Before this patch gst_init would intercept --help, causing for example
cheese's --help to look like this:
[hans@shalem cheese]$ cheese --help
Usage:
cheese [OPTION...] - GStreamer initialization
Help Options:
-h, --help Show help options
--help-all Show all help options
--help-gst Show GStreamer Options
gst_init is the only gfoo_init function which does this.

Doing it after every single create() is not very efficient and not necessary.
Especially on network file systems fstat() is not cached and causes network
traffic, making the source possibly unusable slow.

API: gst_value_array_append_and_take_value
API: gst_value_list_append_and_take_value
We were already using this internally, this makes it public for code
which frequently appends values which are expensive to copy (like
structures, arrays, caps, ...).
Avoids copies of the values for users. The passed GValue will also
be 0-memset'ed for re-use.
New users can replace this kind of code:
gst_value_*_append_value(mycontainer, &myvalue);
g_value_unset(&myvalue);
by:
gst_value_*_append_and_take_value(mycontainer, &myvalue);

By default when the script is about to exit (normally or due to an error),
it checks whether $ERROR_LOG file exists. If the log file exists, the
script prints a "Failures: " message prefix and dumps the log file to the
output.
Apparently the log file is always created and if the update/build is
successful, the script finishes with a bit misleading "Failures: " message.
An improvement provided with this change lets the log file to be created as
needed, i.e. if there's an error message to be printed. If the file
doesn't exists, the script prints a "Update done" message which clearly
indicates success.

During FLUSH_START the query needs to be unblocked already, otherwise
it can lead to deadlocks if the FLUSH_START is the result of something
done from the streaming thread of the srcpad (the queue will never be
emptied!).
Fixes some deadlocks during flushing.
And store queue items differently to not accidentially read
already unreffed queries when flushing. Queries are owned by
upstream and not us.
But do this only for events that are not dropped by flushing,
i.e. do it only for everything except SEGMENT and EOS.
Without this we might drop a CAPS event if flushing happens
at an unfortunate time and nobody is resending the CAPS event.
