We want to use the flag/enum nicks here, not only because they
are shorter but also because in case of element-specific enums
and flags we abuse the enum/flag name field for the description,
and we don't want that printed in the dot file.

It's used by the debugging and tracer subsystem and in various files, make it
a central thing that is initialized independ of the existence of those
subsystems.
Only print interesting caps features, don't
append (memory:SystemMemory) to all caps,
which makes them much more unwieldy and
harder to read. Also use internal function
to get caps features so that our printing
has no side effects on the caps.

gstdebugutils.c: In function 'gst_debug_bin_to_dot_data':
gstdebugutils.c:683:530: error: 'return' with no value, in function returning non-void [-Werror]
g_return_if_fail (GST_IS_BIN (bin));
GST_DEBUG_BIN_TO_DOT_FILE() would cause a segfault whenever it encountered an
element's caps that had a field value being NULL. Such fields are successfully
handled e.g. by GST_*_OBJECT(), and with this patch so does
GST_DEBUG_BIN_TO_DOT_FILE(). Even if string fields with a NULL value are
not supposed to be valid in caps, such caps can be created.

The linking behaviour of external variables that are not initialized
in the compilation unit where they are defined is undefined. On OS X
this causes a linking failure when statically linking GStreamer.
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.
Handle virtual links between ghost and proxypads when iterating pads instead of
when linking. Besides using less code this provides a more accurate picture.
Remove gst_pad_get_negotiated_caps(), it does not realy do what it says,
gst_pad_get_current_caps() returns the currently negotiated caps on the pad
correctly.
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.

dot does not take the head/tail labels into account. For unfixed caps they get
quite large. Double the padding to make it sort of readable in more cases. Also
make normal font bigger and caps-label font smaller to increase our luck.
