Generate "config.h" directly into the "include" directory, later copied

to "my_config.h". Not to pollute the top directory, and to get more control
over what is included. Made the include path for "libedit" pick up its own
"config.h" first.


config/ac-macros/misc.m4:
  aclocal in automake 1.8 can't handle AC_REQUIRE on
  a user macro defined in the same included file.
cmd-line-utils/libedit/Makefile.am:
  Changed include path so that current directory is taken first, as there
  is a "config.h" there with the same name as the one in top "include".
configure.in:
  Generate "config.h" directly into "include", don't pollute top directory
include/Makefile.am:
  Copy "config.h" from current directory to "my_config.h", added note in
  the make file why there are two identical files with different name.
scripts/make_binary_distribution.sh:
  Removed copy of "config.h" from top directory, it is in "include" in a
  source tree.
