We don't have any target dependency left in system mode, so we can
compile once.
User mode depends on qemu.h, which is duplicated between linux and bsd,
so we can't easily compile it once.

We move relevant code to semihosting/arm-compat-semi.c, and add

We replace target_ulong mechanically by uint64_t.
We can't compile (easily) this code once for user, as it relies on
various target/function types, so leave it in specific_ss for user mode.

Avoid testing CONFIG_USER_ONLY in semihost.h.
The only function that's required is semihosting_enabled.

config.c and console.c don't use any target specific
headers anymore, move them from specific_ss[] to
system_ss[] so they are built once, but will also be
linked once, removing global symbol clash in a single
QEMU binary.

Since the semihosting stubs are needed exactly when the Kconfig symbols
are not needed, move them to semihosting/ and conditionalize them
on CONFIG_SEMIHOSTING and/or CONFIG_SYSTEM_ONLY.

Since we *might* have user emulation with softmmu,
use the clearer 'CONFIG_SYSTEM_ONLY' key to check

Split out the non-ARM specific portions of SYS_OPEN to a
reusable function. This handles gdb and host file i/o.
Add helpers to validate the length of the filename string.
Prepare for usage by other semihosting by allowing the
filename length parameter to be 0, and calling strlen.

In arm-compat-semi.c, we have more advanced treatment of
guest file descriptors than we do in other implementations.
Split out GuestFD and related functions to a new file so
that they can be shared.

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