The current bss clear logic assumes the target mmap address and host
address are the same. Use g2h to translate from the target address
space to the host so we can call memset on it.

This brings flatload.c more in line with the current Linux FLAT loader
which allows targets to handle various FLAT aspects in their own way.
For the common behavior, the new functions get stubbed out.

The current auto-stack sizing works like it does on a NOMMU system; the
problem is that this only works if the envp/argv arrays are fairly slim.
On a desktop system, this is rarely the case, and can easily blow past
the stack and into data/text regions as the default stack for FLAT progs
is a mere 4KiB. So rather than rely on the NOMMU calculation (which is
only there because NOMMU can't easily allocate gobs of contiguous mem),
calc the full space actually needed and let the MMU host make space.

Because of the use of unsigned type, possible errors during
load were ignored.
Fix by using a signed type.
This also avoids a warning with GCC flag -Wtype-limits.

When loading a shared library that requires an executable stack,
glibc uses the mprotext PROT_GROWSDOWN flag to achieve this.
We don't support PROT_GROWSDOWN.
Add a special case to handle changing the stack permissions in this way.
