Particularly the C++ files generated for the rather comprehensive
3GPP asn.1 specified protocols like MAP, RANAP, ... result in very
large source files and subsequently g++ processes that consume well
into the multiple gigabyte range of memory.
Let's use the '-U 5' option to ask the ttcn3_compiler to split all
c++ files into 5 chunks, resulting in more files to compile, but
smaller individual files.
I also tested '-U type' before, but it was still grinding my 16GB RAM
laptop to unusable deep-swapping state when running 'make -j8' for
the IuCS extended MSC test suite.

Newer eclipse-titan makefilegen already sets CPPFLAGS like this:
CPPFLAGS = -D$(PLATFORM) -I$(TTCN3_DIR)/include$(TTCN3_SUBDIR)
where TTCN3_SUBDIR expands to '/titan' and TTCN3_DIR to '/usr'
If we add /titan after include we end up with
-I/usr/include/titan/titan/ which will cause the compile to fail due to
a missing TTCN3.hh include.
Check the titan version so we retain backwards compatibility.

There seems to be no option for ttcn3_makefilegen to disable generated
code warnings so the only way to clear output from useless warnings
about indentation and such is to manually strip -Wall using sed.

This makes it easier to track when this workaround can be disabled once
Debian/upstream (hopefully) resolve the issue.

By default, if ccache is found in PATH when regen-makefile.sh runs,
use cached compiled C++ object files during the build (or populate
the cache in case an object is not cached yet). Objects are cached
in ccache's default cache directory (~/.ccache) unless overriden by
the CCACHE_DIR environment variable.
The USE_CCACHE environment variable overrides auto-detection
in regen-makefile.sh and disables (USE_CCACHE=0) or enables
(USE_CCACHE=1) use of ccache.
Rebuilding the test suite from scratch with a populated cache
is an order of magnitude faster than doing an initial build.
ccache only speeds up C++ (.cc) to object file (.o) compilation.
Linking object (.o) files into shared object (.so) files is still
performed by the real compiler during every build.

Let's use the preprocessor to avoid IPA_Emulation pulling *all*
dependencies into each and any of our projects. The code readability
suffers a bit from the many #ifdefs, but compilation speed increases
if we don't have to pull in all those (recursive) dependencies.
After all, a BTS test case will never need SCCP, GSUP or MGCP.

By default the build fails on Debian due to gcc version check in
/usr/include/titan/cversion.h - instead of asking users to manually
change this file let's add workaround to our makefile fixer which
disables this check automatically.
