[PATCH 1/2] Define macros for renaming xmalloc and xcalloc

[Masatake YAMATO]

I'm planning to link strace with libiberty for mangling C++
symbol appearted in stack trace enabled with -k option.

Both the names, xmalloc and xcalloc, are already used in the
library. They are conflicts the functions having the same
names in strace. Newly introduced macors(strace_calloc and
strace_malloc) rename the names defined in strace side for
avoiding the confliction.

* xmalloc.h (strace_calloc, strace_malloc): New macros.
