cosmetic fix.

summary edit: mention that some options take a curl_off_t

Roland Krikava's cookies over proxy fix.

fixed linkage dll targets. (submitted by Casey O'Donnell)

added two good ideas

mention Harshal Pradhan's windows fix

Harshal Pradhan made minor syntax change to make this build with MSVC 7.1

removed the ispell-added local word, compressed the final links into a
short section

strip trailing whitespace

spell

Added "5.9 How does libcurl resolve host names?" since I wrote the text in
a mail anyway the other day.

updated with recent changes

hm

3.16 What certificates do I need with I use SSL?

my first attempt at a basic description of the certs involvede

removed trailing whitespace, indented to curl-style levels

Removed the _XOPEN_SOURCE defining again since it caused major havoc in IRIX
land with many warnings and even compiler errors due to missing structs etc

--disable-[protocol] doesn't disable tests of the specific protocol

clarify that CURLE_FTP_USER_PASSWORD_INCORRECT might in fact get returned
even if user and password are correct

include the server response in the error message when an FTP server gives
back a 530 after the password is provided, as it isn't necessary because of a
bad user name or password.

define the _XOPEN_SOURCE define in the config.h file instead, and also added a
decent quote about the define, taken from
http://www.opengroup.org/onlinepubs/007908799/xsh/compilation.html

fixed the default result for xopen and mimpure to work better

experimental code to detect mips-sgi-irix systems that build without gcc
and if so, define _XOPEN_SOURCE to 500 in an attempt to build with less
warnings (on the 64bit versions)

added several recent bindings

updated the CURLOPT_POST description after input from Alan Pinstein

Ok, setting CURLOPT_POST to 0 will now convert the request to a GET (this
remains undocumented as this is not the way we recommend)
