channel_map is applied between in and postin.
Without this test, if the input format is an acceptable internal format,
the in->postin conversion is skipped. In the best case,
it ignores channel_map, in the worst case it causes an assert failure
if the number of channels is changed by the map.

Even if linking directly to getaddrinfo, use our version of
gai_strerror instead of the system's version. Microsoft explicitly
documents that their version of gai_strerror is thread-unsafe.
Signed-off-by: Martin Storsjö <martin@martin.st>

This avoids warnings if there already exists a definition.

This is the case on windows, where the getaddrinfo isn't available
and linked to (and we use our fallbacks instead, which actually
try to use the proper getaddrinfo version if found at runtime),
but gai_strerror still exists as a define.
Signed-off-by: Martin Storsjö <martin@martin.st>

This is useful if a proper getaddrinfo is loaded dynamically on
windows, while using the fallback implementation of gai_strerror.
