Implement nacl_irt_fdio for non-sfi mode.

This CL implements nacl_irt_fdio for non-sfi mode.
Note that getdents is currently not supported because there is no good way to
implement it in a sane manner. Now it always returns ENOSYS.

TEST=Tried to call a newly added function from plugin via AT_SYSINFO.

Moves IME's views specific code out from chrome/browser/chromeos.

Now UI code of input methods -- candidate window, infolist
window, and mode indicator -- is pure views and doesn't need
to be in c/b.

I chose ash/ime because they are ash-specific UI, but I'm
okay to move to another place. Please tell me if you have
other ideas.
