Create a method of disabling the debug allocation code paths so that
it's possible to use the libunwindbacktrace library without any
modifications.
Use this path to create and destroy the maps for the process. It's not
stricly necessary in the init code since the symbols are not modified
until after the initialize calls.
Also, remove the debug_XXX source files that doesn't need to be in libc.so.
Fix the maps reading code since it was completely broken for 64 bit.

To avoid any issues calling malloc related routines, use mmap/munmap.
Specifically, this avoids any problems when this is compiled into a
malloc debug shared library.

To use jemalloc, add MALLOC_IMPL = jemalloc in a board config file
and you get the new version automatically.
Update the pthread_create_key tests since jemalloc uses a few keys.
Add a new test to verify memalign works as expected.

Previously, we'd collect every stack frame and then throw some away
when we came to log them. This meant that stack traces were effectively
shorter than the buffers that had been allocated for them. This patch
only stores frames we'll actually output.
Also dynamically call the C++ demangler so we don't have to try to
read mangled names. Because no one knows the mangling of operator new[]
for int arrays off the top of their head.

We had two copies of the backtrace code, and two copies of the
libcorkscrew /proc/pid/maps code. This patch gets us down to one.
We also had hacks so we could log in the malloc debugging code.
This patch pulls the non-allocating "printf" code out of the
dynamic linker so everyone can share.
This patch also makes the leak diagnostics easier to read, and
makes it possible to paste them directly into the 'stack' tool (by
using relative PCs).
This patch also fixes the stdio standard stream leak that was
causing a leak warning every time tf_daemon ran.
