Changed some order only dependencies to actual dependencies. Added a
check in make_makefile_src for new files that should trigger recreating
Makefile_src.
CURDIR is used to produce absolute paths in S_source.d, which allows it
to be included from external makefiles. It is specifically intended to
be included from a Trickified project's user-facing makefile. That is,
the one the user is intended to include in a sim's S_overrides.mk. This
allows the project to automatically build their Trickified object as
part of a simulation build, but only when necessary as specified by the
dependencies.

Trick uses dlsym to dynamically load symbols at run time. At link time,
it cannot be known which symbols will be needed. When presented with a
library, the linker will only link in symbols that are known to be
needed. Therefore, the use of -whole-archive (Linux) or -force_load
(Mac) is necessary when linking a Trickified library into a sim.
We can simplify this by partially linking into an object instead of
creating a library. The linker will link all symbols in an object
regardless of whether or not they are known to be needed.

Moved makefile assignment of S_MAIN out of MAkefile.common to simulation
makefile. The definition in Makefile.common was causing trouble for
autotesting because it changes TRICK_HOST_CPU.
A different approach. Instead of trying to limit the number of times
S_overrides.mk is included, combine the makefiles so only one
call to make is made.
We've agreed that the long-term solution is to refactor the makefiles so
we don't use recursive make. Until then, continue double including
S_overrides.mk so that the $(S_MAIN) target is available in
S_overrides.mk. Resolve#360 by having Trickified libraries use
target-specific variables (ironically, on $(S_MAIN)) to avoid
duplication of the -whole-archive option.
Add the ability to register callbacks for errors that occur on the
asynchronous variable sampling thread. Implement __del__ and call
close in case the user forgot. Join the asynchronous sampling thread
in close before returning.

Namespace packages are a mechanism for splitting a single Python
package across multiple directories on disk. With the addition of
$(TRICK_HOME)/pymods/trick, there now exists a package named 'trick' at
$(TRICK_HOME)/pymods and in each SIM_* directory. This change allows sims
to import modules from both locations.

The input file that is created while running monte carlo runs is done
in 3 different places. There was no easy way to collect all of those
lines in one place, so I duplicated the lines in the dryrun function.
Created a hook for the clang preprocessor. The hook does 2 things. It
keeps track to which header files we have entered and exited. Second it
searches for the use of TRICK_ICG. If we find an instance of TRICK_ICG we
mark all of the included files from this point up the chain as requiring
compensation. To compensate for using TRICK_ICG we write out the older
offset statements to get the location of variables in classes/structures.
Like other TRICK_SYSTEM variables, users should not modify this.
This renders TRICK_LDFLAGS and TRICK_USER_LINK_LIBS redundant. While we
would like to eventually remove TRICK_USER_LINK_LIBS, it's not likely to
ever actually happen.

For the record, I'd like to point out that many of the DataRecordGroup
functions shouldn't be called after init, but we don't prevent anyone
from doing so. Bad Trick!

One of the constructor parameters enables automatic creation of
SI-prefixed versions of the root unit, which obviates the need to
create them individually.
