c906ccb79f element: NULL the lists of contexts in dispose()

148ac71a1f pad: Keep IDLE probe hook alive during immediate callback
When the probe returns GST_PAD_PROBE_REMOVE and gets called concurrently
from the streaming thread while we're in the callback here, the hook has
already been destroyed by the time we've reacquired the object lock.
Consequently, cleanup_hook gets passed an invalid pointer.

Keep another reference to the hook alive to avoid this situation.

bb48c4c9f6 plugin: load plugins with unknown license strings
We shouldn't fail to load plugins just because we don't
recognise the license string. It's not our job to validate
licenses, and the license list is outdated and ambiguous
anyway.

Also add MPL-2.0 to the list, and fix some defunct license
URLs in the code comments.

Get rid of the hard-coded skip index, doesn't really buy us
much versus just skipping with a few strlens, and is harder
to maintain.

ed92fb2430 gsturi: Don't treat invalid format of uri as critical error
Normally uri is get from user input and invalid user input should not
be treated as critical error. Moved gst_uri_is_valid outside of
g_return_val_if_fail.

NULL uri is checked inside of gst_uri_is_valid and is correctly
treated as critical error, removed unneeded checks of NULL uri outside
of gst_uri_is_valid function.

add1f17c57 systemclock: Restore default clock mode to monotonic for non-linux system
Before the MR https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/829
Windows and macOS system clock used monotonic clock regardless of
selected clock mode. And because of clock resolution, we should prefer
monotonic over realtime unless realtime clock is selected explicitly.

8c08cdf9fe gstinfo: Improve usage of libdw for backtraces
When getting backtraces, we were always creating a new Dwfl context and then
discarding it. The problem with that is that it resulted in having to re-scan a
lot of information for every single backtrace.

In order to fix that issue, use a global on-demand Dwfl context and use it with
a lock.

Furthermore, we were scanning the mappings of the
process (dwfl_linux_proc_report) for *every single step* in the backtrace, and
that function is horrendously expensive (does sscanf on /proc/PID/maps
...). While there is a possibility that new mappings might be available (new
plugins being loaded for example), we can limit ourselves to just do it once per
backtrace.

These two modifications speed up the elements_leaks unit test (which traces all
pads with full backtraces) by a factor of 6.

Partially fixes #567

7f29361488 parse: Don't do delayed property setting for top-level properties.
If a property is supplied to gst-launch-1.0 to set on a property that
implements GstChildProxy, it would always accept any property name
and try to set it later. This means that (for example) decodebin
will accept and not complain about property names that can never exist like:

gst-launch-1.0 videotestsrc ! decodebin NON-EXISTING_PROPERTY=adsfdasf ! fakesink

Instead, only try to do deferred property setting for property names
that contain the :: separator that indicates it's a setting on a child
that might appear later.

bb77f41abf systemclock: Reorganize defined checks for parts of GstSystemClock
The gst_system_clock_get_internal_time and
gst_system_clock_get_resolution functions had some nested defined checks
making this code somewhat harder to reason about and much harder to
change. The logical meaning of the checks has changed but the actual
code coming out of the pre-processor should not have changed
significantly. The main logical change was flattening the checks for
existence of posix timing functionality, from what I can tell these
functions aren't available on Windows where they were trying to be
included. I have checked the Linux and macOS output and they are
functionally unchanged.

1a8dfdfc54 Introduce gst_element_request_pad_simple
The name `gst_element_get_request_pad()` is confusing to people
learning GStreamer. `gst_element_request_pad_simple()` aims at
providing the exact same functionality, while making it more
explicit it is a simplified `gst_element_request_pad()`.

`gst_element_request_pad_simple()` is consistent with other
functions such as `gst_element_seek_simple`.

This commit deprecates `gst_element_get_request_pad()` so that a
compilation warning is emitted when used and incite developers
to use the more explicit `gst_element_request_pad_simple()`.

Protect clearing probes against concurrent modification which might happen
due to dispose does NOT guarantee that the object is not used anymore, as
it could be referenced again and so being continued used.
So, as in the rest of places where probes hook list is used, on dispose
it should be accessed holding the mutex "GST_OBJECT_LOCK (pad);" as
GHookList is not thread-safe.

12661d90a3 value: fix parsing of explicit value casts
Since acdb4ce03d , parsing of the
value for a property can use the pspec to determine what type
a value should be casted to.

However, this broke the case where the value is explicitly casted
to a type (eg <(float) 0.0>). In that situation, we want to respect
the casting decision, and only use the pspec to perform "implicit"
casts.
