This patch adds the implementation of the custom operator new functions.
The implementation of the internal strdup has been updated to use
operator new for allocation.

We will make it a policy and document that all allocations have to go
through the libc's own operator new. A future change will also add
operator delete replacements and make it a policy that deallocations in
libc internal code have to go through those replacements.
