What's new:
-----------
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.

- Handle pthread stacksizes as in GLibc: Default to RLIMIT_STACK resource.
Allow to set RLIMIT_STACK via setrlimit. Default RLIMIT_STACK to value
from executable header as described on
https://msdn.microsoft.com/en-us/library/windows/desktop/ms686774.aspx
Default stacksize to 2 Megs in case RLIMIT_STACK is set to RLIM_INFINITY.
Add alternate signal stack to docs * new-features.xml (ov-new2.1): Add alterante signal stack info. * posix.xml (std-susv4): Move sigaltstack here. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- First cut of an implementation to allow signal handlers running on an
alternate signal stack.
- New API sigaltstack, plus definitions for SA_ONSTACK, SS_ONSTACK, SS_DISABLE,
MINSIGSTKSZ, SIGSTKSZ.
Add sethostname * net.cc (sethostname): New function. * common.din (sethostname): Export * include/cygwin/version.h (CYGWIN_VERSION_DLL_MAJOR): Bump to 2001. (CYGWIN_VERSION_DLL_MINOR): Set to 0. * new-features.xml (ov-new): Rename from ov-new1.7. (ov-new2.1): Add new section. Document sethostname. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- Apparently on some Windows systems timezones differ in case
from the standard. Fix the tzset tool to check case-insensitive.
