from trunk resp. 917044 from 2.2.x:

New releases of OpenSSL will only allow secure renegotiation by
default.  Add an "SSLInsecureRenegotiation" directive to enable
renegotiation against unpatched clients, to ease transition.

Further mitigation for the TLS renegotation attack, CVE-2009-3555:

* modules/ssl/ssl_engine_kernel.c (has_buffered_data): New function.
  (ssl_hook_Access): Forcibly disable keepalive for the connection if
  there is any buffered data readable from the input filter stack.

* modules/ssl/ssl_engine_io.c (ssl_io_filter_input): Ensure that the
  BIO uses blocking operations when invoked outside direct control of
  the httpd filter stack.

Thanks to Hartmut Keil <Hartmut.Keil adnovum.ch> for proposing this
technique.

- removed obsolete include paths
- changed include paths to use internal vars so hat apr/apr-util builds outside source tree
- removed trailing tabs and spaces, other minor cosmetic changes

SECURITY: Partial fix for CVE-2009-3555:

Reject client-initiated renegotiations; this is sufficient to prevent
the attack for any configuration which does not require renegotiation
due to per-directory/per-location access control configuration.

Configuration with per-directory/per-location access control
requirements (such as "SSLVerifyClient require") are still vulnerable
to CVE-2009-3555 with this patch applied (if using OpenSSL != 0.9.8l).

* modules/ssl/ssl_private.h (SSLConnRec): Add reneg_state field.
  (ssl_callback_Info): Renamed from ssl_callback_LogTracingState.

* modules/ssl/ssl_engine_init.c (ssl_init_ctx_callbacks): Install
  the (renamed) info callback unconditionally.

* modules/ssl/ssl_engine_io.c (ssl_filter_ctx_t): Add config pointer
  to SSLConnRec.
  (bio_filter_out_write, bio_filter_in_read): Fail with
  APR_ECONNABORTED if the reneg state is set to RENEG_ABORT.

* modules/ssl/ssl_engine_kernel.c (log_tracing_state): Factored out
  of ssl_callback_LogTracingState.
  (ssl_callback_Info): New function.
