cmake/configure.ac: Enable -fstack-protector-strong by default
This commit contains the following changes:
- Drops -fstack-protector in favor of -fstack-protector-strong.
Consequently, the ssp-buffer-size parameter has been removed as
-fstack-protector-strong ignores array size.
- Add new global opt-out for stack smash protection. This is enabled
by default for both autotools and CMake builds. Users can opt out
of stack smash protection by passing -DWITH_STACK_PROTECTOR=OFF to
CMake or --disable-stack-smash-protection when running ./configure.
- Renames HAVE_SSP_FLAG to HAVE_STACK_PROTECTOR_FLAG in
CMakeLists.txt to be more readable.
