http-name->symbol broken

[felix winkelmann]

In intarweb, the procedure "http-name->symbol" assumes "string-downcase!" returns its result, but this is just incidental to the srfi-13 reference implementation. In utf CHICKEN, the procedure has been changed and returns the undefined value, making the intarweb primitive fail, which gets further obscured by exception handling in "parse-header-line".

To fix this, just use "string-downcase".

Thanks for pointing that out! I was under the (mistaken) impression that SRFI-13 used the same convention as SRFI-1 where an exclamation mark indicates the procedure *may* alter its input but it not required to, and will return the new object.

I've pushed intarweb 2.0.3 which fixes this. I'll have to remember to go through my other eggs to see if this incorrect notion infected those as well!
