Minor modification of one test.

XML: Improved format of written XML documents, simplified code.

DB: Fixed a bug in GWEN_DB_WriteVarValueToBuffer()

Fixed a bug (created files had no file access rights: #178).

Incremented version.

Applied a patch provided by pkzw via bug ticket #130.

Merge branch 'master' into maint

Prepared release 5.1.0.

Added a function which is needed by AqBanking to automatically import
old settings into AqBanking6, so the API changed by an addition, thus
incrementing the minor version number is already necessary.

Incremented version number (need to do SO_VERSION+, SO_AGE+ before next release).

Added function GWEN_SyncIo_Helper_WriteFile().

Added missing folder "test_framework" to DIST_SUBDIRS.

Prepared release 5.0.0.

Result of "make format".

Removed modules not used by any application.

- GWEN_IdList: Use GWEN_IdList64, which is properly tested
- GWEN_PointerList: Use GWEN_SimplePtrList, which is properly tested

Fixed many compiler warnings.

test framework: Use gwen_cb flag for function definition, adapt.

typemaker2: Fixed compiler warnings.

typemaker2: Added flag for virtual functions: "gwen_cb"

This flag adds "GWENHYWFAR_CB" to definitions of virtual functions.

More work on test framework.

test framework: Add paramsDb.

- this can be used to convey params to tests (used by AqDatabase)

Fix callback declarations with GWENHYWFAR_CB (for mingw/windows)
