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.

COFF has only one symbol table.
MachO has a LC_DYSYMTAB, but that is not a symbol table, just extra info about
the one symbol table (LC_SYMTAB).
IR (coming soon) also has only one table.

This change addresses shutdown crashes in the python lldb module when
the script interpreter was hanging on to saved file references after
leaving a session.  It also gets rid of extra references to the
stdin/stdout/stderr python file objects that are created when entering
the session.

This change also moves the bundled pyexpect 2.4 library to the front
of the python library path so that a python distribution default
pyexpect (2.3 in Ubuntu 12.04) is not picked up first.

Modern compilers (Clang 3.4, GCC 4.8) warn on variadic macros being
introduced in C99, which produces a huge number of useless diagnostics
since this macro is unused in the whole project.

The .object_arch directive indicates an alternative architecture to be specified
in the object file.  The directive does *not* effect the enabled feature bits
for the object file generation.  This is particularly useful when the code
performs runtime detection and would like to indicate a lower architecture as
the requirements than the actual instructions used.
