This replaces the exit calls by shutdown requests, ensuring a proper
cleanup of Qemu. Otherwise, some connections like gdb could be broken
before its final packet ("Wxx") is being sent. This part, being done
inside qemu_cleanup function, can be reached only when the main loop
exits after a shutdown request.

The character that should be printed is stored in the 64 bit "payload"
variable. The code currently tries to print it by taking the address
of the variable and passing this pointer to qemu_chr_fe_write(). However,
this only works on little endian hosts where the least significant bits
are stored on the lowest address. To do this in a portable way, we have
to store the value in an uint8_t variable instead.

Add signature and signature-granularity properties in spike to specify the target
signatrue file and the line size for signature data.
Recgonize the signature section between begin_signature and end_signature symbols
when loading elf of ACT tests. Then dump signature data in signature section just
before the ACT tests exit.

At present create_fdt() calls htif_uses_elf_symbols() to determine
whether to insert a <reg> property for the HTIF. This unfortunately
creates a hidden dependency to riscv_load_{firmware,kernel} that
create_fdt() must be called after the ELF {firmware,kernel} image
has been loaded.
Decouple such dependency be adding a new parameter to create_fdt(),
whether custom HTIF base address is used. The flag will be set if
non ELF {firmware,kernel} image is given by user.

At present the HTIF proxy syscall is unsupported. On RV32, only
device 0 is supported so there is no console device for RV32.
The only way to implement console funtionality on RV32 is to
support the SYS_WRITE syscall.
With this commit, the Spike machine is able to boot the 32-bit
OpenSBI generic image.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

Currently, we have to use OpenSBI firmware ELF as bios for the spike
machine because the HTIF console requires ELF for parsing "fromhost"
and "tohost" symbols.
The latest OpenSBI can now optionally pick-up HTIF register address
from HTIF DT node so using this feature spike machine can now use
OpenSBI firmware BIN as bios.
