Vitaliy Filippov fcabfc89e9 Introduce VectoredReadOp 
Read requests can now take vectored responses from the filesystem
implementation and send them to FUSE device via the writev() system call.

This allows file systems to send data without copying it into the
library-provided buffer if the data is already in memory.

The change also speeds up normal ReadFileOps as a side effect because
it removes extra memory allocations.

Michael Stapelberg 0630024b2b switch from assembly stubs to go:linkname comment 
The go:linkname way works with Go 1.17 (with regabi), too.

Upstream did this in 2015 in
0b8d583320

See also https://sitano.github.io/2016/04/28/golang-private/ for more background
about both techniques.

I misunderstood what was being zeroed. Only the header is.
