Marcio Barbosa 70e5c4f6a4 macos: delegate sock_* calls to bkg daemons
As part of Apple's ongoing effort to modernize macOS, improve security
and reliability, the deprecation of kernel extensions was officially
announced at WWDC19. According to this announcement, Kernel programming
interfaces will be deprecated as alternatives become available, and
future OS releases will no longer load kernel extensions that use
deprecated KPIs by default.

Unfortunately, the following KPIs, extensively used by rx, are included
in the list of deprecated KPIs as of macOS 10.15:

- sock_receivembuf
- sock_close
- sock_send
- sock_socket
- sock_setsockopt
- sock_bind

To workaround this problem, delegate calls to the functions mentioned
above to bkg daemons forked by afsd. Notice that the ifadd_* and ifnet_*
functions are also deprecated. Fortunately, these calls can be avoided
enabling AFS_USERSPACE_IP_ADDR.

Thanks to Andrew Deason for his assistance (ideas, suggestions,
documentation, etc).

AFS is a distributed file system that enables users to share and
access all of the files stored in a network of computers as easily as
they access the files stored on their local machines. The file system is
called distributed for this exact reason: files can reside on many
different machines, but are available to users on every machine.
