ReadPassword uses Windows ReadFile to read from console handle.
But ReadFile does not split input into UTF-8 characters, so ReadFile
only works when input is ASCII. Use os.File instead of Windows
ReadFile, because os.File reads console and parses it into UTF-8.

Move the README to README.md so Gerrit can render it; currently
Gerrit only renders files named exactly "README.md" (for example at
https://go.googlesource.com/go).
Add more links to the README explaining how to file issues,
how to submit code changes, where to download the code to and
how to get it. Hopefully this should help people who go to
https://go.googlesource.com/term or https://github.com/golang/term
figure out how to get started with development.

The Solaris version of MakeRaw already sets VMIN and VTIME explicitly
such that a read returns when one character is available.
cfmakeraw (whose behavior MakeRaw replicate) in glibc and the BSD's libc
also set these values explicitly, so it should be done in the Linux/BSD
versions of MakeRaw as well to be consistent.

18e6eb769a 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.

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.

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.

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.

Currently the ssh/terminal package cannot be compiled under gccgo. Even though gccgo may be running on linux, its syscall package is slightly different and does not contain these constants.
This proposal resolves the issue by declaring the two constants locally, as we've done for the *BSDs.

The length of history buffer entries (which are stored as strings) was

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.
