htl: Move cleanup stack to variable shared between libc and pthread
If libpthread gets loaded dynamically, the stack needs to already contain the cleanup handlers of the main thread. * htl/libc_pthread_init.c (__pthread_cleanup_stack): New per-thread variable. * htl/Versions (libc): Add __pthread_cleanup_stack as private symbol. * htl/pt-internal.h (struct __pthread): Remove cancelation_handlers field. (__pthread_cleanup_stack): Add variable declaration. * htl/pt-alloc.c (initialize_pthread): Remove initialization of cancelation_handlers field. * htl/pt-cleanup.c (__pthread_get_cleanup_stack): Return the address of __pthread_cleanup_stack instead of that of the cancelation_handlers field. * htl/forward.c: Include <pt-internal.h>. (dummy_list): Remove variable. (__pthread_get_cleanup_stack): Return the address of __pthread_cleanup_stack instead of that of dummy_list.
