ftps test case data

slightly "hackish" approach to disable SSL during download if the connection
is a FTPS connection as the data transfer is then done unencrypted!

this should not set a SSL path to LDFLAGS or CPPFLAGS unless it really needs
to

added some, removed some, moved around some.

nicer OpenSSL header check

our internal strlcat() is now named Curl_strlcat()

strlcat() is now Curl_strlcat() instead to prevent collisions when used with
other libs

strlcpy() turned static

Added #define CURLE_ALREADY_COMPLETE to not break compiles that use that
symbol, but libcurl will not return this ever

added pointer to the examples/getinmemory.c source code for paragraph
5.2 "How can I receive all data into a large memory chunk?"

Added getinmemory.c

this might actually compile too...

an example on how you can use the write callback to receive data in a memory
chunk

We need -lpthread for the pthread example

corrected

Added Pawel A. Gajda

Pawel A. Gajda fixed resumed transfers on persistent connections

Added the first https test: 300

pid files fixes, ftp server already-running-but-no-control check

Jun-ichiro itojun Hagino fixed FTP PORT for IPv6-enabled libcurl

added a pointer to the download web page

Added tons of comments all over

multiple transfer path fixes, location fixes, resume download changes,
ssl peer verify fixes and more

CURLE_ALREADY_COMPLETE is removed
CURLE_SSL_PEER_CERTIFICATE is added

Uses the Curl_SSLConnect() according to the new return type
