c6c6ad2667 meson: update glib minimum version to 2.56
In order to support the symbol g_enum_to_string in various
project using GStreamer ( gst-validate etc.), the glib minimum
version should be 2.56.0.

Remove compat code as glib requirement
is now > 2.56

Version used by Ubuntu 18.04 LTS

e9085043c1 Don't use glib format modifiers with sscanf or printf
We do not have a way to know the format modifiers to use with string
functions provided by the system. `G_GUINT64_FORMAT` and other string
modifiers only work for glib string formatting functions. We cannot
use them for string functions provided by the stdlib. See:
https://developer.gnome.org/glib/stable/glib-Basic-Types.html#glib-Basic-Types.description

F.ex.:

```
 ../tools/gst-stats.c:921:11: error: too many arguments for format [-Werror=format-extra-args]
   printf ("Number of Buffers passed: %" G_GUINT64_FORMAT "\n", num_buffers);

../tools/gst-stats.c:922:11: error: unknown conversion type character 'l' in format [-Werror=format=]
   printf ("Number of Events sent: %" G_GUINT64_FORMAT "\n", num_events);

b2f9808722 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

77b4bc44ba tests: Add some code to replay and analyse netclientclock
This takes readings in the form of ...

<local_1> <remote_1> <remote_2> <local_2>

... with one observation per line, and then replays it using the
netclientclock code.

The output is the statistics structure emitted by the netclientclock,
which can then be analysed and tuned once we get those readings for
potential edge-cases.

It should be possible to find some inputs with "bad" data and convert
this into a unit test for future tweaks to run against.

5d6635f9b4 tools/gstreamer-completion: Complete option & property values on bash 3.2
Bash 3's completion doesn't split words by characters in
COMP_WORDBREAKS. In particular it doesn't split at "=" signs. Now
_gst_launch_parse handles both bash 3 and 4 format of COMP_WORDS.

Note that "${cur%%=*}" means cur's value with the longest possible match
of "=*" deleted from the end; "${cur#*=}" means cur's value with the
shortest possible match of "*=" deleted from the beginning. See
http://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html

Regardless of the version of bash running the unit tests, I can test for
both behaviours because the unit test populates COMP_WORDS manually. So
this tests the bash 3 behaviour:

    test_gst_inspect_completion --gst-debug-level=4

and this tests the bash 4 behaviour:

    test_gst_inspect_completion --gst-debug-level = 4

f586e34a50 tools/gstreamer-completion: Bash 3.2 compatibility fixes
Compatible with bash 3.2; doesn't require the bash-completion package at
all (though the easiest way to install this script is still to install
bash-completion, and then drop this script into /etc/bash_completion.d).

Note that bash 3 doesn't break COMP_WORDS according to characters in
COMP_WORDBREAKS, so "property=val" looks like a single word, so this
won't complete property values (on bash 3). Similarly,
"--gst-debug-level=<TAB>" won't complete properly (on bash 3), but
"--gst-debug-level <TAB>" will.

For that reason, I now offer "--gst-debug-level" etc as completions
instead of "--gst-debug-level=".

Functions "_init_completion" and "_parse_help" were provided by the
bash-completion package >= 2.0; now I roll my own equivalent of
"_parse_help", and instead of "_init_completion" I use
"_get_comp_words_by_ref" which is available from bash-completion 1.2
onwards. If the bash-completion package isn't available at all I use
bash's raw facilities, at the expense of not completing properly when
the cursor is in the middle of a word.

The builtin "compopt" doesn't exist in bash 3; those users will just
have to live with the inconvenience of "property=" completing to
"property= " with a trailing space. Property values aren't completed
properly anyway on bash 3 (see above).

"[[ -v var ]]" to test whether a variable is set, also doesn't exist in
bash 3. Neither does ";;&" to fall through in a "case" statement.

In the unit tests:

* On my system (OS X), "#!/bin/bash" is bash 3.2, whereas
  "#!/usr/bin/env bash" is the 4.2 version I built myself.
* I have to initialise array variables like "expected=()", or bash 3
  treats "+=" as appending to an array already populated with one empty
  string.

020dd3bbf3 tools/gstreamer-completion: Support gst-inspect, and gst-launch element properties
Completes options like "--gst-debug-level" and the values of some of
those options; completes gst-launch pipeline element names, property
names, and even property values (for enum or boolean properties only).

Doesn't complete all caps specifications, nor element names specified
earlier in the pipeline with "name=...".

The GStreamer version number is hard-coded into the completion script:
