Subject: [PATCH] PR28575, readelf.c and strings.c use undefined type uint

Since --unicode support (commit b3aa80b45c4) both binutils/readelf.c
and binutils/strings.c use 'uint' in a few locations.  It likely
should be 'unsigned int' since there isn't anything defining 'uint'
within binutils (besides zlib) and AFAIK it isn't a standard type.

* readelf.c (print_symbol): Replace uint with unsigned int.
	* strings.c (string_min, display_utf8_char): Likewise.
	(print_unicode_stream_body, print_unicode_stream): Likewise.
	(print_strings): Likewise.
	(get_unicode_byte): Wrap long line.
