Added templates required_shared_ptr<> and optional_shared_ptr<> which
work just like required_device<> and optional_device<> for retrieving a
pointer by tag from an address space that specifies AM_SHARE("tag").
Also added templates required_shared_size<> and optional_shared_size<>
for retrieving the size of the AM_SHARE region.
Created a new generic NVRAM device. It can be configured to default to
0-fill, 1-fill, random-fill, or custom fill. In all cases, a same-named
memory region overrides the default fill. The address range where the
NVRAM can be found is now identified by an AM_SHARE() region of the
same tag as the NVRAM device. Drivers can also explicitly configure a
separately-allocated NVRAM region via nvram_device::set_base().
Replaced all instances of MDRV_NVRAM_HANDLER(generic_*) with
MDRV_NVRAM_ADD_*("nvram"). Replaced all AM_BASE_GENERIC/AM_SIZE_GENERIC(nvram)
with AM_SHARE("nvram"). For all remaining drivers that referenced the
generic.nvram directly, changed them to hold a required_shared_ptr<UINTx>
to the NVRAM in their driver state, and use that instead. Removed
nvram and nvram_size from the generic_ptrs.
