curl_formadd() now returns 'CURLFORMcode' instead of int, to better enable
checking for particular errors. curl/curl.h defines the errros

Roland Zimmermann's hint, we use SSL_CTX_use_certificate_chain_file() instead
of the previous one that used SSL_CTX_use_certificate_file()

removed compiler warnings

FreeBSD needs sys/types.h before we include sys/select.h that was included
mainly for AIX in the first place...! As reported in bug report #556869

Fixes bug report #556930 - we need to make sure that the data is all right
after we've realloc() the packed hostent struct.

Added item 4.10 after talks with Russ Freeman

7.9.7 commit

we don't need win32sockets.c anymore, we support this internally

fopen.c added, a fopen() style emulation for URL reading

Friday's fixes

AIX 5.1

Kein Roth made --trace-ascii look even better, and make OD 0A occurances
get output as plain newlines.

AIX wants sys/select.h for the fd_set stuff in curl/multi.h, and even though
it is a bit ugly work-around to add this here, it is still a working work-
around! ;-)

Patrick Smith's contributed docs improvements for when NLST is used by
curl...

7.9.7-pre2

Added --trace-ascii support

--trace-ascii and --junk-session-cookies were added

support for ingoring session cookies added

the code for case CURLOPT_DEBUGDATA code broke the CURLOPT_STDERR one!

recent fiddling

CURLOPT_FILE and CURLOPT_INFILE have better aliases now:
CURLOPT_WRITEDATA and CURLOPT_READDATA

Added multi-post.c, based on the source file posted by Gustaf Hui

Better support for being used with the multi interface without the *fd_set()
and proper select()ing have been made.

--trace is a 7.9.7 function

added -Z/--max-redirs and --trace
changed order of a few others to keep the a-z order
