Fix to VHDL scanner.

The following code should produce two groups, each containing one page, within the same documentation scope,
currently it nests these groups and pages, resulting in incorrect documentation.

--! \defgroup group1 Group 1
--! \{
--!   @brief Group 1
--! \}

--! \ingroup group1
--! \{
--! \page group1_page1 Page 1
--! \verbatim
--!  Some Page 1 text
--! \endverbatim
--! \}

--! \defgroup group2 Group 2
--! \{
--!   @brief Group 2
--! \}

--! \ingroup group2
--! \{
--! \page group2_page1 Page 1
--! \verbatim
--!  Some Page 1 text
--! \endverbatim
--! \}

Similar C code to demonstrate the correct output.

//! \defgroup group1 Group 1
//! \{
//!   @brief Group 1
//! \}

//! \ingroup group1
//! \{
//! \page group1_page1 Page 1
//! \verbatim
//!  Some Page 1 text
//! \endverbatim
//! \}

//! \defgroup group2 Group 2
//! \{
//!   @brief Group 2
//! \}

//! \ingroup group2
//! \{
//! \page group2_page1 Page 1
//! \verbatim
//!  Some Page 1 text
//! \endverbatim
//! \}

Wrong UTF 8 codes

The utf-8 code for eta was identical to the code for theta and the code for Prime was identical to the one for prime

Bug 436885 - c-source and h-source missing for latex

Not only for Man pages the extra returns are necessary but also for LaTeX output.
The change in filedef.cpp is a direct consequence of t the bug report.
The groupdef.cpp has been tested on propriety code and the namespacedef.cpp and dirdef.cpp directly follow from code similarity.

Original title does not cover problem anymore. Problem has evolved to that when clicking on the name for the source file (in LaTeX) a jump to the beginning of the document was made. This problem is fixed with this patch.
