Ian Lance Taylor 5829c74886 unix: change Dup,Dup2,Dup3 to use Syscall, not RawSyscall
This avoids hanging when a Go program uses a FUSE filesystem and the
dup system call has to close a file descriptor.  When dup uses
RawSyscall then the goroutine calling dup will occupy a scheduler slot
(a p structure) during the call, and may block waiting for some other
goroutine to respond to the close call on the FUSE filesystem.
Changing to Syscall avoids the problem.  This makes Dup a tiny bit
slower but is quite unlikely to make a difference for any real
programs.

Update golang/go#10202.

Ian Lance Taylor 7f1554891e mksyscall.pl, types_linux.go: regenerate linux {386,amd64} files
Import syscall so that Kill can refer to syscall.Signal.  Drop
termios constants from types_linux.go--all other systems get
them from mkerrors.sh.

Fixes golang/go#8865.
