If we introduce atomic, then I prefer that we use the c11 standard stuff for
that.
This means update the top level cmake lists file to use -std=c11 instead of
-std=gnu99 and
use the function in <stdatomic.h> instead of gcc builtins.
Something like:
```C
//bundle_private.h
...
#include <sdtatomic.h>
...
struct celix_bundle {
bundle_context_pt context;
char *symbolicName; //for debug
struct celix_bundle_activator *activator;
_Atomic(bundle_state_e) state;
void * handle;
bundle_archive_pt archive;
array_list_pt modules;
manifest_pt manifest;
celix_framework_t *framework;
};
//bundle.c
...
(*bundle)->state = ATOMIC_VAR_INIT(OSGI_FRAMEWORK_BUNDLE_INSTALLED);
...
state = atomic_load_explicit(&bundle->state, __ATOMIC_ACQUIRE);
...
atomic_store_explicit(&bundle->state, state, __ATOMIC_RELEASE);
...
```
This also means we bump the required compiler from gnu99 compatible to c11
compatible.
Seeing that it is 2020 I have no problem with that.
@abroekhuis, @rlenferink and @rbulter WDYT?
