1418e9e85c utils: use caps when getting a compatible pad by template
Do not ignore the caps argument when requesting a pad by template.

This is particularly harmful when the pad caps query by default
returns ANY so it will match the first template instead of the
one that actually intersects with the caps.

4d4e436376 Add GstParentBufferMeta
A core meta which helps implement the old concept
of sub-buffering in some situations, by making it
possible for a buffer to keep a ref on a different
parent buffer. The parent buffer is unreffed when
the Meta is freed.

This meta is used to ensure that a buffer whose
memory is being shared to a child buffer isn't freed
and returned to a buffer pool until the memory
is.

5bdd92be75 clock: Fix _STIME_FORMAT macros
This macro didn't work well as it relied on the sign on the last
divided number (number of days). This value is most of the time
zero, and zero is considered positive in printf. Instead, deal with
the sign manually, and resuse the original macros for the rest. This
actually simplify the macro a lot.

So from this point, the remaining warning for libgstreamer are about

5cab2e14c4 clock: Add signed time utilities
Add utility to print signed value of time. This is useful to
trace running time values in gint64 or GstClockTimeDiff values.
Additionally, define GST_CLOCK_STIME_NONE to indicate an invalid
signed time value and validation macro. New macros are:

GST_CLOCK_STIME_NONE
GST_CLOCK_STIME_IS_VALID
GST_STIME_FORMAT
GST_STIME_ARGS

d61ba38118 memory: provide a mem_map_full that takes the GstMapInfo
Follow up of 7130230ddb

Provide the memory implementation the GstMapInfo that will be used to
map/unmap the memory.  This allows the memory implementation to use
some scratch space in GstMapInfo to e.g. track different map/unmap
behaviour or store extra implementation defined data about the map
in use.

fe3249b0e1 clock: Add GST_CLOCK_FLAG_NEEDS_STARTUP_SYNC and related API
gst_clock_wait_for_sync(), gst_clock_is_synced() and gst_clock_set_synced()
plus a signal to asynchronously wait for the clock to be synced.

This can be used by clocks to signal that they need initial synchronization
before they can report any time, and that this synchronization can also get
completely lost at some point. Network clocks, like the GStreamer
netclientclock, NTP or PTP clocks are examples for clocks where this is useful
to have as they can't report any time at all before they're synced.

7130230ddb memory: provide a mem_unmap function that takes the flags to unmap
There are gstmemory's available that operate in two memory domains
and need to ensure consistent access between these domains.

Imagine a scenario where e.g. the GLMemory is mapped twice in both
the GPU and the CPU domain.  On unmap or a subsequent map, it would
like to ensure that the most recent data is available in the memory
domain requested.  Either by flushing the writes and/or initiating a
DMA transfer.  Without knowing which domain is being unmapped, the
memory does not know where the most recent data is to transfer to
the other memory domain.

Note: this still does not allow downgrading a memory map.

e9c15d5321 memory: gst_memory_share may fail to exclusively lock the parent memory
Now that locking exclusively dows not always succeed, we need to signal
the failure case from gst_memory_init.

Rather than introducing an API or funcionality change to gst_memory_init,
workaround by checking exclusivity in the calling code.

ad4569c893 miniobject: disallow a double write/exclusive lock
gst_memory_lock (mem, WRITE | EXCLUSIVE);
gst_memory_lock (mem, WRITE | EXCLUSIVE);

Succeeds when the part-miniobject.txt design doc suggests that this should fail:

  "A gst_mini_object_lock() can fail when a WRITE lock is requested and
  the exclusive counter is > 1. Indeed a GstMiniObject object with an
  exclusive counter 1 is locked EXCLUSIVELY by at least 2 objects and is
  therefore not writable."

b174ec6903 gst/gst.c: Add a warning about DllMain to prevent misuse
DllMain should not be relied on for anything except storing the DLL handle.
It should also not be defined for static builds, but doing so is not

f9e5178dd1 gstvalue: Add GstFlagSet type
GstFlagSet is a new type designed for negotiating sets
of boolean capabilities flags, consisting of a 32-bit
flags bitfield and 32-bit mask field. The mask field
indicates which of the flags bits an element needs to have
as specific values, and which it doesn't care about.

This allows efficient negotiation of arrays of boolean
capabilities.

The standard serialisation format is FLAGS:MASK, with
flags and mask fields expressed in hexadecimal, however
GstFlagSet has a gst_register_flagset() function, which
associates a new GstFlagSet derived type with an existing
GFlags gtype. When serializing a GstFlagSet with an
associated set of GFlags, it also serializes a human-readable
form of the flags for easier debugging.

It is possible to parse a GFlags style serialisation of a
flagset, without the hex portion on the front. ie,
+flag1/flag2/flag3+flag4, to indicate that
flag1 & flag4 must be set, and flag2/flag3 must be unset,
and any other flags are don't-care.
