2019-04-17Convert poll/select to operate more directly on linux.PollFDMichael Pratt
Current, doPoll copies the user struct pollfd array into a []syscalls.PollFD, which contains internal kdefs.FD and waiter.EventMask types. While these are currently binary-compatible with the Linux versions, we generally discourage copying directly to internal types (someone may inadvertantly change kdefs.FD to uint64). Instead, copy directly to a []linux.PollFD, which will certainly be binary compatible. Most of syscalls/polling.go is included directly into syscalls/linux/sys_poll.go, as it can then operate directly on linux.PollFD. The additional syscalls.PollFD type is providing little value. I've also added explicit conversion functions for waiter.EventMask, which creates the possibility of a different binary format.
