reencode_string(): introduce and use same_encoding()
Callers of reencode_string() that re-encodes a string from one encoding to another all used ad-hoc way to bypass the case where the input and the output encodings are the same. Some did strcmp(), some did strcasecmp(), yet some others when converting to UTF-8 used is_encoding_utf8(). Introduce same_encoding() helper function to make these callers use the same logic. Notably, is_encoding_utf8() has a work-around for common misconfiguration to use "utf8" to name UTF-8 encoding, which does not match "UTF-8" hence strcasecmp() would not consider the same. Make use of it in this helper function. Signed-off-by: Junio C Hamano <gitster@pobox.com>
