ad062e1879 audioecho: Don't do linear interpolation between samples
Linear interpolation adds quite some noise, and it's unlikely that
anybody will ever need sub-sample accurate delays. Proper resampling
before that will lead to better results.

c32bf052a0 audiofx/echo: added surround-delay and surround-mask
Add a new boolean surround-delay property that makes
audioecho just apply a delay to certain channels to create
a surround effect, rather than an echo on all
channels. This is useful when upmixing from stereo - for example.

Add a surround-mask property to control which channels
are considered surround sound channels when adding a
delay with surround-delay = true

1f32369451 Limit the delay by a new max-delay property
Introduce a new max-delay property that can only
be set before going to PLAYING or PAUSED. This
is used to limit the maximum delay and is set
to the current delay by default.

Using this will make sure that we have enough data
in our internal ringbuffer for the echo. With dynamic
reallocation of the ringbuffer as used before silence
could've been used as the echo directly after setting
a new delay.

a99d3f8769 Update and add documentation for plugins with no deps (gst).

fb8a2b359d Save some allocations if the echo delay is increased often
Save some allocations if the echo delay is increased often
during playback by always allocating enough memory to hold
data up to the next complete second, i.e. in the worst case
allocate memory for one additional second.

f2524f71d7 Add note that audioecho's reverb sounds metallic
Add a note to the docs that audioecho's reverb will
sound metallic. This happens because for a real
reverb filter additional filtering is necessary.

Also note which values should be used for the delay
property to get an echo effect.

99753365c6 Rename audioreverb to audioecho. Fixes bug #568395.
The element can add an echo and a simple reverb effect to
an audio stream but for a real reverb filter it would need
some additional filtering to prevent a metallic-sounding
result.
