Pierrick BouvierandAlex Bennée c9e79557e4 semihosting/arm-compat-semi: compile once in system and per target for user mode 
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.

Pierrick BouvierandAlex Bennée d8028d4ede semihosting/guestfd: compile once for system/user 
We move relevant code to semihosting/arm-compat-semi.c, and add
functions to query CONFIG_ARM_COMPATIBLE_SEMIHOSTING at runtime.

Pierrick BouvierandAlex Bennée abc4522d01 semihosting/syscalls: compile once in system and per target for user mode 
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.

Philippe Mathieu-DaudéandAlex Bennée bb0c5be8e9 semihosting/meson: Build config.o and console.o once 
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.

Paolo Bonzini 5837db4650 semihosting: move stubs out of stubs/ 
Since the semihosting stubs are needed exactly when the Kconfig symbols
are not needed, move them to semihosting/ and conditionalize them

Philippe Mathieu-DaudéandRichard Henderson c7b64948f8 meson: Replace CONFIG_SOFTMMU -> CONFIG_SYSTEM_ONLY

use the clearer 'CONFIG_SYSTEM_ONLY' key to check

Richard Henderson 5b3f39cb04 semihosting: Split out semihost_sys_open 
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.
