The internal-iovec bencode semantics are not used any more. Remove the
relevant code.

These functions can return negative values to signal errors, therefore
use ssize_t as appropriate type.

Some invocations of ssrc_ctx_put() are deliberately passed a memory
reference, which produces an undesired compiler warning. Use an
intermediate variable to suppress it.

When the compiler does not have support for the __error__ attribute,
fallback to use the GCC posion pragma, which works on both gcc and
clang. It ha the advantage of being more portable and working at the
preprocessor level, which means is not affected by symbol redirection
due to builtin conversion or stack-protector remapping, at the cost of
worse diagnostics.

The function argument where the cast is applied is volatile void *,
use the same type on the cast.

Convert ssrc_ctx_put() and ssrc_ctx_hold() to macros to aide in
debugging reference leaks. Having them as inline functions hides the
actual location of the refcount changes.

Obsolete ssrc_ctx_get() as returning values from macros is awkward and
it was only used in two locations.

Also fix a function invocation mishap: obj_get_o() should be used
instead of __obj_get() as the latter is an internal macro.

Change-Id: Icc0d63f04b3816632fd120c1c749cafabbbfa331

This makes the type in line with string(3) functions and eliminates some
compiler warnings.

Also update the related bencode data type.

If we receive an SDP with a DTLS fingerprint, by default we adopt the
hash function used for that fingerprint in subsequent communication with
that peer. However, if the SDP is an answer, and we previously used a
different hash function in the offer towards that peer, then a later
re-invite offer would be sent with a different fingerprint, causing an
unexpected DTLS restart. Instead, make sure we don't change fingerprints
if one was already sent.

While these usages are not supposed to be security sensitive, it's still
best to avoid the usage altogether so that we do not need to think about
it. Add a taint macro so that this does not regress in the future.
