When the shm buffer is sent over the port queue, it needs to be completed
because it's sent over the port socket.

This makes the "sed" instruction simpler and more portable, as the previous
variant didn't work well on BSD systems due to the "\s" metacharacter.

Thanks to Sergey A. Osokin <osa@FreeBSD.org.ru> for spotting this issue.

Also, this should prevent accidentally creating a version 1.0.0 package.

Globally installed modules require a globally installed libunit.
The "binding_pub.gyp" file is the correct version, otherwise linked module
may have unresolved symbols because libunit is not linked.

This fixes memory and shm file descriptor leakage that occurred when a large
request body was passed via shared memory.  The leakage was caught with the
"test_settings_body_buffer_size" test.  The main condition is the
"body_buffer_size" value exceeding 10 Mb (a shm segment).  Thus, the router was
forced to split the body into several shm segments, but these buffers were not
freed because of dummy completion handlers.

The certificate is selected by matching the arriving SNI to the common name and
the alternatives names.  If no certificate matches the name, the first bundle in
the array is chosen.
