MINOR: channel: add new function co_getdelim() to support multiple delimiters

For now we have co_getline() which reads a buffer and stops on LF, and
co_getword() which reads a buffer and stops on one arbitrary delimiter.
But sometimes we'd need to stop on a set of delimiters (CR and LF, etc).

This patch adds a new function co_getdelim() which takes a set of delimiters
as a string, and constructs a small map (32 bytes) that's looked up during
parsing to stop after the first delimiter found within the set. It also
supports an optional escape character that skips a delimiter (typically a
backslash). For the rest it works exactly like the two other variants.
