libdot: drop FileError handling for DOMError

Starting with Chrome 53, the FileError interface no longer exists.
They're pushing people to work with DOMError objects instead.

We can drop lib.fs.installFileErrorToString as the issue it addresses
no longer exists: DOMError only provides a .name member and does not
provide a .code field at all.

We can also drop lib.fs.getFileErrorMnemonic for the same reason --
there is no code anymore to look up.  Plus, there do not appear to be
any callers of this API.

TEST=loading secure shell still works

Top level directories

  • libdot/ is a small set of JS libraries initially developed as part of hterm, now available as shared code. It provides a base layer for web applications. The code is intended to work in any modern browser, in either a plain web page or a “privileged” environment such as a Chrome platform application or Firefox extension. In practice, it's only been put to use in Chrome platform applications so far.

  • hterm/ is a JS library that provides a terminal emulator. It is reasonably fast, reasonably correct, and reasonably portable across browsers.

  • nassh/ is the SecureShell Chrome App (currently a “v1.5” app, soon to become a “v2” or platform app) that combines hterm with a NaCl build of OpenSSH to provide a PuTTY-like app for Chrome users.

  • wash/ is a library for cross-origin virtual filsystems, similar to the Plan 9 filesystem. This directory also contains a simple bash-like shell environment for exploring these filesystems. The code in this directory is a work-in-progress.
