* vladdu/jinterface_map_sortkeys:
  Improve sorting order of keys in a map

The implementation sorted keys differently for different Java versions
(probably due to different hashing algorithms), so we switch it to use
LinkedHashMap where the order is deterministic.

This is a regression of 4390e43558 in the OtpOutputStream class.

We can not call java.util.zip.DeflaterOutputStream.close() in the finally
block of the OtpOutputStream.write_compressed(OtpErlangObject, int) method.
This leads to a NullPointerException when encoding "{}" which is caused by
the DeflaterOutputStream trying to write bytes to the deflater which was
"destroyed" by calling java.util.zip.Deflater.end().
Further possibilities to call close() in the finally block are not suitable
either (see the comment in the source). This leaves no choice but to revert
the change from 4390e43558 in this class (and add an appropriate test case).

Term tag matching switch statement was missing external fun tag.

This gives an error when building the docs.

OTP-12691

Adding these two methods to the OtpErlangObject abstract class makes possible
implementing of pattern matching and variable binding for all types of Erlang
terms. Particular implementations may vary and include additional classes to
define Variable placeholder objects and Bindings objects. Also Parser class
may be added to facilitate creating complex patterns and terms.

The purpose of this commit is to provide low level interface base methods
sufficient for variety of higher level pattern matching/variable binding
implementations.

OtpErlangMap class is re-designed for efficiency (it is based on HashMap now).

All changes are backward-compatible. Detailed test cases implemented.

Transport factory basic implementation added. This makes possible
creating connections between nodes using ssh channels for example.
Default transport factory based on standart Socket/ServerSocket
classes is provided. Modifications are backward compatible.
