i#565 part 1: win8 version update

Updated all places where we store Windows versions:
+ windows_version_init()
+ tools.c get_windows_version()
+ dr_get_os_version()

Except not updating this until win8 support is all done:
+ -max_supported_os_version option

i#565 part 2: win8 syscall #s

Added the syscall numbers for win8 x86 and x64, and for the first time made
a separate column for wow64 due to the high-order bits being used instead
of ecx.

Reversed the columns so that new numbers are appened rather than inserted
at the beginning.

i#899: new win8 syscalls

Adds numbers for 3 new win8 syscalls the core may need to intercept.
Adds NYI asserts to catch execution so we can go figure them out.

NtUnmapViewOfSectionEx with new arg==0 is let through as it's the same as
NtUnmapViewOfSection.

i#565 part 3: syscall wrapper updates

There are quite a few wrapper differences which end up tripping DR all over
the place due to its many interactions with such wrappers:

+ syscalls_init() up-front syscall type check
+ intercept_syscall_wrapper()
+ clean_syscall_wrapper()
+ syscall param base for app syscall processing
+ add dynamorio_syscall_wow64_noedx which shifts retaddr
  so params are in right spot for calls from DR
+ wow64 post-syscall esp adjust is on win7 but not win8,
  for skipping syscalls and for invoke-another feature
+ win8 wow64 cleanup_and_terminate can't just use edx so I have it storing
  args on wow64_syscall_stack which I claim is safe
+ set_mcontext_for_syscall needs to pass args to an app syscall.
  I have it writing args to the app stack.  I can't clean them up.
  but it's only used for NtRaiseException, where changes
  to regs or even the stack will be unrolled or else the app will exit.

The checks for these are sometimes version checks for win8, and also:
+ added two routines for more general checks than "is it win8?":
  + syscall_uses_wow64_index()
  + !syscall_uses_edx_param_base()

i#899: handle new win8 syscall NtWow64AllocateVirtualMemory64 which it
turns out is just like NtAllocateVirtualMemory except it has an extra
unused arg inserted in the middle.

Fix bug in os_using_app_state() on linux where it returns the opposite of

event.

fixes issue 920

1) Fix bug in vfork: need to restore segment in parent, not child.
2) Do not call dynamo_thread_not_under_dynamo() for another thread
   as neither segment nor itimer syscalls can work that way.
   Windows no-asynch was already ignoring the dcontext arg.
3) Added asserts to enforce the executing-thread-only requirement.
