* autoload.cc (SetThreadStackGuarantee): Import.
* cygtls.h (struct _cygtls): Replace thread_context with a ucontext_t
called context.
* exceptions.cc (exception::handle): Exit from process via signal_exit
in case sig_send returns from handling a stack overflow SIGSEGV.
Explain why.
(dumpstack_overflow_wrapper): Thread wrapper to create a stackdump
from another thread.
(signal_exit): Fix argument list to reflect three-arg signal handler.
In case we have to create a stackdump for a stack overflow condition,
do so from a separate thread. Explain why.
(sigpacket::process): Don't run signal_exit on alternate stack.
(altstack_wrapper): Wrapper function to do stack correction when
calling the signal handler on an alternate stack to handle a stack
overflow. Make sure to have lots of comments.
(_cygtls::call_signal_handler): Drop local context variable to reduce
stack pressure. Use this->context instead. Change inline assembler
to call altstack_wrapper.
(_cygtls::signal_debugger): Accommodate aforementioned change to
struct _cygtls.
* tlsoffset.h: Regenerate.
* tlsoffset64.h: Regenerate.
