Implement new telnet logging system
Add and improve test cases

Also correct some issues found during test
Implement tests for logging traffic for multiple telnet connections

Also fix remaining problems in source code
Make it possible to use raw telnet logs in parallel test case groups
Fix remaining problems using raw telnet logging for parallel test cases
Make temporary fix of problem that sometimes causes the ct_util server to die
Add documentation about logging in the ct_telnet module
Add verification terms for the unix_telnet test case
ssl: Add workaround in test code for openssl s_client bug
Fix representation of named funs in syntax_tools

A named fun's name is a variable name, its type in syntax_tools is named_fun_expr.
Make it easier to revert +M<S>acul default
Minor update of INSTALL.md

Allow making the system with --enable-native-libs

The HiPE compiler crashes when trying to compile these files because
it does not currently support maps. So, add a -compile(no_native)
attribute to these files to allow the system to be made even when
configured with --enable-native-libs.

This is a temporary fix and will be removed when the HiPE compiler
gets proper support for maps.
