58be309344 multihandlesink: Fix buffers-queued being off by one
max_buffer_usage is the index of the oldest buffer in the queue,
starting at zero, not the number of buffers queued.

find_limits returns the index of the oldest buffer that satisfies the
limits in its min_idx parameter, not the number of buffers needed. Fix
this use too in order to keep passing the tests that read
buffers-queued.

8b9ebd8f88 multihandlesink: Update bufpos in a separate pass
If a client gets dropped and the iteration gets restarted, bufpos is
incremented again for all clients that preceded the dropped one, causing
havoc.

Adjust the bufpos for all clients first before trying to drop any.

5c4f4ac1bd Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.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.

8c4d3c6aa9 multisocketsink: handle client close correctly and EWOULDBLOCK
Fixes 100% cpu usage when client disconnects. Commit 6db2ee56
would just make multisocketsink ignore reads of 0 bytes without
removing the client, so we'd get woken up over and over again
for the client.

Fix the original issue differently by handling the non-fatal error code.

of a pointer is larger than the size of an integer, It would also

37aa31379f tcp: don't use soon-to-be-deprecated g_cancellable_reset()
From the API documentation: "Note that it is generally not
a good idea to reuse an existing cancellable for more
operations after it has been cancelled once, as this
function might tempt you to do. The recommended practice
is to drop the reference to a cancellable after cancelling
it, and let it die with the outstanding async operations.
You should create a fresh cancellable for further async
operations."

6db2ee56b6 tcpserversink: don't error out if clients send us something, just ignore it
We don't expect clients to send us any data, but if they do, just
ignore it. Web browsers might send us an HTTP request for example,
but some will still be happy if we just send them data without
a proper HTTP response.

There was a bug in the reading code path. We only have a small
read buffer and would provoke an EWOULDBLOCK trying to read
because we don't bail out of the loop early enough.

8328eab2de socketsrc: Add support for GstNetControlMessageMeta
multisocketsink now understands the new GstNetControlMessageMeta to allow
sending control messages (ancillary data) with data when writing to Unix
domain sockets.

Thanks to glib's `GSocketControlMessage` abstraction the code introduced
in this commit is entirely portable and doesn't introduce and additional
dependencies or conditionally compiled code, even if it is unlikely to be
of much use on non-UNIX systems.

e63e023e30 multisocketsink: Add support for GstNetControlMessageMeta
multisocketsink now understands the new GstNetControlMessageMeta to allow
sending control messages (ancillary data) with data when writing to Unix
domain sockets.

A later commit will introduce a new socketsrc element which will similarly
understand `GstNetControlMessageMeta`.  This, when used with a
`GSocketControlMessage` of type `GUnixFDMessage` will allow GStreamer to
send and receive file-descriptions in ancillary data, the first step to
using memfds to implement zero-copy video IPC.

Thanks to glib's `GSocketControlMessage` abstraction the code introduced
in this commit is entirely portable and doesn't introduce and additional
dependencies or conditionally compiled code, even if it is unlikely to be
of much use on non-UNIX systems.

a297b0545f socketsrc: Add connection-closed-by-peer signal
This provides notification that the socket in use was closed by the peer
and gives an opportunity to replace it with a new one which is not
closed, allowing reading from many sockets in order.

I use this in pulsevideo to implement reconnection logic to handle the
pulsevideo service dieing, such that is can be restarted without
disrupting downstream.

0c054aa00d socketsrc: Refactor to simplify
* Don't bother polling, just do a blocking read, the `GCancellable` will
  take care of unlocking.  This should also be faster on MS Windows where
  the GIO documentation for `g_socket_get_available_bytes` states: "Note
  that on Windows, this function is rather inefficient in the UDP case".

* Implement `GstPushSrc.fill` rather than `GstPushSrc.create`.  This means
  that we will be using the downstream allocator which may be more
  efficient.  It also means that socketsrc is likely to respect its
  "blocksize" property (assuming that there is enough data available).

7c10499ecd tcp: Add element socketsrc
`socketsrc` can be considered a source counterpart to `multisocketsink`.
It can be considered a generalization of `tcpclientsrc` and
`tcpserversrc`:  it contains all the logic required to communicate over
the socket but none of the logic for creating the sockets/establishing
the connection in the first place, allowing the user to accomplish this
externally in whatever manner they wish making it applicable to other
types of sockets besides TCP.

This commit essentially copies the implementation directly from
tcpserversrc.  Later patches will tidy the implementation up and
re-implement `tcpclientsrc` and `tcpserversrc` in terms of `socketsrc`.

b8232a7467 multisocketsink: Map GstMemorys individually when sending
If a buffer is made up of non-contiguous `GstMemory`s `gst_buffer_map`
has to copy all the data into a new `GstMemory` which is contiguous.  By
mapping all the `GstMemory`s individually and then using scatter-gather
IO we avoid this situation.

This is a preparatory step for adding support to multisocketsink for
sending file descriptors, where a GstBuffer may be made up of several
`GstMemory`s, some of which are backed by a memfd or file, but I think this
patch is valid and useful on its own.
