Pointless to check for non-NULL pointers that already have been dereferenced
and they have to be non-NULL long before this check.

avoid dereferencing a NULL pointer by setting a default word to lookup in case
it is missing

Better deal with NULL pointers.

Disable the SSH tests until the libssh2 bugs that causes test hangs
are sorted out.

When curl_easy_duphandle() fails because it can't get or make a connection
cache, we must make sure not to derefence the NULL pointer...

Check for a NULL easy->easy_conn in multi_getsock() since it can in fact
happen when curl_multi_remove_handle() is called.

Removed check for ftpcode being NULL, as later it is derefenced unconditionally
anyway and we can just as well rely on it being valid.

sshd might fail to start if given an unsupported configuration option.
Try to avoid this problem checking for some possible unsupported options,
and avoid using them in the configuration file.

Fixed some typos in the comments.

Resurrected old FTPS error tests 402 and 403 as 404 and 405.

Pointer "conn" dereferenced before NULL check. found by coverity.com scan

Pointer "cur_pos" dereferenced before NULL check, found by coverity.com scan.
Removed the NULL check since the pointer must be valid already.

pointless check for 'out' being non-NULL, since it was badly done and is
unnecessary - found by coverity.com scan

dead code removed, found by the coverity.com scan

Added HTTP --max-filesize tests and FTPS CCC failure test.
