Kevin Burke e8f229864d all: fix errors reported by vet, golint
None are "wrong" per se, but there are a lot of good suggestions and
in one case a docstring that was not present in godoc due to the
presence of an extra newline.

Changed "Id" in struct properties to "ID" in some non-exported
structs. Removed a trailing period from some error messages; I believe
the exact contents of error strings are not covered by the Go
compatibility promise.

According to the io.Reader docs, Alex had it right the first time. (See
discussion on https://golang.org/cl/25355.)

Adam Langley 95cb608f36 x/crypto/ssh/terminal: replace \n with \r\n.
911fafb28f made MakeRaw match C's behaviour. This included clearing the
OPOST flag, which means that one now needs to write \r\n for a newline,
otherwise the cursor doesn't move back to the beginning and the terminal
prints a staircase.

(Dear god, we're still emulating line printers.)

This change causes the terminal package to do the required
transformation.

Fixes golang/go#17364.

Derek Che a7ead6ddf0 ssh/terminal: fix SetSize when nothing on current line
SetSize has a problem may cause the following ReadPassword setting
temporary prompt not working, when changing width the current
SetSize will call clearAndRepaintLinePlusNPrevious which would
print an old prompt whatever the current line has, causing a following
ReadPassword with temporary prompt not printing the different prompt.

When running code like this, the nt.SetSize prints a "> " as
prompt then the temporary "Password: " prompt would never show up.

```go
        oldState, err := terminal.MakeRaw(int(os.Stdin.Fd()))
        width, height, _ = terminal.GetSize(int(os.Stdin.Fd()))
        nt := terminal.NewTerminal(os.Stdin, "> ")
        nt.SetSize(width, height)
        password, err = nt.ReadPassword("Password: ")
```

the new test cases is to test SetSize with different terminal sizes,
either shrinking or expanding, a following ReadPassword should get the
correct temporary prompt.

Adam Langley 5ff91abc76 go.crypto/ssh/terminal: support bracketed paste mode.
Some terminals support a mode where pasted text is bracketed by escape sequences. This is very useful for terminal applications that otherwise have no good way to tell pastes and typed text apart.

This change allows applications to enable this mode and, if the terminal supports it, will suppress autocompletes during pastes and indicate to the caller that a line came entirely from pasted text.

Adam Langley 7780ec1765 go.crypto/ssh/terminal: fix crash when terminal narrower than prompt.
Previously, if the current line was "empty", resizes wouldn't trigger
repaints. However, the line can be empty when the prompt is non-empty
and the code would then panic after a resize because the cursor position
was outside of the terminal.

Adam Langley 76cee1b7b1 go.crypto/ssh/terminal: better handling of window resizing.
There doesn't appear to be perfect behaviour for line editing
code in the face of terminal resizing. But this change works
pretty well on xterm and gnome-terminal and certainly a lot
better than it used to.

Frithjof Schulze 153ce2a1d2 go.crypto/ssh/terminal: Allow ^A and ^E as synonyms for Home and End.
I understand that ssh/terminal can't implement everybodys
favorite keyboard shortcuts, but I think these are very
widespread. They exist not only in Emacs or Readline, but also
in Acme and Sam. Also they almost come for free.

Adam Langley 28dc961a18 go.crypto/ssh/terminal: fix non-ASCII history.
The length of history buffer entries (which are stored as strings) was
being used as the number of runes. This was correct until ff9ce887b46b,
which allowed unicode entry, but can now cause a panic when editing
history that contains non-ASCII codepoints.

Adam Langley cb60f353cb go.crypto/ssh/terminal: support Unicode entry.
Previously, terminal only supported ASCII characters. This change
alters some []byte to []rune so that the full range of Unicode is
supported. The only thing that doesn't appear to work correctly are
grapheme clusters as the code still assumes one rune per glyph. Still,
this change allows many more languages to work than did previously.
