- add G_VARIANT_TYPE_BYTESTRING, _BYTESTRING_ARRAY, _STRING_ARRAY
- remove g_variant_{new,get}_byte_array functions
- add g_variant_{new,get,dup}_bytestring{,_array} functions
- remove undocumented support for deserialising arrays of objectpaths
or signature strngs using g_variant_get_strv()
- add and document new format strings '^ay', '^&ay', '^aay' and '^a&ay'
- update GApplication to use the new API
- update GSettings binding code to use the new API
- add tests
Merge GVariant variable arguments support and put it under tests.
Also, remove the hack of the test case directly '#include'ing .c files
from glib/. Instead, create a non-installed gvariant-internal.h that
the tests can include and make the symbols in it visible on the symbol
table of the shared library. These symbols (as they are present in no
installed header files) are not part of the API of GLib.
Increase test coverage in a few other areas.
