ff0ae70cc3 Bad pointer validation for 32 bit x86.

ef29eade44 This patch eliminates one system call per unwind by not using the 
getcontext in libc.

Also cleanup the namespace (check-name-space passes on x86_64 now).
Replace uses of offsets.h with ucontext_i.h.
Rename _x86_64_setcontext to _Ux86_64_setcontext.

TBD: Add CFI annotations for get/setcontext.

649f1fb344 [X86-64] For local unwinding, we have a defence mechanism against 
bad/missing unwind information, which could result in libunwind
dereferencing bad pointers. This mechanism is based on msync(2) system
call and significantly reduces the chances of a bad pointer
dereference in libunwind.

The original idea was to turn this mechanism on only when necessary
i.e. libunwind didn't find proper unwind information for a IP.

There are a couple of problems in the current implementation.

* The flag is global and is modified without locking
* The flag isn't reset when starting a new unwind

The attached patch makes ->validate a per-thread setting by moving it
into struct cursor from unw_local_addr_space and resets it to false
when starting a new unwind. As a result, cursor->as_arg points to the
cursor itself instead of the ucontext (for the local case).

This was found to reduce the number of msync() system calls from an
application using libunwind significantly.

e6b9f350f7 Introduce a tdep_get_func_addr_hook() in the ELF lookup_symbol() 
routine and add address-space argument.  This is needed because on
PPC64, a the function-name symbol refers to a function descriptor
(unlike, for example, on ia64, where the @fptr() operator is needed to
refer to a function descriptor).  Thus, in order to look up the name
of a function, we need to dereference the function descriptor.  To
make matters more "interesting", the function descriptors are normally
resolved by the dynamic linker, so we can't get their values from the
ELF file.  Instead, we have to read them from the running image, hence
the need for the address-space argument.

1fdb08e5fc Various fixes to get x86 to compile and work again. 
include/dwarf.h: Declare dwarf_reg_state_pool and dwarf_cie_info_pool.
include/dwarf_i.h: Include libunwind_i.h instead of tdep.h.
	Make dwarf_to_unw_regnum() a macro so it doesn't get compiled
	into an object file merely because it include dwarf_i.h (important
	when optimization is turned off).
	(dwarf_read_encoded_pointer_inlined): New function.
include/tdep-x86/libunwind_i.h: Add include of "mempool.h".
include/tdep-x86_64/libunwind_i.h: Add include of "mempool.h".

11ea1275bd [dwarf] The sword() function in Gexpr.c doesn't do what's intended. 
Yes, it casts to signed, but then converts right back to
unsigned via the return type.  Fixed thus.
