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.

c7e162abd8 mmc: Optimize mmc_wait_for_req() 
Use a self-contained RTEMS binary semaphore instead of msleep() and
wakeup().  This is itself more efficient and in addition allows the use
of mmc_wakeup() in interrupt context.
