I've done this blindly, and the last piece that works with ares
should possibly be done differently now that c-ares isn't a
subtree within the curl tree anymore...

Prefixing the FTP quote commands with an asterisk really only
worked for the postquote actions. This is now fixed and test case
227 has been extended to verify.

Matt Wixson found and fixed a bug in the SCP/SFTP area where the
code treated a 0 return code from libssh2 to be the same as
EAGAIN while in reality it isn't. The problem caused a hang in
SFTP transfers from a MessageWay server.

using int is not fine on 64bit systems

strlen() returns size_t, but ssh libraries are wanting 'unsigned int'.  Add
explicit casts and use _ex versions of the ssh library calls.

Use ssize_t instead of int for the Curl_smtp_escape_eob nread
argument.

If you pass a URL to pop3 that does not contain a message ID as
part of the URL, it will currently ask for 'INBOX' which just
causes the pop3 server to return an error.

The change makes libcurl treat en empty message ID as a request
for LIST (list of pop3 message IDs).  User's code could then
parse this and download individual messages as desired.

My first instinct was to run the test script within the checked out
repository.  This small change to the script allows that to work as
expected.

Ben Greear brought a patch that from now on allows all protocols
to specify name and user within the URL, in the same manner HTTP
and FTP have been allowed to in the past - although far from all
of the libcurl supported protocols actually have that feature in
their URL definition spec.

all used while running tests

This gives a smoother rate limitation performance by using
sub-second pauses and also taking the buffer sizes into
account.

TFTP is not a protocol that uses close actions so it should
not be set in that bitmask!

The backtick command which extracts 'git log' lines come with a
newline, so chomp the newline before calling logit(), as the logit
function adds a newline by itself.

'git log --oneline' is a relatively recent Git function. It is
documented to be the same as 'git log --pretty=oneline --abbrev-commit',
so use that instead. It works all the way back to Git 1.5.0.

since c-ares no longer embedded, we must not touch such files
anymore
