Thanks to Scott Davis' detailed reports, I found this premature detection
of the end of a chunked-encoded POST request.

detabify

include ctype.h for isdigit()

Bug report #1204435 identified a problem with malformed URLs like
"http://somehost?data" as it added a slash too much in the request ("GET
/?data/"...). Added test case 260 to verify.

Moved more generic functions to util.[ch]
Added resolve.c to simply resolve a given host name

always use the libcurl-provided *printf() functions

Moved common code to util.[ch] instead of having it duplicated in sws.c
and sockfilt.c. For good-to-have functions for the servers written in C.

display listening port in log

Updated the copyright year since changes have been this year.

modified some log outputs, added comment about auth required as used in
test 154

make sure the ipv6 http server gets its pid stored in a separate file

Fixed missing braces warning.

Missing 'in6addr_any' in MingW's lib. ld bug?

HTTP IPv6 support added to the test suite

close the connection when a bad test number was requested

added comment about port number in CONNECT string being used as test number

Enable test cases to provide sections base64-encoded to be able to test
with binary data.

use curlx_strnequal() from the private lib sources instead of strncasecmp()
for maximum portability

modified some logging output

when the client disconnects prematurely, dump the request as received thus
far

skip the pid from the logging

delete trailing whitespace

%ld for long

int/long fix

include the full size of the sent response in the log
