Trick's backtrace or attach functionality fails on systems like Ubuntu
where the use of ptrace(2) is restricted. Where it is defined, use the
PR_SET_PTRACER prctl with the argument PR_SET_PTRACER_ANY to allow any
process to attach.
Created a new executive job that waits for threads to finish and readies them
for their next frame of execution. Created a new job class system_thread_sync
after the top of frame jobs and before the input processor is run to sync the
threads. Along the way cleaned up instrumentation jobs on the threads to fix#290.
Changed Trick::Executive::get_current_version to return a const reference
to the string that holds the version. This avoids a copy of the string object
and avoids that object going out of scope. As a string, the debug_command
had the same problem so I fixed that one as well.

Added a test to set the debugger command to gdb or lldb depending
on availability. Created a new script for lldb to run. Modified
the script for gdb to backtrace all threads.

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.

Initial checkin of STL checkpointing. This checkin only covers the sequential
STLs, vector, list, deque, set, and multiset. This checkin does include the
changes in Trick header files to include/exclude our STLs properly to make a
restartable checkpoint.

Found two issues. First is that the next call times for
all of the jobs was not calculated correctly. Second is
that the if the user wants to sync the sim to a real time
clock interval, the initial sync to the real time clock was pausing
the full starting sim time instead of syncing to the clock
interval.

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.
