Our joint conclusion was that wrapping system includes with
extern "C" used to be necessary on some OS builds when C++
was much less common, but is now wrong.
o fixed issue introduced by last revision where definition of lock functions and lock key were not present if its sunos 5.10 or greater
(its time consuming to develop code if you can only run the (SUNPRO) compiler indirectly)
o dont include epicsAtomicOSD.h from any of the implementations of epicsAtomicCD.h unless the compiler has support for an inline keyword
o removed superfluous ifdef on EPICS_ATOMIC_INLINE all versions of epicsAtomicDefault.h and epicsAtomicOSD.h
o In the implementations of epicsAtomicOSD.cpp if EPICS_ATOMIC_INLINE isnt defined define it to be empty and then include epicsAtomicOSD.h
o fixing some compile time issues for solaris version of epicsAtomicOSD.h (so that Janet can run another compile on that os)
* fix libCom exports for things which used to be built differently
* logserver needs winsock
* errlog prefix: fix warnings on win32
* fix dll imports in ioc/db
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)
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).
o removed function
epicsAtomicTestAndSetUIntT
o added new functions
epicsAtomicSetPtrT
epicsAtomicGetPtrT
epicsAtomicCmpAndSwapUIntT
epicsAtomicCmpAndSwapPtrT
o changed msvc intrinsics to define memory fence
o fixed mutex synchronized version so that its slow, but correct if the c++ compiler doesnt synchronized local scope static initialization
o changed most of the set/get methods to use memory barriers instead of some other primitive
o added additional tests
o removed -march=i586 from CONFIG.linux-x86.linux-x86
o fixed compile errors in epicsAtomicOSD.h (I didnt have the proper version of solaris for initial testing here)
