Fix a typo in autoplugging document

tutorials: basic: update gstreamer-tools.md

For the use of matroskademux plugin, the PAD template has changed to
video_%u and audio_%u which generate video_0 and audio_0, respectively.
So the current example using old pad names(video_00/audio_00) causes the
failure in linking pads. This patch changes the pad names into correct
ones.

tutorials: basic: fix typos

Fix typos in 'Basic tutorial 10: GStreamer tools' and
'Basic tutorial 12: Streaming' pages.

Fix opengl.md typo

Cerbero has moved from gnutls+openssl to only openssl

plugin-dev: fix broken anchor

update elements.md

basic-tutorial-3: Add audioresample

If the sink chosen by autoaudiosink doesn't do resampling internally,
the pipeline may fail. In this specific case, someone on Windows had
configured their sound card to 96000 instead of 48000 and the tutorial
was failing.

Thanks to Olivi55 from IRC for reporting.

basic-tutorial-3: Add audioresample

If whatever is in autoaudiosink doesn't do resampling, and 48000 isn't
its configured rate, the tutorial will fail.

https://gitlab.freedesktop.org/gstreamer/cerbero/merge_requests/356

design: first pass at some OpenGL design documentation

correctly when gst-docs is built on its own.

seeking: Add some info on instant-rate changes to the design docs

Describe how the instant-rate change events should work in the seeking design

installing/android: Use the correct NDK version, not latest

The toolchain is not ABI compatible between NDK versions, so people
should ideally use the same NDK that the binary releases were built
with.

app-dev/playback-components: add missing gst_clear_caps

gst-launch: document how to run a pipeline with a specific latency

I keep forgetting the exact syntax to do that so I figured I'd just
document it properly.

Also resync markdown code excerpts with the example's source code

Update theme

design: Fix typos in docs

Port gst_element_query*() functions over to the 1.0 API

We don't take the GstFormat as pointer anymore. This was already fixed
long ago in the actual code but not in the markdown documentation.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-docs/issues/44

Update index.md

Typo in boiler.md

Fix table layout in basics.md

Fix links in basics.md
