* module/web/response.scm (read-response-body/latin-1): Avoid the
craziness of the read-delimited! interface and hand-roll our
own. Fixes errors if read-delimited returns #f or EOF.
* module/web/request.scm (read-request-body/latin-1):
* module/web/response.scm (read-response-body/latin-1): Detect short
reads instead of returning a full buffer with the last bits zeroed
out. (Before the make-string commit, they contained uninitialized
memory, which was a fairly serious error.)
* module/web/request.scm (<request>): Add `meta' field and accessor, for
metadata like the server IP, the client IP, CGI environment variables,
etc.
(build-request): Add meta kwarg.
(read-request): Add meta optional arg.
(write-request): Adapt.
