67ae0ad225 adapter: Add methods to query current offset
API: gst_buffer_prev_offset
API: gst_buffer_get_offset_from_discont

The gst_buffer_get_offset_from_discont() method allows retrieving the current
offset based on the GST_BUFFER_OFFSET of the buffers that were pushed in.

The offset will be set initially by the GST_BUFFER_OFFSET of
DISCONT buffers, and then incremented by the sizes of the following
buffers.

The gst_buffer_prev_offset() method allows retrievent the previous
GST_BUFFER_OFFSET regardless of flags. It works in the same way as
the other gst_buffer_prev_*() methods.

8487133114 controlpoint: change the padding to be of arch-independent size
The default padding I introduced in d4f81fb4e6 is
actually only 4 pointers and on 32bit platforms already smaller than the union.
Replace it with a fixed 64byte padding. Don't add the normal padding for now.

d4f81fb4e6 controller: add the missing abi padding
While this technically is an abi break, we decided to do this:
1) the struct is documented to be internal
2) the struct is alloced and freed inside the library
3) there are no public methods that receive or return instances
4) the only code known to use this struct are classes containd here

900110c6dc basesrc-test: Fix race testing segment update
As this test is using a short sleep (GST_USECOND, which is 10ms
in microsecond), sometimes that EOS event is received before the
loop in basesrc have run _do_seek() and pushed the update segment.
To solve this issue, we wait for the initial segment (and flush it)
then we wait for the second segment before sending EOS.

a041d8862d baseparse: only post 'no valid frames' error if buffers were received
Otherwise baseparse will consider empty streams to be an error while
an empty stream is a valid scenario. With this patch, errors would
only be emitted if the parser received data but wasn't able to
produce any output from it.

This change is only for push-mode operation as in pull mode an
empty file can be considered an error for the one driving the
pipeline

Includes a unit test for it

fdfc6dc983 basesrc: preserve seqnum of eos events sent by the user
Store the eos event seqnum and use it when creating the
new eos event to be pushed downstream. To know if the eos
was caused by the eos events received on send_event, a
'forced_eos' flag is used to use the correct seqnum on
the event pushed downstream.

Useful if the application wants to check if the EOS message
was generated from its own pushed EOS or from another source
(stream really finished).

Also adds a test for this

afbba8974a tests: fix spurious failure in test_collect collectpads test
pop() in collected callback.

There were three threads in the test cases that hanged: the test thread and two
threads that push buffers. Each thread push one buffer on one pad. There are
two pads in the collectpads so the second buffer will trigger the
collect-callback.

This is what happens when the hang occurs:

The first thread pushes a buffer and initializes a cookie to the value of a
counter in the collectpads object and waits on a cond for the counter to change
and for someone to consume the buffer (i.e. _pop() it).

The second thread pushes a buffer and calls the collected callback, which
signals the cond that the test thread is waiting for.

The test thread pops both buffers (without holding any lock). Each call to
_pop() increases the counter broadcasts the condition that the first thread is
now waiting for. It then joins both threads (hangs).

The first thread wakes up and returns, since its buffer has been consumed.

The second thread starts executing again. When the callback, called by the
second thread, has returned it initializes a cookie to the value of a counter,
which has already prematurely been increased by the test thread when it popped
the buffers, and wait's on a cond for the counter to change and for someone to
consume the buffer (i.e. _pop() it). Since the buffer has already been poped
and the counter has already been increased it will be stuck forever.

1b87a07d8e adapter: remove _try_to_merge_up()
It causes the timestamp to go wrong, should not cause much of a performance
increase and in the cases where it is faster, it is broken in 0.10 as well.
We should try to review this when rewriting the adapter for 0.11 memory
features.

772c58e255 controller: expand the api to offer functions for plain and GValue arrays
Rename the _get_value_array() functions to _get_g_value_array() and reintroduce
the former to operate on plain unboxed c datatypes (like in 0.10). The _g_value
variants are for bindings while the _value ones are more suited to processing
in elements.

38b96e6c8c buffer: improve the buffer memory methods
gst_buffer_take_memory -> gst_buffer_insert_memory because insert is what the
method does.
Make all methods deal with ranges so that we can replace, merge, remove and map
a certain subset of the memory in a buffer. With the new methods we can make
some code nicer and reuse more code. Being able to deal with a subset of the
buffer memory allows us to optimize more cases later (most notably RTP headers
and payload that could be in different memory objects).
Make some more convenient macros that call the more generic range methods.

7b0e4f27fb memory: make _new_wrapped take user_data and notify
Make it possible to configure a GDestroyNotify and user_data for
gst_memory_new_wrapped() this allows for more flexible wrapping of foreign
memory blocks.

83002ac63e typefind: pass extensions as comma-separated list in a simple string
Fix annoying gst_type_find_register() function signature. A simple
string with comma-separated extensions works just as well and saves
lines of code, casts, relocations and ultimately kittens.

5e4c13fc97 controller: constructures for control sources return GstControlSource
Don't return the specific types. In most cases there is no specific api there
anyway.

a521252845 Add new GstMapInfo
Use a structure to hold info about the mapping. The application then keeps track
of this state and we can use it to unmap the memory again later.
