(#2263)
* Created a more flexible imgtool::datetime structure for use within Imgtool
This is intended to replace most usage of time_t
* Changing the granularity of imgtool_clock from 1ms to 100ns, as per Vas' suggestion
* Created arbitrary_datetime in timeconv.h to facilitate interpretation of datetime info
I concluded that invoking std::mktime on manually assembled std::tm is bad, because it is indeterminate how the std::tm members may be "dominant". This required that I go further in imgtool, and update a number of drivers and eliminate the parameter of imgtool::datetime that takes std::tm.

Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8

They always took ownership of the stream; this just makes it official. Because the ownership would only traditionally happen if the open() or create() succeeded, I had to do a clumsy pattern where I call get() at the beginning of the callback to get the stream, but later on release() immediately prior to succeeding.

Still a bit of work to do, most notably around adoption of std::unique_ptr<>, which may be a challenge here on account of some assumptions regarding lifetime of streams by modules.

This also eliminated the need for get_sector_size
The asute reviewer will note that a side effect of this change is that in scenarios where we once returned IMGTOOLERR_OUTOFMEMORY, we now throw std::bad_alloc. This is deliberate. Having an error code for out of memory conditions no longer makes sense with MAME's embrace of the C++ way of doing things. It is highly likely that I will follow up this change with one that eliminates IMGTOOLERR_OUTOFMEMORY in favor of throwing std::bad_alloc.
This commit also fixes a recent regression in which we passed nullptr to an std::string ctor

The main point of this change is to C++-ify option_guide. It was changed from a struct array to a class, namespaced etc, with the ultimate hope of incorporating an in-emulation image creation UI.
Imgtool got hit with a number of changes; I'll probably have to bring that off of the backburner and touch that up too
