Implement -Xss.
* include/jvm.h (gcj::stack_size): Declare.
(_Jv_StackSize): Declare.
* posix-threads.cc (_Jv_InitThreads): Validate gcj::stack_size.
(_Jv_ThreadStart): Set stack size if specified.
* prims.cc (gcj::stack_size): Define.
(parse_memory_size): Renamed from parse_heap_size.
(_Jv_SetStackSize): Parse stack size argument and set gcj::stack_size.
NetBSD does not define PTHREAD_STACK_MIN, so this breaks bootstrap.
Something along the line of the patch below need to be committed on
the trunk, gcc-4_0-branch, and gcc-4_1-branch.
The patch has been bootstrapped and regtested on i386-unknown-netbsdelf2.1
for the tree branches.
