fb4601734f Need to include SimTime.hh for ICG and swig processing.
Added the sim time header files to files_to_ICG.hh and sim_services.i so it will be processed.

a95e8e086b Use udunits package for units conversions
Copied the units_conv.c from 15 that includes the new units to master.

Swept through the code removing includes to Unit.hh and UCF.h where they
are no longer needed.  Remade makefile dependencies.

684f0e6bdc Use udunits package for units conversions
Initial checkin of using udunits for measurement units conversions.  Replaced
our conversion code in ICG and swig code to use udunits.

Also added code to convert unit symbols that we used in Trick that are different
names in udunits.

Added a sim_object that will eventually allow users to specify a custom
set of files to read units information.

8354546160 HDF5 data recording broken
Overrode the write_data routine for HDF5 recording.  The new routine writes
out all buffered values of an individual variable with one or two HDF5 calls.
This is much more efficient than before where we were making an HDF5 call
for a single value.

8c3e322ed1 Variable server restart issues
Added mutexes in the variable server listener thread and each variable server thread.
During checkpoint restart all of these mutexes are locked by the master thread to
stop accepting new connections and stop all read/writing to all variable server clients.
Communication is resumed after the checkpoint has been reloaded.

03d6105c6c Remove catches for non-Trick exceptions
Removed the catches for std:exceptions and unknown exceptions.  The best way
I found to provide a clue to where the exception comes from is to allow the
handler for unhandled exceptions execute.  This is std::terminate which calls
abort and trips a SIGABRT.  I added a signal handler for SIGABRT which like
SIGSEGV, we can print a stack trace or attach a debugger to the process before
exiting.  The stack trace print is on by default.  By default the signal
handler is on, stack trace is on, debugger is off.

f63f44d876 Ignore privacy
Changed the storage of offsets from bytes to bits to better handle bitfields.
Added code to track classes that are defined within other classes and are
private/protected.  These classes cannot be used in templates because our
io_src code declares variables outside of the class that would try and use
these private/protected variables.  When a template is found to use a
private/protected class it is skipped.

fb7432d096 Add direct STL checkpointing
Modified ICG to save the non-canonical name for STLs.  This is typically more readable
because it is shorter.  Added code to the variable server to filter out requests accessing
STLs, because those accesses will not currently work.

bb6d7f0632 Math with temperature values is not as expected.
For addition and subtraction,  we created a new routine that
only scales second units to the first.  We apply it to all
conversions when adding and subtracting, but it only changes
the temperature results, because that is the only units that
has a bias factor. The comparision conversion routines were not
changed.

903ff05960 data record buffering optimizations
Added a loop to set each 1024th byte in the recording array to 1 once the
memory has been allocated.  Need to test if this is good enough to get Linux
to allocate the memory.

Added a current recording buffer pointer to use instead of using array offsets.
This should be more cpu cache efficient.

Changed the memcpy calls to direct casted integer assignments based on the size of the
parameter.  If the parameter is not size 1,2,4,or 8 we fall back to a memcpy.

57c76041f5 Get the value of a variable not parsed by SWIG in python
Wrote a python routine called get_value_by_ref_name that takes
a variable name string as an argument.  The string is passed to
ref_attributes to find the address and returns a REF2 structure.  The REF2
structure is passed to ref_to_value and the type and value of the variable
is returned in a structure.  We call vval_<type> to extract the raw value
from the structure and return that to python space.

Made a couple of other bug fixes in the FieldVisior and cpp input file
example found while investigating this issue.

941eb5c1cc Remove duplicate stand-alone libraries
I changed trick comm so that there is only one version built, not a slightly different version
if you are in or out of a sim.  While I was in the trick comm code, I removed all of the
unnecessary system header file inclusions out of tc.h.   I modified each of the source files
to include the system files it requires.  Some sim_services files were including tc.h and
also had to be edited to add headers.  I removed the stand-alone makefiles out of all
of the trick_utils directories.  Finally I modified the master makefile to exclude the
trick_util directories comm, math, and units from being archived into libtrick.a.  Each of
those directories will create their own library and will be included when linking a Trick sim.

19025d77ad Standardize directory names
Reorganized.  Created a new top level include directory that will hold all of Trick's header files. Moved all of the Trick headers to this directory.  Created a libexec directory that holds all of the executables that users don't need to execute directly.  Changed all of the executables remaining in bin to start with "trick-".  In the sim_services directories changed all source files to find the Trick headers in their new location.  Since all of the include files are gone in sim_services, removed the src directories as well, moving all of the source files up a level.  Moved the makefiles, docs, man, and other architecture independent files into a top level share directory.  Renamed lib_${TRICK_HOST_CPU} to lib64 or lib depending on the platform we're currently on.
