When qemu is compiled without debug, the dump gdb python script can fail with:
Error occurred in Python command: No symbol "vmcoreinfo_find" in current context.
Because vmcoreinfo_find() is inlined and not exported.
Use the underlying object_resolve_path_type() to get the instance instead.

Let users of qemu_get_ram_ptr and qemu_ram_ptr_length pass in an
address that is relative to the MemoryRegion. This basically means
what address_space_translate returns.
Because the semantics of the second parameter change, rename the
function to qemu_map_ram_ptr.

All references to mr->ram_addr are replaced by
memory_region_get_ram_addr(mr) (except for a few assertions that are
replaced with mr->ram_block).

The module docstring is changed into a multi-line comment to comply
with pep 257.
The comment about the docstring that gets used by gdb to print the
help is moved to the location of the docstring.

By modelling the ELF with ctypes we not only gain full python 3
support but can also create dumps for different architectures more easily.

This commit does not make the script python 3 compatible, it is a
preparation that fixes the easy and common incompatibilities.
Print is a function in python 3 and therefore needs braces around its
arguments.
Range does not cast a gdb.Value object to int in python 3, we have to
do it ourselves.

The functions dealing with qemu components rarely used parts of the
class, so they were moved out of the class.
As the uintptr_t variable is needed both within and outside the class,
it was made a constant and moved to the top.
