bdc60306c7 parse_launch: make nicer log messages
Add two macros to build nicer element/pad name strings. The macros avoid
printing "(NULL)" and print the element type in addition to the name.

46a851b279 parse-launch: warn when still waiting to plug sub-pipelines after no-more-pads
The parse-launch API automagically handles dynamic pads and performs delayed
linking as needed, without any feedback about whether the linking succeeded or
not however. If a delayed dynamic link can't be completed for whatever reason,
parse-launch will simply wait in case a suitable pad appears later. This may
never happen though, in which case the pipeline may just hang forever.

Try to improve this by connecting to the "no-more-pads" signal of any element
with dynamic pads and posting a warning message for the related outstanding
dynamic links when "no-more-pads" is emitted.

Fixes #760003

'gst_element_post_message' takes the ownership of the message, so it
shall unref it when there is no post_message implementation. Otherwise

b427997119 element: Don't hold state lock all the time while sending an event
This lock seems to exist only to prevent elements from changing states while
events are being processed. However events are going to be processed
nonetheless in those elements if sent directly via pads, so protection must
already be implemented inside the elements for event handling if it is needed.

As such having the lock here is not very useful and is actually causing
various deadlocks in different situations as described in

2d427c75ae bin: Post a LATENCY message with async-handling=TRUE if the PLAYING state is reached
Otherwise each bin might have a different latency in the end, causing
synchronization problems.

The bin will still first handle latency internally as before, but gives the
overall pipeline the opportunity to update the latency of the whole pipeline
afterwards.

446b3e6ddc plugin: Don't do lossy shift on hash
In plugin is responsible for calculating a hash of the dependencies
in order to determine if the cache should be invalidated or not.
Currently, the hash combining method removes a bit of the original
have before combining with an addition. As we use 32bits for our hash
and shift 1 bit for each file and directory, that resulting hash only
account for the last 32 files. And is more affected by the last file.

Rotating technique (shifting, and adding back the ending bit), can be
use to make the addition non-commutative. In a way that different order
gives different hashes. In this case, I don't preserve this behaviour
because the order in which the files are provided by the OS is
irrelevant.

In most cases, the XOR operation is used to combine hashes. In this
code we use the addition. I decided to preserve the addition because
we make use of non-random hash ((guint) -1) in the algorithm for
matching files that are not really part of the hash (symlinks, special
files). Doing successive XOR on this value, will simply switch from
full ones, to full zero. The XOR used with whitelist has been preserved
as it's based on a fairly randomized hash (g_str_hash).

7e2aae7942 info: fix compiler warning with -Wpedantic and gcc 5
Gstreamer compiled with gcc 5.2 and -Wpedantic produces the
following warning:

'ISO C does not support '__FUNCTION__' predefined identifier [-Wpedantic]
  const char *s = __FUNCTION__;'

Since gcc 5 enables C99 by default, use __func__ if it's available
instead of the non-standard __FUNCTION__ (as suggested in [2]).

ca22e60b91 pad: Mark sticky events as sent on not-linked
Instead of re-sending sticky events over and over to a not-linked
pad, mark them as sent the first time. If the not-linked came from
downstream, it already received the events. If the pad is actually
not-linked, the sticky events will be rescheduled when the
pad is linked anyway.
