linux-user: Always exit from exclusive state in fork_end()
fork()ed processes currently start with
current_cpu->in_exclusive_context set, which is, strictly speaking, not
correct, but does not cause problems (even assertion failures).
With one of the next patches, the code begins to rely on this value, so
fix it by always calling end_exclusive() in fork_end().

linux-user: Allow sendmsg() without IOV

sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=NULL, msg_iovlen=0,
msg_control=[{cmsg_len=36, cmsg_level=SOL_ALG, cmsg_type=0x2}],
msg_controllen=40, msg_flags=0}, MSG_MORE) = 0
sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="The quick brown fox jumps over t"..., iov_len=183}],
msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_ALG, cmsg_type=0x3}],
msg_controllen=24, msg_flags=0}, 0) = 183
The function do_sendrecvmsg_locked() is used for sndmsg() and recvmsg()
and calls lock_iovec() to lock the IOV into memory. For the first
sendmsg() above it returns NULL and thus wrongly skips the call the host
sendmsg() syscall, which will break the calling application.
Fix this issue by:
- allowing sendmsg() even with empty IOV
- skip recvmsg() if IOV is NULL
- skip both if the return code of do_sendrecvmsg_locked() != 0, which
indicates some failure like EFAULT on the IOV

linux-user: Add emulation for MADV_WIPEONFORK and MADV_KEEPONFORK in madvise()
Both parameters have a different value on the parisc platform, so first
translate the target value into a host value for usage in the native
madvise() syscall.
Those parameters are often used by security sensitive applications (e.g.
tor browser, boringssl, ...) which expect the call to return a proper
return code on failure, so return -EINVAL if qemu fails to forward the
syscall to the host OS.
While touching this code, enhance the comments about MADV_DONTNEED.
Tested with testcase of tor browser when running hppa-linux guest on
x86-64 host.

linux-user: Fix /proc/cpuinfo output for hppa
The hppa architectures provides an own output for the emulated
/proc/cpuinfo file.
Some userspace applications count (even if that's not the recommended
way) the number of lines which start with "processor:" and assume that
this number then reflects the number of online CPUs. Since those 3
architectures don't provide any such line, applications may assume "0"
CPUs. One such issue can be seen in debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1024653
Avoid such issues by adding a "processor:" line for each of the online
CPUs.

linux-user: move target_flat.h to target subdirs
This makes target_flat.h behave like every other target_xxx.h header.
It also makes it actually work -- while the current header says adding
a header to the target subdir overrides the common one, it doesn't.
This is for two reasons:
* meson.build adds -Ilinux-user before -Ilinux-user/$arch
* the compiler search path for "target_flat.h" looks in the same dir
as the source file before searching -I paths.
This can be seen with the xtensa port -- the subdir settings aren't
used which breaks stack setup.
Move it to the generic/ subdir and add include stubs like every
other target_xxx.h header is handled.

linux-user: un-parent OBJECT(cpu) when closing thread
This reinstates commit 52f0c1607671293afcdb2acc2f83e9bccbfa74bb:
While forcing the CPU to unrealize by hand does trigger the clean-up
code we never fully free resources because refcount never reaches
zero. This is because QOM automatically added objects without an
explicit parent to /unattached/, incrementing the refcount.
Instead of manually triggering unrealization just unparent the object
and let the device machinery deal with that for us.
