Unit 1.1 release

[Valentin V. Bartenev]

Hello,

I'm glad to announce a new release of NGINX Unit.  This is mostly a bugfix
release with stability and compatibility improvements.

Changes with Unit 1.1                                            26 Apr 2018

    *) Bugfix: Python applications that use the write() callable did not
       work.

    *) Bugfix: virtual environments created with Python 3.3 or above might
       not have worked.

    *) Bugfix: the request.Read() function in Go applications did not
       produce EOF when the whole body was read.

    *) Bugfix: a segmentation fault might have occurred while access log
       reopening.

    *) Bugfix: in parsing of IPv6 control socket addresses.

    *) Bugfix: loading of application modules was broken on OpenBSD.

    *) Bugfix: a segmentation fault might have occurred when there were two
       modules with the same type and version; the bug had appeared in 1.0.

    *) Bugfix: alerts "freed pointer points to non-freeble page" might have
       appeared in log on 32-bit platforms.
