instead of the vhost id and the algorithm name
- do no longer supply the algorithm name as an argument to "exec"-type
passphrase prompting programs
ssl_util.c
- drop ssl_util_algotypeof, ssl_util_algotypestr, ssl_asn1_keystr,
and ssl_asn1_table_keyfmt
ssl_util_ssl.{c,h}
- drop SSL_read_X509
- constify the filename arg for SSL_read_PrivateKey

a pphrase_cb_arg_t struct instead, for passing stuff between
ssl_pphrase_Handle and ssl_pphrase_Handle_CB. Prefer struct
members instead of using additional local variables, to make
the data flow more transparent. (Doesn't "vastly simplify"
the code yet, but hopefully we'll get there when further
stripping down ssl_pphrase_Handle.)

- use cfgMergeArray, and reduce the size of the initial array
- move SSL_CONF_cmd calls from ssl_init_ctx_protocol to
ssl_init_server_ctx (so they are applied after ssl_init_server_certs)
- add APLOG_DEBUG-level logging for the SSL_CONF_cmd success case
- call SSL_CONF_CTX_free(cctx) when done in ssl_init_server_ctx

- was never documented, so very unlikely that it was ever used
- adds complexity without apparent benefit; PKCS#7 files can
be trivially converted to a file for use with SSLCertificateChainFile
(concatenated X509 CERTIFICATE chunks, openssl pkcs7 -print_certs...)
- only supports PKCS7 files with PEM encoding, i.e. relies on a
non-standardized PEM header (cf. RFC 2315 and draft-josefsson-pkix-textual)
- issues pointed out in http://mail-archives.apache.org/mod_mbox/httpd-dev/200607.mbox/%3C20060723093125.GA19423@redhat.com%3E
were never fully addressed (cf. r424707 and r424735)
- has never worked in vhost context due to a cfgMergeString
call missing from modssl_ctx_cfg_merge

* modules/ssl/ssl_engine_config.c (ssl_config_server_new): Default
sc->enabled to UNSET.
* modules/ssl/ssl_engine_init.c (ssl_init_Module): Only override
sc->enabled based on the protocol iff sc->enabled is UNSET; allows
"SSLEngine off" to override the Listen-based default.
