8cf858fb27 uridownloader: add new gst_uri_downloader_set_parent
If set, the parent is used to proxy need-context messages from
uridownloader's http source in order to get cookies/headers
from the pipeline.

42af2d66d8 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.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.

429353337d uridownloader: Take the ownership of the src element
The URI downloader is creating the source element with
gst_element_factory_make() that returns a floating reference that nobody
is consuming. This is causing problems in WebKit, where the smart
pointers used to take references of the source elment get confused and
end up consuming the floating reference and then releasing the element,
which usually crashes because the URI downloader still tries to use its
src element. See https://bugs.webkit.org/show_bug.cgi?id=144040.
This commit adds two helper functions to ensure and destroy the source
element, to make the code simpler and less error prone. The ensure
method takes care of checking if we can reuse the existing one or we
need to create a new one, taking always its ownership. The destroy
method simply avoids duplicated code to set the source to NULL state and
then unref it.

93edd99bf7 dashdemux: add support for HTTP HEAD method of time sync
The urn:mpeg:dash:utc:http-head:2014 method of time synchronisation
uses an HTTP HEAD request to a specified URL and then parses the
Date: HTTP response header.

This commit adds support to dashdemux for this method of time
synchronisation by making a HEAD request and then parsing the Date:
response.

This commit adds support to gstfragment to return the HTTP headers
and to uridownloader to support HEAD requests. To avoid creating a
new API, the RANGE get function is re-used (abused?) with start=-1
and end=-1 to indicate a HEAD request.

5a5f6d1b7a uridownloader: fix deadlock near EOS
A deadlock can happen when the source sends EOS when
being put to NULL as the object lock is being held by the
thread that sets the element to NULL and is needed by
the event handler.

9e313eb0a7 uridownloader: do not set cancelled unless explicitly called by user
Cancelled is a 'permanent' state of the uridownloader and is only
removed by a call to _reset. When a download fails we just want to
return NULL on the fetch function and leave the downloader ready
for another fetch, otherwise the user has to call _reset after
failed downloader, even when it didn't call _cancel.

e76f3e95fd uridownloader: add support for range based downloads
Adds a new API gst_uri_downloader_fetch_uri_with_range that allows
downloading only a byte range from an URI. It uses a seek event

f72869816c uridownloader: make cancelled state 'permanent' until a reset
When downloading and cancelling quickly the uridownloader object and the
element using it could miss the cancelled window and the uridownloader
would fetch the wrong URI and block on subsequent fetches.

This was also problematic when stopping elements, while one task would
call the cancel, another element thread could issue a new fetch_uri. As
the cancel state isn't 'permanent' this fetch_uri would block and
prevent the whole element from stopping and going to NULL.

This patch makes the 'cancelled' state permanent until a
gst_uri_downloader_reset is called. This way the element knows the
window where the uridownloader isn't active and only reactivate it when
ready.
