Only download and convert the certdata to the ca-bundle.crt if Mozilla
changed the data

The Perl LWP module (which in a bit of a circular reference is used by
mk-ca-bundle.pl) is now indirectly using this script. I made this small
tweak to make it easier to automatically maintain the generated
ca-bundle.crt file in version control.

Some protocols have to call the underlying functions without regard to
what exact state the socket signals. For example even if the socket says
"readable", the send function might need to be called while uploading,
or vice versa. This is the case for libssh2 based protocols: SCP and
SFTP and we now introduce a define to set those protocols and we make
the multi interface code aware of this concept.

This is another fix to make test 582 run properly.

As a new state recently was added to the IMAP state machine it has to be
in the array of names as well as otherwise libcurl crashes when a debug
version runs...

Commit ca37692b should now hopefully make it run

For uploads we want to use the _sending_ function even when the socket
turns out readable as the underlying libssh2 sftp send function will
deal with both accordingly. This is what the cselect_bits magic is for.

Fixes test 582.

This reverts commit b8478187.

These issues are now addressed:

276 - Karl M's vc makefile patch
277 - The "Stall when uploading to sftp using multi interface"  bug
279 - curl_multi_remove_handle() crashes
280 - Marcus Sundberg's gss patch

http_negotiate_sspi.c was added to the source tree recently

Make GSS authentication work when a curl handle is reused for multiple
authenticated requests, by always setting negdata->state in
output_auth_headers().

This test case is meant to verify that the logic in commit
60172a04 actually works. This test failed for me before that
change and it works after it.

When using the multi interface and a handle using SFTP was removed very
early on, we would get a segfault due to the code assumed data was there
that hadn't yet been setup.

recvfrom in bionic (the android libc) deviates from POSIX and uses a
const in the 5th argument ("const struct sockaddr *") so the check now
tests for that as well.

Both SFTP and SCP are protocols that need to shut down stuff properly
when the connection is about to get torned down. The primary effect of
not doing this shows up as memory leaks (when using SCP or SFTP with the
multi interface).

This is one of the problems detected by test 582.

As we know how much to send, we can and should stop once we've sent that
much data as it avoids having to rely on other mechanisms to detect the
end.

This is one of the problems detected by test 582.

When using the multi_socket API to do SFTP upload, it is important that
we set a quick expire when leaving the SSH_SFTP_UPLOAD_INIT state as
there's nothing happening on the socket so there's no read or write to
wait for, but the next libssh2 API function needs to be called to get
the ball rolling.

This is one of the problems detected by test 582.

All C and H files now (should) feature the proper project curl source
code header, which includes basic info, a copyright statement and some
basic disclaimers.

Instead of using haxx.se as a fixed magic host name in lots of tests,
this is a first step to move toward the generic example.com host
instead.

... since search engines find what they think is a URL in this, they
hammer www.haxx.se on this port!

This is the modified existing files commit.

CyaSSL (available from git@github.com:cyassl/cyassl.git) has been
added to the SSL abstraction layer.

To test:
1) git CyaSSL sources
2) autoreconf -i
3) ./configure --disable-static
4) make
5) sudo make install
6) autoreconf -i
7) git curl sources (and this patch)
8) ./configure --disable-shared --with-cyassl --without-ssl --enable-debug
9) make
10) normal testing

Please send questions or comments to todd@yassl.com .

Stress that it is for client certificates and then mention that it also
works for all other SSL-based protocols apart from HTTPS and
FTPS. Namely POP3S, IMAPS and SMTPS for now.

Accidentally not included in commit 0e74e1d8

Add test 582 for uploading a file using sftp and the multi interface.

(Patch and test slightly tweaked by Daniel Stenberg)

Initially marked as disabled until it is fixed in the source.

The end-of-file #endif in rawstr.h was not correcly positioned after all
prototypes.
