Arun Sharma 3468a6b33d Change MS_SYNC to MS_ASYNC 
Hopefully this makes the address validation a bit cheaper.

Paul Pluzhnikov 0cf76ed0b5 Check for NULL when validating addresses 
This is rather on the obvious side.

While doing strace on an executable using libunwind, I noticed a
lot of:

  msync(0, 1, MS_SYNC) = -1 ENOMEM (Cannot allocate memory)

Since we know that the first page isn't mapped (or at least doesn't
contain the data we are looking for), we can eliminate all such
msync calls.

Tested on Linux/x86_64 with no regressions.

David Mosberger-Tang 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.
