sasl: Add no_dot_erlang start script

Sometimes it is wanted to start erlang without loading the user dependent
.erlang file, for example in scripts and configure tests.
sasl: Add no_dot_erlang documentation and tests
wx: Fix initializations on mac osx

Remove dummy windows and move the console to gui app code before
wxWidgets gets initialized to prevent hangings on current wxWidgets svn
version.
wx: Enable configure flags --with-wxdir --with-wx-prefix on windows
wx: Fix cleanup of event handlers

Event handlers was not removed after objects/process had been
delete/died, which causes memory leakage and that fun's was
kept in the wx_server process. Code that might be purged and
the server died.
wx: Fix compiler warnings
wx: Fix compilation on old macs
wx: Fix looping debug printout

Find endless loop, if we wxe_master is killed we can't send messages
to it.
Fix reverting of implicit funs

Implicit funs parts in plain AST are no longer in concrete form since
Erlang/OTP R15.
Fix transformation of implicit funs in igor

Function erl_syntax_lib:analyze_implicit_fun/1 should not be called on
implicit external funs, as their parts can contain variables instead of
atoms and integers.
Remove a useless function clause in erl_syntax_lib
fix documentation
Fix confusing documentation about error handlers in SASL

The SASL documentation confusingly talks about a handler 'error_logger_mf_h'
which doesn't actually exist. The handler is named 'log_mf_h', and it and
all other error handlers used by SASL are part of stdlib, not SASL itself.
This patch makes the documentation clearer.
wx: Fix crash in wxe_server cleanup

Do not use disconnect event listener when we are exiting the port, it may
interfere with window destructions and cause a crash.
erts: Fix naming in erlang:monitor spec
[common_test] Don't hang netconf client when close-session times out

When the netconf server did not respond to the close-session request,
the call to ct_netconfc:close_session/2 would hang forever waiting for
the netconf client to terminate. This has been corrected. The client
will now always terminate (and take down the connection) if the
close-session request times out.
wx: wxListBox::Set crashes on wxWidgets 3.0 with NULL argument
wx: Update documentation links to wxWidgets
