Add some POSIX header files for RTEMS 

Add the POSIX header files

  * arpa/inet.h
  * net/if.h
  * netdb.h
  * netinet/in.h
  * netinet/tcp.h
  * sys/socket.h
  * sys/syslog.h
  * sys/uio.h
  * sys/un.h
  * syslog.h
  * termios.h

and their dependencies for RTEMS.  The origin of these files is the
latest FreeBSD.

* Interface flags are of two types: network stack owned flags, and driver

* broken out such that the network stack is responsible for synchronizing
* the stack-owned fields, and the device driver the device-owned fields.
* Both halves can perform lockless reads of the other half's field, subject
* to accepting the involved races.
*
* Both sets of flags come from the same number space, and should not be

* field.
*
* The following symbols identify read and write requirements for fields:
*
* (i) if_flags field set by device driver before attach, read-only there
* after.
* (n) if_flags field written only by the network stack, read by either the

* Local port number conventions:
*
* When a user does a bind(2) or connect(2) with a port number of zero,
* a non-conflicting local port address is chosen.
* The default range is IPPORT_HIFIRSTAUTO through
* IPPORT_HILASTAUTO, although that is settable by sysctl.
*
* A user may set the IPPROTO_IP option IP_PORTRANGE to change this
* default assignment range.
*
* The value IP_PORTRANGE_DEFAULT causes the default behavior.
*
* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
* into the "high" range. These are reserved for client outbound connections
* which do not want to be filtered by any firewalls.
*
* The value IP_PORTRANGE_LOW changes the range to the "low" are
* that is (by convention) restricted to privileged processes. This
* convention is based on "vouchsafe" principles only. It is only secure
* if you trust the remote host to restrict these ports.
*
* The default range of ports and the high range can be changed by
* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
*
* Changing those values has bad security implications if you are
* using a stateless firewall that is allowing packets outside of that
* range in order to allow transparent outgoing connections.
*
* Such a firewall configuration will generally depend on the use of these
* default values. If you change them, you may find your Security
* Administrator looking for you with a heavy object.
*
* For a slightly more orthodox text view on this:
*
* ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
*
* port numbers are divided into three ranges:
*
* 0 - 1023 Well Known Ports
* 1024 - 49151 Registered Ports
* 49152 - 65535 Dynamic and/or Private Ports
