Faster URL decodes in curl
I wrote a test program that uses a 1MB buffer in which byte sequences are stored from 0 to 255 over and over.
curl_easy_escape()is called, to generate a URL encoded version of that input.
curl_easy_unescape()is then called repeatedly to decode that huge string and I measure the time needed for it to complete 10000 iterations.
On my dev host, the new code runs 2.8 times faster.
