Add a query to request allocation parameters and optionally a bufferpool as
well. This should allow elements to discover downstream capabilities and also
use the downstream allocators.
All functions in this file can access the structure field of a query directly.
This avoids having to call gst_query_get_structure() to get it, along with being
able to remove some function variables that were used to store the result of that
function.
Sprinkle some G_UNLIKELY(), return TRUE/FALSE constants, avoid an
unnecessary g_value_unset(), move g_value_init()+set_int64_range()
closer to where they're needed.
Don't create a new GValueArray copy for every single _add_buffering_range()
call, but append to the existing value array owned by the structure instead.
Added a new query type to retrieve informations about the areas of the
media currently buffered. See bug 623121.
API: gst_query_add_buffering_range
API: gst_query_get_n_buffering_ranges
API: gst_query_parse_nth_buffering_range
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.

Use gst_structure_id_empty_new() in combination with GST_QUARK
rather than gst_structure_id_new() when creating message, event,
query and taglist structures. Mostly just because we can.
Move MT safety to main description (it does not belong to Return: or Since:
statement). Add a few missing return docs. Downgrade a normal comment froma doc
comment. Fix a doc header to only contain symbol name.

API: Add URI query type. This is useful to query the URI
of a sink/source element and can be used by demuxers that
need to get data from other files.
This query should go upstream by default.

Add GstQueryType for custom queries instead of having to use the

* gst/gstutils.c: Remove check in gst_pad_query_convert() that
src_val must be positive, because that's not a requirement.
This causes problems with converting negative granulepos
values for Dirac.

redefined in the system headers. Fixes build
on opensolaris (#340016).
