This closes #182 issue on GitHub.
Thanks to 洪志道 (Hong Zhi Dao).

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.

Thanks to Julian Brost.

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().
|
|
Previously, test failed if openssl was unable to load config info,
or the system's openssl.cnf was picked up, which is wrong as well.

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.

Currently we consider any changes with revision other than 1 as
packages-specific, thus there is no need to include such entries
to the generic Unit change log.

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.
