That way it is not a global object anymore and is not attached to the
.init section and init array. If the function which contain the object is
not called then the serial object will not be present in the final binary.
Fix the following linker errors:

- Corrected handling, before errors would forcibly restart the
accept loop without checks for timeouts
- Rearranged accept logic to match the logic of
recv/send/recvfrom/sendto
User feedback indicated that the previous deprecation notices
were confusing and mislead migration from the old style of thread
spawning.
The deprecation notices were updated to emphasize the replacement
functions, and examples of correct usage were added in the doxygen.
One limitation of C++ is that implicit casts do not occur when
matching template overloads, as a consequence the callback's
argument type requires a strict match.
Unfortunately, the prevents the previously common pattern of using
void pointers as function arguments, causing unnecessary problems
for users porting code.
Thing *t;
void doit(void *p) { blablabla }
Callback<void()> cb(t, doit);
To avoid this, explicit overloads on void pointers were added. This
avoids a template expansion, and allows the implicit cast to occur
as the user would expect.
To avoid complications with unexpected IP versions, the wanted
IP version was added as an extra argument to DNS query functions
(defaults to NSAPI_IPv4).
Internal API changes:
m nsapi_dns_query
m nsapi_dns_query_multiple
Interestingly, though multiple questions can be encoded in a single
DNS packet, few, if any, nameservers respect any but the first
question. This makes support for coelescing DNS queries useless.
Internal API changes:
+ nsapi_dns_query_multiple
Note, dns_query_multiple takes a buffer of nsapi_addr_t to fill. This is
less dynamic than the linked-list method used in linux's gethostbyname,
but is easier to manage and more constrained.
Internal API changes:
dnsQuery -> nsapi_dns_query
Additionally restructured query code to emit/parse network structures
in stream form to hopefully document the underlying structure more
explicitly.
