Carriage return and process-send-string

[Vibhav Pant]

While working on a library for the Language Server Protocol[1] (which
uses \r\n to
separate headers), I found out that `process-send-string` will convert
carriage returns in
the provided string to newlines. As an example, strace shows that

(process-send-string proc
    (format "Content-Length: 0\r\n\r\n")

ends up sending

read(0, "Content-Length: 0\n", 8192)  = 17
read(0, "\n", 8192)                     = 1
read(0, "\n", 8192)                     = 1
read(0, "\n", 8192)                     = 1

to the process. I tried setting `:coding-system` in `make-process` to
`'no-conversion`, but
this didn't fix the issue. Is this intended behavior? If so, are there
any ways to go around it?

Thanks,
Vibhav
