fix dependencies. (what is a .lo anyway? i tried making the .o depend on the .h which is how dependencies usually work, but the other rules didn't work out right unless i used a .lo ... i suppose this only matters to folks building with -j N)
APACHE_XLATE, CHARSET_EBCDIC stuff: Provide new function ap_set_content_xlate() to simplify what needs to be done to set up translation of content. Use it where appropriate.
With this change, EBCDIC logic was tweaked so that ap_checkconv() does not overlay a translation handle previously stored (e.g., by a module) unless it is turning translation off. Unless ap_checkconv() determines that translation is inappropriate, it should leave the translation handle alone.
