Corinna Vinschen a54bc198b1 Implement correct RLIMIT_STACK handling
* miscfuncs.cc (struct pthread_wrapper_arg): Add member guardsize.
        (pthread_wrapper): Set thread stack guarantee according to guardsize.
        Tweak assembler code so that $rax/$eax is not required by GCC to
        prepare the wrapper_arg value.
        (CygwinCreateThread): Fix deadzone handling.  Drop setting a "POSIX"
        guardpage (aka page w/ PAGE_NOACCESS).  Always use Windows guard
        pages instead.  On post-XP systems (providing SetThreadStackGuarantee)
        always set up stack Windows like with reserved/commited areas and
        movable guard pages.  Only on XP set up stack fully commited if the
        guardpage size is not the default system guardpage size.
        Fill out pthread_wrapper_arg::guardsize.  Improve comments.
        * resource.cc: Implement RSTACK_LIMIT Linux-like.
        (DEFAULT_STACKSIZE): New macro.
        (DEFAULT_STACKGUARD): Ditto.
        (rlimit_stack_guard): New muto.
        (rlimit_stack): New global variable holding current RSTACK_LIMIT values.
        (__set_rlimit_stack): Set rlimit_stack under lock.
        (__get_rlimit_stack): Initialize rlimit_stack from executable header
        and return rlimit_stack values under lock.
        (get_rlimit_stack): Filtering function to return useful default
        stacksize from rlimit_stack.rlim_cur value.
        (getrlimit): Call __get_rlimit_stack in RLIMIT_STACK case.
        (setrlimit): Call __set_rlimit_stack in RLIMIT_STACK case.
        * thread.cc (pthread::create): Fetch default stacksize calling
        get_rlimit_stack.
        (pthread_attr::pthread_attr): Fetch default guardsize calling
        wincap.def_guard_page_size.
        (pthread_attr_getstacksize): Fetch default stacksize calling
        get_rlimit_stack.
        * thread.h (PTHREAD_DEFAULT_STACKSIZE): Remove.
        (PTHREAD_DEFAULT_GUARDSIZE): Remove.
        (get_rlimit_stack): Declare.

Corinna Vinschen e426213a88 Disable fetching heap info on 64 bit XP/2003
* fhandler_process.cc (heap_info::heap_info): Disable fetching heap info
        on 64 bit XP/2003.  Explain why.
        * wincap.h (wincaps::has_broken_rtl_query_process_debug_information):
        New element.
        * wincap.cc: Implement above element throughout.
