linux-user: Move syscall error detection into safe_syscall_base

The current api from safe_syscall_base() is to return -errno, which is
the interface provided by *some* linux kernel abis. The wrapper macro,
safe_syscall(), detects error, stores into errno, and returns -1, to
match the api of the system syscall().

For those kernel abis that do not return -errno natively, this leads
to double syscall error detection. E.g. Linux ppc64, which sets the
SO flag for error.

Simplify the usage from C by moving the error detection into assembly,
and usage from assembly by providing a C helper with which to set errno.

bsd-user pull request: merge dependencies for next architectures

Merge the dependencies for arm, aarch64, and riscv64 architectures. This joins
together two patch series:

[PATCH v2 00/15] bsd-user: misc cleanup for aarch64 import

Prepare for aarch64 support (the next architecture to be upstreamed). As the
aarch64 emulation is more complete, it relies on a number of different items.
In some cases, I've pulled in the full support from bsd-user fork. In other
cases I've created a simple stub (as is the case for signals, which have
independent changes pending, so I wanted to be as minimal as possible. Since
all pre-12.2 support was purged from the bsd-user fork, go ahead and remove it
here. FreeBSD 11.x goes ouft of support at the end of the month. Remove what
little multi-version support that's in upstream.

and

[PATCH v3 0/9] bsd-user mmap fixes
This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug
fixes pulled in from linux-user, as well as some newer fixes to adress bugs
found in check-tcg and recent FreeBSD developments. There are also a couple of
style commits. Updated to migrate debugging to qemu_log.

as well as a couple of minor rebase tweaks. In addition, the next two
architectures I plan on upstreaming (arm and riscv64) also have their prereqs
satisfied with this request.

v2: Remove accidental module regression in patch 7 and try again.

semihosting: Move ARM semihosting code to shared directories

This commit renames two files which provide ARM semihosting support so
that they can be shared by other architectures:

1. target/arm/arm-semi.c -> hw/semihosting/common-semi.c
2. linux-user/arm/semihost.c -> linux-user/semihost.c

The build system was modified use a new config variable,
CONFIG_ARM_COMPATIBLE_SEMIHOSTING, which has been added to the ARM
softmmu and linux-user default configs. The contents of the source
files has not been changed in this patch.

meson: linux-user

The most interesting or most complicated part here is the syscall_nr.h
generators. In order to keep the generation logic all in meson.build,
I am adding to config_target the name of the .tbl file, and making the
generated file syscall<SUFFIX>_nr.h for input file syscall<SUFFIX>.tbl.

For architectures where the input file is not named syscall_nr.tbl,
syscall_nr.h has to be a source file; it's just a forwarder for x86
(i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.
