47c44355b5 SSL: use of SSL_MODE_NO_AUTO_CHAIN.
The SSL_MODE_NO_AUTO_CHAIN mode prevents OpenSSL from automatically
building a certificate chain on the fly if there is no certificate chain
explicitly provided.  Before this change, certificates provided via the
ssl_client_certificate and ssl_trusted_certificate directives were
used by OpenSSL to automatically build certificate chains, resulting
in unexpected (and in some cases unneeded) chains being sent to clients.

a20c6d202e SSL: avoid SSL_CTX_set_tmp_rsa_callback() call with LibreSSL.
LibreSSL removed support for export ciphers and a call to
SSL_CTX_set_tmp_rsa_callback() results in an error left in the error
queue.  This caused alerts "ignoring stale global SSL error (...called
a function you should not call) while SSL handshaking" on a first connection
in each worker process.

b0d8ff55a1 SSL: clear protocol options.
LibreSSL 2.1.1+ started to set SSL_OP_NO_SSLv3 option by default on
new contexts.  This makes sure to clear it to make it possible to use SSLv3
with LibreSSL if enabled in nginx config.

cc569b9252 Core: added cyclic memory buffer support for error_log.
Example of usage:

  error_log memory:16m debug;

This allows to configure debug logging with minimum impact on performance.
It's especially useful when rare crashes are experienced under high load.

The log can be extracted from a coredump using the following gdb script:

  set $log = ngx_cycle->log

  while $log->writer != ngx_log_memory_writer
      set $log = $log->next
  end

  set $buf = (ngx_log_memory_buf_t *) $log->wdata
  dump binary memory debug_log.txt $buf->start $buf->end

c34368715f Thread pools: silence warning on process exit.
Work around pthread_cond_destroy() and pthread_mutex_destroy() returning
EBUSY.  A proper solution would be to ensure all threads are terminated.

afe1fcffaa Thread pools: fixed the waiting tasks accounting.
Behave like POSIX semaphores.  If N worker threads are waiting for tasks,
at least that number of tasks should be allowed to be put into the queue.

b89e3bc034 Configure: fixed type max value detection.
The code tried to use suffixes for "long" and "long long" types, but
it never worked as intended due to the bug in the shell code.  Also,
the max value for any 64-bit type other than "long long" on platforms
with 32-bit "long" would be incorrect if the bug was fixed.

So instead of fixing the bug in the shell code, always use the "int"
constant for 32-bit types, and "long long" constant for 64-bit types.

2f3fb935b4 Upstream keepalive: drop ready flag on EAGAIN from recv(MSG_PEEK).
Keeping the ready flag in this case might results in missing notification of
broken connection until nginx tried to use it again.

While there, stale comment about stale event was removed since this function
is also can be called directly.

ea881578a2 Refactored ngx_linux_sendfile_chain() even more.
The code that calls sendfile() was cut into a separate function.
This simplifies EINTR processing, yet is needed for the following
changes that add threads support.

14a93c5a15 Upstream: upstream argument in ngx_http_upstream_process_request().
In case of filter finalization, r->upstream might be changed during
the ngx_event_pipe() call.  Added an argument to preserve it while
calling the ngx_http_upstream_process_request() function.

2b032e8df6 Upstream: avoid duplicate finalization.
A request may be already finalized when ngx_http_upstream_finalize_request()
is called, due to filter finalization: after filter finalization upstream
can be finalized via ngx_http_upstream_cleanup(), either from
ngx_http_terminate_request(), or because a new request was initiated
to an upstream.  Then the upstream code will see an error returned from
the filter chain and will call the ngx_http_upstream_finalize_request()
function again.

To prevent corruption of various upstream data in this situation, make sure
to do nothing but merely call ngx_http_finalize_request().

46a2236f22 SSL: reset ready flag if recv(MSG_PEEK) found no bytes in socket.
Previously, connection hung after calling ngx_http_ssl_handshake() with
rev->ready set and no bytes in socket to read.  It's possible in at least the
following cases:

 - when processing a connection with expired TCP_DEFER_ACCEPT on Linux
 - after parsing PROXY protocol header if it arrived in a separate TCP packet
