For arm-compat, initialize console_{in,out}_gf;
otherwise, initialize stdio file descriptors.
This will go some way to cleaning up arm-compat, and
will allow other semihosting to use normal stdio.

Rename qemu_semihosting_connect_chardevs to
qemu_semihosting_chardev_init; pass the result
directly to qemu_semihosting_console_init.
Store the chardev in SemihostingConsole instead
of SemihostingConfig, which lets us drop
semihosting_get_chardev.

Allow more than one character to be read at one time.
Will be used by m68k and nios2 semihosting for stdio.

We don't need CPUArchState, and we do want the CPUState of the
thread performing the operation -- use this instead of current_cpu.

Change 'ret' to uint64_t. This resolves a FIXME in the
m68k and nios2 semihosting that we've lost data.
Change 'err' to int. There is nothing target-specific
about the width of the errno value.

With the exception of hw/core/, the hw/ directory only contains
device models used in system emulation. Semihosting is also used
by user emulation. As a generic feature, move it out of hw/ directory.
