abdafb0d64 protection: add GstProtectionMeta to support protected content
In order to support some types of protected streams (such as those
protected using DASH Common Encryption) some per-buffer information
needs to be passed between elements.

This commit adds a GstMeta type called GstProtectionMeta that allows
protection specific information to be added to a GstBuffer. An example
of its usage is qtdemux providing information to each output sample
that enables a downstream element to decrypt it.

This commit adds a utility function to select a supported protection
system from the installed Decryption elements found in the registry.
The gst_protection_select_system function that takes an array of
identifiers and searches the registry for a element of klass Decryptor that
supports one or more of the supplied identifiers. If multiple elements
are found, the one with the highest rank is selected.

This commit adds a unit test for the gst_protection_select_system
function that adds a fake Decryptor element to the registry and then
checks that it can correctly be selected by the utility function.

This commit adds a unit test for GstProtectionMeta that creates
GstProtectionMeta and adds & removes it from a buffer and performs some
simple reference count checks.

199c8ba561 docs: design: fix some 0.10-isms in GstSegment docs
1) segment.accum -> segment.base

2) Refer to GstSegment members as S.foo instead of
NS.foo, the event is now called a segment event
rather than newsegment event.

3) There's no more abs_rate field in GstSegment,
and there never was an abs_applied_rate field.

fc765592a1 meta: Add GstNetControlMessageMeta
GstNetAddress can be used to store ancillary data which was received with
or is to be sent alongside the buffer data.  When used with socket sinks
and sources which understand this meta it allows sending and receiving
ancillary data such as unix credentials (See `GUnixCredentialsMessage`)
and Unix file descriptions (See `GUnixFDMessage`).

This will be useful for implementing protocols which use file-descriptor
passing in payloaders/depayloaders without having to re-implement all the
socket handling code already present in elements such as multisocketsink,
etc.  This, in turn, will be useful for implementing zero-copy video IPC.

This meta uses the platform independent `GSocketControlMessage` API
provided by GLib as a part of GIO.  As a result this new meta does not
require any new dependencies or any conditional compliation for
portablility, although it is unlikely to do anything useful on non-UNIX
platforms.

6ec3c4bc66 utils: Add gst_bin_sync_children_states()
gst_bin_sync_children_states() will iterate over all the elements of a bin and
sync their states with the state of the bin. This is useful when adding many
elements to a bin and would otherwise have to call
gst_element_sync_state_with_parent() on each and every one of them.

154eefecc9 Don't compare booleans for equality to TRUE and FALSE
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

Also normalize booleans in a few places.

45c61db152 downloadbuffer: improve start/stop in buffering query
The start and stop should represent the currently downloading region.
The estimated-total should represent the remaining time to download
the currently downloading region. This makes it a lot more useful
for applications because they can then use those values to update
the fill region and use the estimated time to delay playback.
Update the docs with this clarification.

103a40b6ce bufferpool: Add method and virtuals to set flushing state
Currently there is no other way to unlock a buffer pool other then
stopping it. This may have the effect of freeing all the buffers,
which is too heavy for a seek. This patch add a method to enter and
leave flushing state. As a convenience, flush_start/flush_stop
virtual are added so pool implementation can also unblock their own
internal poll atomically with the rest of the pool.  This is fully
backward compatible with doing stop/start to actually flush the pool
(as being done in GstBaseSrc).
