WSDLtoCorba: handling different forms of sequences

Related to CXF-5254.
Introduced the concept of (un)wrapped arrays and sequences (as suggested
by Daniel Kulp). Element declarations of xsd:complexTypes may be
sequences/arrays (minOccurs!=0 || maxOccurs!=0) and they appear as a
sequence of elements with the same name in XML instances (unwrapped
form).
However when mapping IDL to WSDL Corba Binding, sequences are always
wrapped.

[CXF-5254] Correct handling of wrapped and unwrapped sequences

Corba Binding allows to set "wrapped" flag on sequences/arrays. It is
used at runtime to correctly produce events related to Corba-XML
mapping.
