request read on a connection, which allows us to generate the correct
type of response in case of an error which is handled through
`handle-server-error'.
Also added code to correctly escape text that is inserted into error
messages. This is also a first step towards preventing cross-scripting
attacks through CLASH, although most of the code still has to be audited
for unfiltered passing through of user-supplied text.
quoted-strings in both key and values of key value pairs and in simple
lists correctly. Also factored out all magic constants, added some
stuff to make this halfway efficient (profiling to be done). This
rewrite makes partition superfluous, maybe remove this from
src/utility.cl.
Added parsing of Base64 and authorization credentials.
Moved some of the common parsing and rendering subroutines to a new
file. Many other functions should probably be moved over here, so
watch this space as clean up progresses further.
