The rename source is now resolved before the destination argument, as in
FreeBSD kern_renameat, so sceKernelRename("src", nullptr) fails with ENOENT
when src does not exist. GuestPosixScalarIo still expected EFAULT.

On Windows, pipe_nid_postfix configured the anonymous pipe with a 4096-byte buffer. When guest executables redirect standard error to a pipe via dup2 and host logging writes to standard error, the pipe buffer fills during startup before or between guest reader drains, blocking writer threads in ZwWriteFile and deadlocking the title. Increase the Windows pipe buffer capacity to 65536 bytes to match FreeBSD BIG_PIPE_SIZE used by the PS5 kernel, and cover multi-page single-shot pipe writes in guest posix scalar IO tests.
FreeBSD's read, write, pread and pwrite reject a byte count above
IOSIZE_MAX with EINVAL before they look up the descriptor. write threw
std::invalid_argument for a negative count, and the others passed the
count on to the host, which reports EFAULT on Linux.

read and write already fail with EFAULT for a null buffer and a
non-zero length and treat a zero-length null buffer as empty. The
sceKernel entry points threw std::invalid_argument for both. They now
do the same as read and write.
