the opportunity to move the handlers from syswrap-generic.c (which
they certainly aren't) to syswrap-linux.c. Fixes#175044.

Also expands pathname arguments as strings in a lot more system call
trace messages and fixed the poll wrapper to not be x86 specific.

source it turns out that there are five different versions of mmap for
the three platforms we currently support:
- On x86-linux there is mmap (aka old_mmap) which takes the
arguments in a memory block and the offset in bytes; and
mmap2 (aka sys_mmap2) which takes the arguments in the normal
way and the offset in pages.
- On ppc32-linux there is mmap (aka sys_mmap) which takes the
arguments in the normal way and the offset in bytes; and
mmap2 (aka sys_mmap2) which takes the arguments in the normal
way and the offset in pages.
- On amd64-linux everything is simple and there is just the one
call, mmap (aka sys_mmap) which takes the arguments in the normal
way and the offset in bytes.
To reconcile all this I have created a generic handler and then
written five platform specific wrappers which normalise all the
arguments and then call the generic handler.
I have also modified the address space manager to use mmap2 rather
than mmap on x86 and ppc32 so that large offsets can be correctly
handled.
There is still an issue of OffT truncating offsets as we go through
the address space manager that will need to be addressed.

module-local, use the new ML_ prefix instead of VG_. This makes it
trivial to see which names are those exported from public module
interfaces: precisely those using VG_.
/* VG_ is for symbols exported from modules. ML_ (module-local) is
for symbols which are not intended to be visible outside modules,
but which cannot be declared as C 'static's since they need to be
visible across C files within a given module. It is a mistake for
a ML_ name to appear in a pub_core_*.h or pub_tool_*.h file.
Likewise it is a mistake for a VG_ name to appear in a priv_*.h
file.
