* builds/windows/vc2010/script.bat: New windows batch file to copy
necessary dlg files from `submodules/dlg' to `src/dlg'. This file is
used as a pre-built event in visual studios.
* builds/windows/ftdebug.c: Added support for logging and logging related
public APIs.
(ft_debug_init): Updates to support the change of levels of tracing
components of FreeType at run-time.
(FT_Trace_Set_Level): New function to change the levels of tracing
components at run-time.
(FT_Trace_Set_Default_Level): New function to reset the levels of
tracing components back to default.
(FT_Set_Log_Handler, FT_Set_Default_Log_Handler, FT_Callback): Added
function definitions.
* builds/windows/vc2010/freetype.vcxproj.filters: Added `src/dlgwrap.c'.
* builds/windows/vc2010/freetype.vcxproj (AdditionalIncludeDirectories):
Added include files of dlg for `Debug' and `Debug Static' configurations
on both `x64' and `win32' platforms.
(PreprocessorDefinitions): Added `FT_LOGGING' for `Debug' and
`Debug Static' configurations on both `x64' and `win32' platforms. Added
`DLG_STATIC' for `Debug' configuration on `x64' and `win32' platforms.
(DisableLanguageExtensions): We need to disable the `/Za' option when
building dlg with FreeType as dlg strictly follows `C99' standards and
the Visual Studios produces unexpected behaviours when compiling a `C99'
file with `/Za' option enabled.
