unify handling of library prefixes and extensions

make sure that all specs define QMAKE_{PREFIX,EXTENSION}_{SH,STATIC}LIB,
and adjust the code to make halfways consistent use of these variables,
in particular on windows; Win32MakefileGenerator::getLibTarget() is gone
as a result, as is QMAKE_CYGWIN_SHLIB. still, tons of hardcoded "lib"
references remain in the unix generator, because no-one cares.
