Pressing ^D in a non-empty input terminates LLDB. This was due to the fact that we stack more than one editline instance on top of each other and we still expect CTRL+D to exit the editline instance, but it should only do so when the line is empty. Otherwise it should (and does) delete the character at the cursor.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)

We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.
