* 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)
o added CMPLR_SRC_DIRS to ALL_SRC_DIRS, and added compiler/$CMPLR_CLASS) to INSTALL_INCLUDES in CONFIG_COMMON
o added additional compiler specific rule deciding where things are installed to in CONFIG_COMMON
o added compiler specific include install to RULES_BUILD
o changed configure/os/CONFIG.linux-x86.linux-x86 to specify minimum arch is 586 (pentium circa 1995)
o changed configure/os/CONFIG.win32-x86-cygwin.win32-x86-cygwin to specify minimum arch is 586 (pentium circa 1995)
o added epicsAtoimic facility to libCom/Makefile
o added testing and performance measurement to libCom/test/Makefile
