#9272 keeps liveStacks and protectedStackPages alive through static
destruction so that a late mprotect from an atexit handler can still
look up guest thread stacks. The mutex guarding them is still a static
std::mutex. libstdc++'s std::mutex has a trivial destructor, so it keeps
working on Linux, but libc++ destroys the pthread mutex, and a later lock
throws "mutex lock failed: Invalid argument": on macOS the exit probe of
guest_memory_lifetime fails at its mapping protection stage. The lock is
now allocated and never destroyed, like the maps.
The same change is part of #7201 and #8658.

FreeBSD keeps every character device on devfs, whose devfs_statfs reports
512-byte blocks, 2 blocks and nothing free. Windows threw for any console,
NUL or the guest random device, and Linux described the host's /dev mount.
A kqueue now returns EINVAL, as getvnode does.

The EINVAL for a descriptor without a vnode now applies only to a pipe or socket. A character device is a vnode on FreeBSD, so getvnode succeeds and change_dir fails with ENOTDIR; File::IsCharacterDevice keeps that answer for the host character devices (a tty, NUL or /dev/null) and the guest random device. guest_kernel_sys pins it with /dev/random.

sosend_generic fails a send on a socket that can send no more with EPIPE
before it looks at so_error. Winsock reports the same send as WSAECONNABORTED
or WSAECONNRESET, which reached the guest as ECONNABORTED or ECONNRESET.
A stream send now maps both to EPIPE. The send-after-close checks of
guest_tcp, guest_socket_read_write and guest_socket_pair run on Windows too.

NpTrophy reads the trophy count and icons from the title's trophy
package (names are encrypted and stay not implemented), PS4 v1 save data
calls wrap the native v2/v3 ones, and NpWebApi library contexts, handles
and push event filters work offline (service filters fail without a
signed-in user). libSceAjm is built from the libSceAjm.native sources
for PS4 titles. Limbo's (CUSA01664) remaining PS4 imports, including the
synchronous PS4 TUS calls and the Facebook dialog calls next to the
existing libraries, are exported as not implemented.
FreeBSD 11.4's vn_seek fails SEEK_CUR and SEEK_END with EOVERFLOW when the base offset plus a positive offset does not fit in an off_t, and with EINVAL only when the result is negative. The host lseek reports EINVAL for the overflow, so the guest saw EINVAL. When the host call fails with EINVAL for a positive offset on SEEK_CUR or SEEK_END, the base position is read back and the call fails with EOVERFLOW if the sum would overflow; the file position is left unchanged.
