New members are added to the network interface
-getaddrinfo
-getaddrinfo_async
gethostbyname is unchanged but gethostbyname_async result param now contains results od DNS records found.
Test cases for sync/async added added to DNS test folder.
In this test case if asynchronous DNS request results does not happen
in requested time, the request must be cancelled to ensure it does not
happen later on when test has exited already.
We've seen couple of crashes in CI tests which indicate this kind of behaviour
but this is very difficult to reproduce.
Deprecate wait() in favour of acquire(), try_acquire(),
try_acquire_for() and try_acquire_until().
Brings Semaphore more into line with CMSIS-RTOS 2 (which uses "acquire"),
itself (as it has "release"), and other classes having "try", "try for"
and "try until".
Also steps away from vague "wait" term - the primary operation here is
to acquire the semaphore, and this will of course sleep.
Added smarter rounding of times in recv_timeout and increased the delta by one, to allow "off-by-one" errors.
Reverted commit 88eea6a, reducing TESTS_TIMEOUT back to 480.
Introduced a 100ms timeout for waiting on asynchronous DNS resolution.
Improved error handling on disconnects.
