55ec47f555 vorbisdec: Initialize decoder directly once we have the 3 headers 
... instead of waiting for the first non-header buffer.

Also drop non-identification headers arriving after initialization or
before the identification header. We don't do anything with them and
they would just accumulate.

0619168e2a vorbisdec: Always handle in-band header packets once the first non-header packet arrives 
And clean up any old pending headers if we receive a new identification
header, or if we receive a new set of headers via caps.

Otherwise it might happen that we receive one or more header but not
all, and then afterwards all headers again, and libvorbis does not like
getting headers passed multiple times and would error out.

It only makes sense to pass the very latest headers to the decoder at
the time we can actually make use of them.

aab5cccc34 vorbisdec: Improve "new headers while initialized" handling 
If new headers arrive after we are initialized, we need to make
sure that they are indeed valid.

A vorbis bitstream always begins with three header packets and must
be in order.

Also some streams have unframed (invalid?) headers that might
confuse and disrupt the decoding process.

Therefore if ever we see new headers, we accumulate them and once
we get a non-header packet we check them to make sure that:
* We have at least 3 headers
* They are the expected ones (identification, comments and setup)
* They are in order
* Any other "header" is ignored

If those conditions are met, we reset and reconfigure the decoder

e575be6dc6 vorbisdec: Reset decoder in more situations 
This is a followup commit to b95725c37e

* Resetting the decoder should only happen when we get a new initialization
header (0x01) and not on the other headers
* The initialized variable only gets set to TRUE once all headers have
been parsed. Also check if the vorbis_info struct has been properly resetted
also. Failure to do that would cause vorbisdec to error if it got
two initialization header in a row (the first would configure the underlying
library and the second one would error out because it's already initialized)

90eb93c2ef Don't compare booleans for equality to TRUE and FALSE 
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs 
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

87bb5dddb2 Fix wrong access to undefined struct member 
For the USE_TREMOLO case, GstVorbisDec doesn't have
a vb member. Besides, Tremolo's vorbis_dsp_synthesis()
expects a vorbis_dsp_state to be passed as first
argument. Not a vorbis_block.
