ose: Add ifdefs for HAVE_UDP
ose: Implement tcp inet driver for OSE

The inet driver for OSE has to handle signals instead of selects
and thus the wrappers for ready_input/output are a little bit
different. However the majority of the inet code remains the same.
ose: Fix bug when hunting for signal proxy

Sometimes the wrong signal, i.e. a read reply, would be
received from this non-selective receive.
ose: Prepare slave for running on OSE

This change relies on the assumption that all arguments before the last --
to the parent beam should be left as they are.
ose: fix for packet_bytes in fd/spawn driver.
ose: Fix erts assert failed printouts
wx: Send destroy message direct

Messages was routed via the wxe_server process, which caused process
to never get the message.
Merge branch 'dgud/test_server/throw_skip'

* dgud/test_server/throw_skip:
  test_server: Allow init_per_ function to throw skip
ssh: Added option negotiation_timeout for ssh:daemon

This option is for closing a connection where the client connects, but then do nothing except keeping server resources.
ssh: added daemon option 'parallel_login', default false
erts: Reduce runtime of test port_SUITE:close_deaf_port

as it fails with timeout sometimes.
Change the subtag used for maps from 0xB to 0xF

The subtag chosen for maps breaks crucial assumptions in other parts of
the system, in particular the native code generation scheme used in the
HiPE compiler. Therefore it is better to use 'the other' unused subtag.

The main change here is the use of 0xF subtag for maps instead of 0xB.
The rest of the differences are changes to and additions of comments.

One more comment from my part.
I noticed that the file contains the following two lines:

The comment of the second line is most certainly a copy and paste error
and should be appropriately fixed by the OTP developers. More importantly,
it would be great if that subtag (0x7) turned out to be unused and could
be used for maps instead of the 0xF one. This might turn out very handy
in the future. I can elaborate on this, if needed.

Document an escript:create/2 hidden feature

escript:create/2 accepts a 3-elements tuple containing files and
zip:create/3 options to build a zip file.

Also had to update zip typespecs to allow referral from escript docs.
