PATCH: use gnulib modules instead of custom code

[Assaf Gordon]

Hello,

Several functions in the sed codebase have equivalent modules in gnulib
(likely did not exist when the code was originally written).

These 5 patches replace them:

sed: replace myname with gnulib's progname
sed: replace ck_realloc with gnulib's xrealloc/xnrealloc
sed: replace MALLOC/ck_malloc with gnulib's XCALLOC
sed: replace ck_strdup with gnulib's xstrdup
sed: replcae ck_memdup with gnulib's xmemdup


Comments welcomed,
