o changed name, OSD_ATOMIC_INLINE to EPICS_ATOMIC_INLINE
o changed supported data types, unsigned removed and int added (per reveiw at codeathon)
o added add/subtract functions (per reveiw at codeathon)
o now presuming that __sync_synchronize available all gcc 4 mingw does not provide windows mem barrier)
o consolodated on one implemention for Microsoft invarient of cmplr intrinisic or win32 by using macros to config a shared header file
o improved doc in epicsAtomic.h
o added overloaded c++ interface in namespace epics :: atomic to epicsAtomic.h
o added epicsAtomicReadMemoryBarrier and epicsAtomicWriteMemoryBarrier interface to epicsAtomic.h
o changed the implementation so that each of the functions can be individually specified for a particular compiler, os, or in the generic implementation (this is accomplished with macros)
o modified the functional and performance test so that they are based on templates so we can easily support new data types
o modified performance tests to repeat function calls and measure performance using a template
The old test for discriminating between statically and dynamically
linked applications (os/RTEMS/osdTime.cpp:staticTimeRegister()) is
wrong, it never detects a dynamically loaded app.

modified:
src/libCom/osi/os/RTEMS/osdTime.cpp
Refactored logClientSend in libCom/logClient/logClient.c; took the code between the mutex operations and
moved it to a private method - sendLogMessageinChunks. Call this method once for the prefix (if it exists) and once
for the actual message.
Added ioCsh registration code into src/libCom/iocsh/libComRegister.c registering a command called
"iocLogPrefix" that sets this prefix.
Unit tested with and without prefixes.
Performance tested with and without prefixes - without prefix is approx the same. With prefix is about
twice the time (reflecting the two calls to sendLogMessageinChunks I think)
CA links in records were being removed without locking them first.
We also now set the link type to CONSTANT, which prevents some
assertion failures if the record gets processed again before the
IOC finally dies.
o refactored compilerDependencies.h into code that is compiler specific (one libCom/osi/compiler/xxx/compilerDependent.h for each comiler) and code that isnt libCom/osi/compilerDependencies.h (this is a new location and is no longer in libCom/misc).
