8fd8c32ccf Modules compatibility: compatibility with NGX_HTTP_SSL.
With this change it is now possible to load modules compiled without
the "--with-http_ssl_module" configure option into nginx binary compiled
with it, and vice versa (if a module doesn't use ssl-specific functions),
assuming both use the "--with-compat" option.

0a961a0917 Modules compatibility: removed unneeded IPV6_V6ONLY checks.
The IPV6_V6ONLY macro is now checked only while parsing appropriate flag
and when using the macro.

The ipv6only field in listen structures is always initialized to 1,
even if not supported on a given platform.  This is expected to prevent
a module compiled without IPV6_V6ONLY from accidentally creating dual
sockets if loaded into main binary with proper IPV6_V6ONLY support.

ee37ff613f The HTTP/2 implementation (RFC 7240, 7241).
The SPDY support is removed, as it's incompatible with the new module.

50ff8b3c3a Core: idle connections now closed only once on exiting.
Iterating through all connections takes a lot of CPU time, especially
with large number of worker connections configured.  As a result
nginx processes used to consume CPU time during graceful shutdown.
To mitigate this we now only do a full scan for idle connections when
shutdown signal is received.

Transitions of connections to idle ones are now expected to be
avoided if the ngx_exiting flag is set.  The upstream keepalive module
was modified to follow this.

f7f1607bf2 The "reuseport" option of the "listen" directive.
When configured, an individual listen socket on a given address is
created for each worker process.  This allows to reduce in-kernel lock
contention on configurations with high accept rates, resulting in better
performance.  As of now it works on Linux and DragonFly BSD.

Note that on Linux incoming connection requests are currently tied up
to a specific listen socket, and if some sockets are closed, connection
requests will be reset, see https://lwn.net/Articles/542629/.  With
nginx, this may happen if the number of worker processes is reduced.
There is no such problem on DragonFly BSD.

Based on previous work by Sepherosa Ziehau and Yingqi Lu.

83ba5ed2ec Renamed NGX_THREADS to NGX_OLD_THREADS because of deprecation.
It's mostly dead code and the original idea of worker threads has been rejected.

2b8d6ad805 Refactored sendfile() AIO preload.
This reduces layering violation and simplifies the logic of AIO preread, since
it's now triggered by the send chain function itself without falling back to
the copy filter.  The context of AIO operation is now stored per file buffer,
which makes it possible to properly handle cases when multiple buffers come
from different locations, each with its own configuration.

0b5f329784 Added server-side support for PROXY protocol v1 (ticket #355).
Client address specified in the PROXY protocol header is now
saved in the $proxy_protocol_addr variable and can be used in
the realip module.

This is currently not implemented for mail.

8c01a95d98 SPDY: body filter was replaced by c->send_chain() function.
It allows to use ngx_http_write_filter() and all its rate limiting logic.

9a72030c25 Allowed up to two EBUSY errors from sendfile().
Fallback to synchronous sendfile() now only done on 3rd EBUSY without
any progress in a row.  Not falling back is believed to be better
in case of occasional EBUSY, though protection is still needed to
make sure there will be no infinite loop.

a32d3f8b6b Removed c->single_connection flag.
The c->single_connection was intended to be used as lock mechanism
to serialize modifications of request object from several threads
working with client and upstream connections.  The flag is redundant
since threads in nginx have never been used that way.

deaf22d220 Core: ipv6only is now on by default.
There is a general consensus that this change results in better
consistency between different operating systems and differently
tuned operating systems.

Note: this changes the width and meaning of the ipv6only field
of the ngx_listening_t structure.  3rd party modules that create
their own listening sockets might need fixing.
