Remove prototype support for C++ constructors, since it is not well
designed. Device drivers (or other application code) that requires an
automatic initialization capability should use the device initialization
macros instead.
Note: Support for C++ constructors may be re-introduced at a later date.
However, a number of issues need to be settled, such as when the
constructors are invoked and what context they run in. (Running them
during nanokernel initialization, as was previously done, is probably
not the right approach.)

As the system always operates in ring 0, neither the SS nor ESP registers
are pushed onto the stack when an exception or an interrupt occurs.
However, as the ESP field is still relevant to debugging fatal errors, a
place has been carved for it in the NANO_ESF.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).

This doesn't make any assumptions on calling conventions or
the structure of the stack, and should thus be portable to
compilers that implement different C calling conventions.
In order for the rewritten functions to take up the same code
size as the pure-asm counterparts, -fomit-frame-pointer has
been specified for each of them, otherwise an extra 4 bytes
is used for every function.
The generated assembly code by these new functions has been
verified in GDB to be the same as the old ones, except a few
trivial things like particular registers used.
