We don't need sal/main.h in salinit.cxx as far as I can see.
Add stuff to sal/main.h so that we can link an iOS executable that
actually will run, and hack the makefile so that cppunittester builds
successfully.
Of course, a cppunittester executable built here won't be usable for
anything interesting as we don't build any dynamic libraries of
LibreOffice code for iOS, so there is nothing to pass on the command
line to load. But hey, baby steps, experimentation, doing work in the
public, commit often, etc...
- Old modifications were necessary for testshl2, which has simply been excluded
from the build for now.
- Tests in basebmp, basegfx, o3tl (that are executed during build) have been
converted from using modified CppUnit/testshl2 to using unmodified CppUnit.
- CppUnit's DllPlugInTester has problems with OOo tests on Windows, see
#i107562#, so for now a new cppunittester from sal is used instead.
