multi interface using examples

no longer include the multi dir, the examples should be in the examples
dir

moved to the new libcurl/ directory

ripped out from ../ and put in its own directory now

Added packages/EPM

Added EPM stuff, thanks to Giuseppe Corbelli

bug report #524427 pointed out a mistake in the example source

initial and still basic curl multi interface documentation

removed incorrect and unnecessary words

several little things since pre4

memanalyze is now moved to the tests/ dir

include memanalyze.pl in the dist archive

moved memanalyze.pl into the tests dir

Nico Baggus added more error codes to the VMS stuff.

Wesley Laxton's CURLOPT_PREQUOTE work

Ralph Mitchell's SSL problems made me notice that we didn't increase the
header byte counter properly

more fancy alloc, we store the size in each allocated block so that we
can destroy the full allocated area just before we free it

set CURL_MEMDEBUG to enable memory debugging in case curl is compiled
with it

added -t for trace, helps searching for leaks and similar

memory debugging is now only enabled if the CURL_MEMDEBUG environment
variable is set when curl is invoked

always allocates at least 64 bytes for real, and damages them before free

made building outside the source tree work again, Kevin Roth reported

minor edit

oops, we weren't doing HTTPS - now we are

test 304, HTTPS multipart formpost
