Daniel Stenberg 2d7c79af76 tcpconnect: follow-up commit after b998d95b
As I modified conn->bits.tcpconnect to become an array that holds one
bool for each potential connection all uses of that struct field must
index it correctly.

Daniel Stenberg 13b64d7558 protocols: use CURLPROTO_ internally
The PROT_* set of internal defines for the protocols is no longer
used. We now use the same bits internally as we have defined in the
public header using the CURLPROTO_ prefix. This is for simplicity and
because the PROT_* prefix was already used duplicated internally for a
set of KRB4 values.

The PROTOPT_* defines were moved up to just below the struct definition
within which they are used.

Daniel Stenberg 8831000bc0 protocol handler: added flags field
The protocol handler struct got a 'flags' field for special information
and characteristics of the given protocol.

This now enables us to move away central protocol information such as
CLOSEACTION and DUALCHANNEL from single defines in a central place, out
to each protocol's definition. It also made us stop abusing the protocol
field for other info than the protocol, and we could start cleaning up
other protocol-specific things by adding flags bits to set in the
handler struct.

The "protocol" field connectdata struct was removed as well and the code
now refers directly to the conn->handler->protocol field instead. To
make things work properly, the code now always store a conn->given
pointer that points out the original handler struct so that the code can
learn details from the original protocol even if conn->handler is
modified along the way - for example when switching to go over a HTTP
proxy.

Daniel Stenberg 3eac14b43c SSH: add protocol lock direction
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.

Daniel Stenberg ca37692bf4 ssh_statemach_act: set cselect for sftp upload
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.

Daniel Stenberg 60172a0446 SFTP: gracefully handle shutdown early
When using the multi interface and a handle using SFTP was removed very

Daniel Stenberg cccba72920 sftp upload: expire to advance state machine
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.

We cannot assume that PATH_MAX will be enough for the remote path name

Daniel Stenberg 1ad5764feb SFTP: make pwd output result to header callback
Sending "pwd" as a QUOTE command only sent the reply to the
DEBUGFUNCTION. Now it also sends an FTP-like header to the header
callback to allow similar operations as with FTP, and apps can re-use
the same parser.

Kamil Dudka 5c7c9a768d url: provide dead_connection flag in Curl_handler::disconnect
It helps to prevent a hangup with some FTP servers in case idle session
timeout has exceeded.  But it may be useful also for other protocols
that send any quit message on disconnect.  Currently used by FTP, POP3,
IMAP and SMTP.

Daniel Stenberg e214cd4a73 SSH: use libssh2_session_handshake()
In libssh2 1.2.8, libssh2_session_handshake() replaces
libssh2_session_startup() to fix the previous portability problem with
the socket type that was too small for win64 and thus easily could cause
crashes and more.

Daniel Stenberg 5997f54a71 SSH: avoid using the libssh2_ prefix
It is a bad idea to use the public prefix used by another library and
now we realize that libssh2 introduces a symbol in the upcoming version
1.2.8 that conflicts with our static function named libssh2_free.

Daniel Stenberg 51b8d30dc4 SFTP: more ignoring negative file sizes
As the change in 5f0ae7a062 added a precaution against negative
file sizes that for some reason managed to get returned, this change now
introduces the same check at the second place in the code where the file
size from the libssh2 stat call is used.

This check might not be suitable for a 32 bit curl_off_t, but libssh2.h
assumes long long to work and to be 64 bit so I believe such a small
curl_off_t will be very unlikely to occur in the wild.

Daniel Stenberg 5f0ae7a062 SFTP: avoid downloading negative sizes!
It is still not clarified exactly why this happens, but libssh2
sometimes report a negative file size for the remote SFTP file and that
deeply confuses libcurl (or crashes it) so this precaution is added to
avoid badness.

Daniel Stenberg 684830cb2a SSH: corrected the inability to respect the timeout
Jason McDonald posted bug report #3006786 when he found that the
SFTP code didn't timeout properly in several places in the code
even if a timeout was set properly.

Based on his suggested patch, I wrote a different implementation
that I think addressed the issue better and also uses the connect
timeout for the initial part of the SSH/SFTP done during the
"protocol connect" phase.

Howard Chu bc8fc9803f sendrecv: make them two pairs of send/recv to properly deal with FTPS
FTP(S) use two connections that can be set to different recv and
send functions independently, so by introducing recv+send pairs
in the same manner we already have sockets/connections we can
work with FTPS fine.

This commit fixes the FTPS regression introduced in change d64bd82.

Howard Chu d64bd82bdc sendrecv: split the I/O handling into private handler
Howard Chu brought the bulk work of this patch that properly
moves out the sending and recving of data to the parts of the
code that are properly responsible for the various ways of doing
so.

Daniel Stenberg assisted with polishing a few bits and fixed some
minor flaws in the original patch.

Another upside of this patch is that we now abuse CURLcodes less
with the "magic" -1 return codes and instead use CURLE_AGAIN more
consistently.
