It turned out they need additional processing to work.

Since PHP 7, a zend_signal_startup() call is required if the interpreter
was built with ZEND_SIGNALS defined; such a call was added in 3fd76e4ce70a.
However, the zend_signal_startup() export is missing from the PHP library;
as the result, dlopen() fails with the 'Undefined symbol "zend_signal_startup"'
error while loading the PHP module.
Meanwhile, if PHP is built without ZTS, the zend_signal_startup() call can
be omitted; otherwise, the missing call causes segmentation fault.
The PHP fix already was committed to upstream, but we still have to deal
with numerous unpatched versions remaining at large.

This fixes two issues:
- values for mutiple header fields with the same name
passed as arrays were converted to string;
- the type of field value wasn't preserved as required
by specification.

Node.js processes didn't exit after the changes in b9f7635e6be2,
as the quit command from port wasn't handled by the module.

We increase the number to the Unit object so that it lives forever.
This is necessary so that the garbage collector does not delete the Unit object.

The nxt_murmur_hash2() generated 4-byte hash that was stored in uintptr_t,
which was 8 bytes long on 64-bit systems. At each iteration, it took the
previous key and hashed it again.
The problem was that it took only the first 4 bytes of the key, and these
4 bytes were always zero on 64-bit big-endian system. That resulted in
equal keys at each iteration.
The bug was discovered on IBM/S390x.

The nxt_conf_map_object() function used nxt_int_t for NXT_CONF_MAP_INT, which
was 8 bytes long on 64-bit systems.
But the nxt_port_main_start_worker_handler() used it to map into the int field
of the nxt_common_app_conf_t structure, which was 4 bytes. As the result, on
a 64-bit big-endian system all the meaningful module type numbers were assigned
into the gap above the "type" field.
The bug was discovered on IBM/S390x.

The issue was caused by misplacement of allocated blocks in rbtree due
to broken comparison function if the distance between two allocations
did not fit into intptr_t. As the result, nxt_mp_free() could have
failed to find the allocation.
In particular, it was mostly observed when Unit was compiled with
musl C library on 32-bits systems.
This closes #118 issue on GitHub.

- Fixed handling of the "options" parameter in Socket() constructor;
- Now the connect() method returns "this";
- Deduplicated the address() method;
- Added missing "callback" argument to the end() method;
- Now the destroy() method returns "this";
- Added "timeout" argument type check in the setTimeout() method.

epoll changes are committed to the kernel before epoll_wait() or
on changes array overflow. In the latter case if there are errors
epoll_wait() timeout was not set to zero.

Timers that don't require maximum precision (most of them, actually) can be
triggered earlier or later within the bias interval.
To reduce wakeups by timers, the expire function now triggers not only all
timers that fall within the elapsed time, but also those whose bias falls
within this interval.

Delete/insert operation complexity for a red-black tree is O(log n),
where n is the total number of tree elements.
If all delete operations are performed before all insert operations,
the average number of tree elements during an operation will be
lower than in the mixed-operations case.

To optimize rbtree operations, all changes are stored in array and later
processed in batches.
The previous implementation of this mechanics had a number of design flaws.
Each change was saved in a new array entry; until the changes were applied,
the timer remained in an intermediate state (NXT_TIMER_CHANGING).
This intermediate state didn't allow to identify if time was going to be
disabled or enabled. However, the nxt_conn_io_read() function relied on
this information; as a result, in some cases the read timeout wasn't set.
Also, the nxt_timer_delete() function did not reliably track whether a timer
was added to the work queue. It checked the NXT_TIMER_ENQUEUED state of
a timer, but this state could be reset to NXT_TIMER_DISABLED by a
nxt_timer_disable() call or another nxt_timer_delete() call.
Now, instead of keeping the whole history of the timer's changes, the new
implementation updates the timer state immediately, and only one operation
is added to the array to add or delete timer in the rbtree according
to its final state.

LibreSSL uses high OPENSSL_VERSION_NUMBER, but has no SSL_CTX_add0_chain_cert().

There's nothing specific to Go language. This type of application object can
be used to run any external application that utilizes libunit API.

This issue was introduced in libunit commit (e0f0cd7d244a). All port
sockets in application should be in blocking mode whereas Unit itself
operates non-blocking sockets.
Having non-blocking sockets in application may cause send error during
intensive response packets generation.

According to RFC 7232:
| A 304 response cannot contain a message-body; it is always terminated
| by the first empty line after the header fields.
|
|
This was unintentionally disabled by 7b5026a0bdeb.

Router requests application start by sending port message with application
parameters to master. In response router gets application port. Stream id
used to link request and response. If application process terminates
unexpectedly (e.g. before ready state), it is required to notify router about
application start failure. For this purpose stream id is stored in process
initialization parameters.
Stream id sequentially incremented and starts from 1 in case of router
resurrection. New router application start stream id may coincide with
stream id of currently running/terminating application processes. In such
cases router may receive REMOVE_PID message with same stream id as used in
application start request and mistakenly reports application start failure.
This commit tries to avoid such errors by resetting stream for processes in
ready state.

_GNU_SOURCE is required there to expose off64_t and other types.

Router reconfiguration may lead to starting new application processes, opening
listen ports etc. These actions are asynchronous and require message
exchange with master process. Router stores reference for controller
(response) port in structure associated with reconfiguration process (tmcf).
The port used to provide reconfiguration response (either success or failed)
to controller.
This commit increases response port use counter to make sure port structure
not freed while router waits for result of asynchronous operations.

Previously, passing 0 resulted in reading the whole body and all negative
values raised an exception.
Now the behaviour is in consistentance with io.RawIOBase.read() interface,
and passing 0 returns empty (byte) string, while -1 results in reading the
whole body.

The pool is inherited from master process since changeset 854a1a440616.
