aws_socket_get_bound_address()

[graebm]

Now, if a user binds to port 0, they can query afterwards and see which port was assigned by the OS.

Issue #: #488

Adapted from: #487

Description of changes:

• NEW: int aws_socket_get_bound_address(const struct aws_socket *socket, struct aws_socket_endpoint *out_address)
• The socket stores this address during aws_socket_bind() call, which avoids threading issues during the aws_socket_get_bound_address() call.
• Windows-specific:
  • Simplified some error-handling paths in Windows socket code, which fixed some subtle bugs.
  • Fixed some bugs involving structs that weren't zeroed out before use.
