Some fixes to make pas2c+clang compile all engine files

stack-protector flag needs to be passed to the linker as well

Allow building with modern 'base' package

port all Q_WS_* to Q_OS_* so that we are forward compatible with Qt5

lua warning with clang

These could be handy

update with default

set linker flags where appropriate

this was getting annoying, don't error out on warnings physfs

ok. this could be tidier, but, I'm sick of hogs w/ unmodified thaw thawing on exactly wrong turn.

make sure that also CXX sources pick up the flags (although I'm not 100% of the correctness of the tests)

add fstack-protector and fvisibility=hidden to cmake tests

also apply linker flags to haskell programs

add relro linker tests (issue #663)

move compiler checks in a separate cmake module

simplify cmake message syntax a little bit

move platform specific and revision info code into separate cmake modules
