Make 'extmap' attributes another type of OTHER attribute, which are
printed verbatim, but instead of skipping over them when parsing them
and "strip extmap" is requested, always parse and store them and then
skip over them when printing them.

All OTHER attributes are printed verbatim as strings, but we still want
to be able to distinguish between different types of them. Introduce an
extra enum for that purpose.

Even though both true and false are set in different calls to the
function, there's no effective difference in output.

Make sure sdp_attributes is only used for _received_ SDP attributes, and
not ones that we want to send out. The only places where self-generated
attributes are being used is the T.38 gateway.

Use a settable callback function to do attribute printing. This makes it
possible to use different sources for SDP attribute output in different
situations.

Create a separate smaller struct that contains only the relevant pieces
of the attribute string. Embed this into the larger `sdp_attribute`
struct, which also contains all the parsed-out information, which is
needed only during initial processing.
Functional no-op.

Fix up tests to match reordered attributes.
Remove 10-year-old a=ssrc parsing code completely as it's unused.

For tagged attributes using a `a=name:tag value` format, extend pattern
matching so that just `name` matches as well as `name:tag`. Only support
this for removal (not substitution) as these attributes generally can
appear multiple times, and doing a static substitution on all of them is
kinda pointless.

As we don't directly append to an existing GString any more anyway,
simplify the function signature by just returning a new GString if the
format string is known.

For attributes that have a value, consider both the full attribute
string `a=name:value` and just the attribute name itself `a=name` when
checking for removal and substitution instructions.

With attributes names separated from their values, we can implicitly add
the separator ':' instead of having to include it in the attribute name.

Where the attribute name is known, only pass the name itself as "name"
and pass the rest as "value" for clearer indication of what is what.

We're in control of all the source strings, so we can just mandate not to
include the leading a= in the string.

gcc <12 propagates the const-ness of the given value to the newly
declared variable with __auto_type, leading to silly "can't assign to
const variable" errors. Work around this with an ugly macro.
