big last-beta (?) cleanup commit

The installed header files were moved from this to include/curl/Makefile.am

added to enable include file install

generated from the newly edited getdate.y that now supports a thread-safe
localtime() call

made urlfree static, added (void) in front of one of the SSL calls. I did
these changes when trying to run lclint on the curl code.

Replacing one of the internal headers with one that has no contents will now
completely disable that header to get sent.

added localtime_r()

for install and more

libtool stuff added

Added two libtool files, is ltmain.sh really necessary?

updated my email

Added [:port] to the -x description for --help

clear the httproxy bit on cleanup if the allocproxy bit was set

corrected the Host: header's port number

ASCII FTP download
-F improvements
FTP response timeouts
HTTP user+password to same host only
libtool

another day, another contributor

removed libtool, added pointer to the sourceforge task list

Added docs/Makefile*

libtool adjustments

they're generated, they don't belong here

Added Torsten Foertsch's changes to the -F description and his name to the
list of contributors.

uses the new curl_close function to clean up the http-specific auth_host

Added http_close()

uses auth_host to only send user+password to that particular site, usable if
Location: following takes "us" to other servers that should not get the
user and password

set a bit when a Location: is followed to allow code to act differently
on those occations
