137250239e Make sure CALLOUT_DFRMIGRATION is not used 
This flag supports the callout migration in FreeBSD.  This feature is
not supported by libbsd.

e37f03e47a Make sure CALLOUT_PROCESSED is not used 
This flag is only used in combination with the callout expire list,
which we do not use in libbsd.

6d9d7b1956 Critical bug fix for callouts 
FreeBSD has two callout executors, one in software and one in hardware
interrupt context.  In libbsd, all callouts are executed by the timer
server.  Entirely remove the different execution contexts for libbsd.
Previously, this was not properly done which could result an invalid
callout_drain() sequence leading to system memory corruption.

94b5368388 Avoid malloc() in getsockaddr() 
The getsockaddr() function is used to allocate a struct sockaddr of the
right length and initialize it with userspace provided data.  It is used
for the connect(), bind() and sendit() family functions.  In particular,
the sendit() function is used by the UDP send functions.  This means
each UDP send needs a malloc() and free() invocation.  This is a
performance problem in RTEMS (first-fit heap) and may lead to heap
fragmentation.  Replace the malloc() allocation with a stack allocation.
This requires SOCK_MAXADDRLEN (= 255) of additional stack space for
libbsd.

A further optimization would be to get rid of the stack copy of the
socket address.  However, this would require to check each consumer of
the address to ensure that it is not modified.

02373194fe Update due to Newlib 2017-06-07 changes 
The following files are now provided by Newlib:

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

The <sys/param.h> and <sys/cpuset.h> are now compatible enough to be
used directly.

Update #2833.

5e093a5bcb SLEEPQUEUE(9): Fix absolute timeouts 
The FreeBSD kernel timeouts are always based on the uptime.  Thus, we
have to use the relative watchdog.  C_ABSOLUTE just means that the
timeout value is already an uptime value.
