* encoding.c (rb_enc_nth): moved to string.c.

* string.c (rb_enc_nth): moved from string.c. use search_nonascii for ASCII compatible string. (str_nth): wrong optimization removed to fix "a".force_encoding("EUC-JP").slice!(0,10) returns "a\x00\x00\x00\x00\x00\x00\x00\x00\x00" git-svn-id: http://svn.ruby-lang.org/repos/ruby/trunk@15492 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

 * Interpretation of offset for color fields: All offsets are from the right,
 * inside a "pixel" value, which is exactly 'bits_per_pixel' wide (means: you
 * can use the offset as right argument to <<). A pixel afterwards is a bit
 * stream and is written to video memory as that unmodified.
 *
 * For pseudocolor: offset and length should be the same for all color
 * components. Offset specifies the position of the least significant bit
 * of the pallette index in a pixel value. Length indicates the number
 * of available palette entries (i.e. # of entries = 1 << length).
