While TCP and IPC socket duplicates are correctly closed on
fork+exec, file descriptors used for internal communication
within libxs are not. This patch fixes the problem.

The socket connecting using the inproc transport never
received the identity of the remote peer.
|
|
The scoket implementation for inproc transfer failed to flush
identity message. The result was that the identity message
was not delivered until after the user sent the first message.
The identity message was never delivered if the user
used the socket only to receive messages.

libxs (as opposed to libzmq) requires at least one I/O thread per
context. Thus, "no I/O thread available" error doesn't make sense
anyome.
This patch removes the code and the documentation.
It keeps the definition of EMTHREAD itself for backward compatibility.

is set to 'terminated'.

This patch introduces following features:
- XS_PLUGIN context option to add plugins to libxs
- XS_FILTER option to switch between different filter types
- Automatic loading of plug-ins is *not* implemented.
From the implementation point of view:
- standard prefix filter is implemented as a pluggable filter
- trie_t and mtrie_t are joined into a single class
- the code for 0MQ/3.1 compatibility is left in in the form of comments
- new test for testing re-subscriptions is added

The existing code for definining the XS_HAVE_* macros for the polling
mechanism may fail if the platform's `tr' command does not support the
GNU syntax. Replacing the hand-made declaration with autoconf macros
yields the same results on all platforms.

- Use consistent quoting in M4 macros
- Use portable M4sh shell constructs where possible
- More consistent indentation and line wrapping
- Split lists of files or functions on multiple lines to simplify adding
and removing elements from them
