* work around some c++11 issues
* fix some literals in rbbitst.cpp
* update escaper
* add mh-aix-va for using escaping
* work around nullptr and uchar16 issues
* revert bad icuinfo.cpp checkin
this commit still fails.

* create a new escaper tool - needs to be invoked in mh- files
* escapes to temporary _whatever.cpp files
* does NOT handle multi line u"xxx" (or u'xxx'? )
* does not cleanup _*.cpp files
* fixup a bunch of Makefiles to add -I$(srcdir) (doesn't hurt anyway)