This patch is off the master branch and has the version hard-coded as
"1.0"; it needs to be updated if backported to the 0.10 branch. You
could always create a "gstreamer-completion.in" that has the appropriate
version inserted by "configure", but I'd rather not do that. The
hard-coded version is consistent with the previous implementation of
gstreamer-completion, which had the registry path hard-coded as
~/.gstreamer-1.0/registry.xml.

Note that GStreamer 0.10 installs "gst-inspect" and "gst-inspect-0.10".
"gst-inspect --help" only prints 4 flags (--help, --print, --gst-mm,
gst-list-mm) whereas "gst-inspect-0.10 --help-all" prints the full list
of flags. The same applies to "gst-launch" and "gst-launch-0.10".
GStreamer 1.0 only installs "gst-inspect-1.0", not "gst-inspect".

Requires bash 4; only tested with bash 4.2. Requires "bash-completion"
(which you install with your system's package manager).

Put this in /etc/bash_completion.d/ or in `pkg-config
--variable=compatdir bash-completion`, where it will be loaded at the
beginning of every new terminal session;
or in `pgk-config --variable=completionsdir bash-completion`, renamed to
match the name of the command it completes (e.g. "gst-launch-1.0", with
an additional symlink named "gst-inspect-1.0"), where it will be
autoloaded when needed.

test-gstreamer-completion.sh is (for now) in tests/misc -- it might be
worth creating "tests/check/tools", with all the necessary automake
boilerplate, and moving test-gstreamer-completion.sh there, and have it
run automatically with "make check".

IF YOU'RE NEW TO BASH COMPLETION SCRIPTS
----------------------------------------

"complete -F _gst_launch gst-launch-1.0" means that bash will run the
function "_gst_launch" to generate possible completions for the command
"gst-launch-1.0".

"_gst_launch" must return the possible completions in the array variable
COMPREPLY. (Note on bash syntax: "V=(a b c)" assigns three elements to
the array "V").

"compgen" prints a list of possible completions to standard output. Try
it:

    compgen -W "abc1 abc2 def" -- "a"
    compgen -f -- "/"

The last argument is the word currently being completed; compgen uses it
to filter out the non-matching completions. We put "--" first, in case
the word currently being completed starts with "-" or "--", so that it
isn't treated as a flag to compgen.

For the documentation of COMP_WORDS, COMP_CWORD, etc see
http://www.gnu.org/software/bash/manual/html_node/Bash-Variables.html#index-COMP_005fCWORD-180

See also:
* http://www.gnu.org/software/bash/manual/html_node/Programmable-Completion.html
* http://www.gnu.org/software/bash/manual/html_node/Programmable-Completion-Builtins.html

The bash-completion package provides the helper function
"_init_completion" which populates variables "cur", "prev", and "words".
See
http://anonscm.debian.org/gitweb/?p=bash-completion/bash-completion.git;a=blob;f=bash_completion;h=870811b4;hb=HEAD#l634

Note that by default, bash appends a space to the completed word. When
the completion is "property=" we don't want a trailing space; calling
"compopt -o nospace" modifies the currently-executing completion
accordingly. See
http://www.gnu.org/software/bash/manual/html_node/Programmable-Completion-Builtins.html#index-compopt

* tests/network-clock.scm: Commentary update.

* gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone.
Didn't really make sense, not implementable with basetransform,
etc.
(gst_identity_transform): Unref inbuf via make_writable. Feeble
attempt at implementing the sync property, needs an unlock method.

* gst/base/gstbasetransform.c (gst_base_transform_transform_caps):
New func, by default returns the same caps (the identity
transformation).
(gst_base_transform_getcaps): Uses transform_caps to return
something sensible.
(gst_base_transform_setcaps): Complicated logic to get caps on
both pads, even if they are different, and to call set_caps once
for every time both pads get their caps set.
(gst_base_transform_handle_buffer): Give the ref to the transform
function. Allows in-place modification of the buffer.

* gst/base/gstbasetransform.h (transform_caps): New class method.
Given caps on one side, what can I do on the other.
(set_caps): Take two caps, one for each side of the element.

* gst/gstpad.h:
* gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify
caps in place. This is safe because we can check the mutability of
the caps, and a good idea because fixate functions are just called
as a matter of last resort. (Not actually implemented.)
(gst_pad_set_caps): If the caps we're setting is actually the same
as the existing pad caps, just update the pointer without calling
setcaps. Assert that caps is either NULL or fixed, as per the
docs.

* gst/gstghostpad.c: Update for fixate changes.
