Alejandro Colomar 881c1d63a1 libmisc: Move xmalloc.c to alloc.c
We'll expand the contents in a following commit, so let's move the file
to a more generic name, have a dedicated header, and update includes.

Signed-off-by: Alejandro Colomar <alx@kernel.org>

Use the new header for xstrdup()

/* Replacements for malloc and strdup with error checking. Too trivial
to be worth copyrighting :-). I did that because a lot of code used
malloc and strdup without checking for NULL pointer, and I like some
message better than a core dump... --marekm
Yeh, but. Remember that bailing out might leave the system in some
bizarre state. You really want to put in error checking, then add
some back-out failure recovery code. -- jfh */
