html: properly percent-escape URLs
The only valid characters for a URL are unreserved characters a-zA-Z0-9_-.~ and the reserved characters !*'();:@&=+$,/?%#[] , as per RFC 3986. Everything else must be escaped. Additionally, the # and ? always have special meaning, and the &, =, and + have special meaning in a query string, so they too must be escaped. To make this easier, a table of escapes is now used so that we do not have to call fmt() for each character; if the entry is 0, no escaping is needed. Signed-off-by: Mark Lodato <lodatom@gmail.com>
