ICU-1220 Added escape-codepoint as a callback to let people use the

Browse Source 
new UCNV_ESCAPE_CODEPOINT.
Options compatibility with iconv(1): added -V, --version; -s, --silent;
--verbose (and -v because of ICU commands); -o, --output file. uconv(1) is
now mostly compatible with iconv(1) usage, except for the fact that one
cannot convert many files in one run yet.
