This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

For now, don't show a g_warning() for empty tag strings and NULL
tags with non-git versions; we should wait for the fixes in our
plugin modules to make it into a release before we enable this
unconditionally.
Add functions to create a new tag list and set tags in one go, which
is nice for use in combination with functions that take ownership of
the taglist, such as gst_event_new_tag() or gst_element_found_tags().
API: add gst_tag_list_new_full()
API: add gst_tag_list_new_full_valist()
Also warn if an element or application tries to add a field with an
empty string to a structure (NULL strings are still needed and
allowed though) and do all those checks in the right function.
Fixes#559643.
Original commit message from CVS:

* tests/check/gst/gsttag.c:
More complete unit tests. Fix handling of empty taglists (they were
not merged before).
Original commit message from CVS:
* gst/gststructure.c: (gst_structure_id_set_value):
If someone tries to set a non-UTF8 string field on a structure,
don't just print a warning, but also ignore the request and do
not change/add that field to the structure.
* tests/check/gst/gsttag.c: (GST_START_TEST), (gst_tag_suite):
Test for the above.
