cmake: use cmake module to integrate liburing 1. WITH_LIBURING is used to set HAVE_LIBURING to decide use liburing in KernelDevice or not. 2. WITH_SYSTEM_LIBURING is to choose use system installed liburing or build the liburing from source code. Signed-off-by: Changcheng Liu <changcheng.liu@aliyun.com>

cmake: set advice.detachedHead=false when cloning liburing silence "detached HEAD" warning like: You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new-branch-name> Signed-off-by: Kefu Chai <kchai@redhat.com>

cmake: build liburing with -fPIC in liburing, https://github.com/axboe/liburing/commit/75cad68b953fe0fabbc4b1ced1ab4ba0ed5da18e partially reverts https://github.com/axboe/liburing/commit/4e360f71131918c36774f51688e5c65dea8d43f2, which builds liburing.a with -fPIC. so we need to pass -fPIC by ourselves. otherwise we'd have /usr/bin/ld: ../../liburing/src/liburing.a(setup.ol): relocation R_X86_64_PC32 against symbol `io_uring_queue_mmap' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status src/test/fio/CMakeFiles/fio_ceph_objectstore.dir/build.make:154: recipe for target 'lib/libfio_ceph_objectstore.so' failed Signed-off-by: Kefu Chai <kchai@redhat.com>
