These are OS/2-specific things added to the code in the year 2000. They
were always ugly. If there's any user left, they still don't need it
done this way.

- Allow proxy_ssl to be checked for pending data even when connssl does
not yet have an SSL handle.
This change is for posterity. Currently there doesn't seem to be a code
path that will cause a pending data check when proxyssl could have
pending data and the connssl handle doesn't yet exist [1].
[1]: Recall that an https proxy connection starts out in connssl but if
the destination is also https then the proxy SSL backend data is moved
from connssl to proxyssl, which means connssl handle is temporarily
empty until an SSL handle for the destination can be created.

Closes https://github.com/curl/curl/pull/1916
Connections that are used for HTTP/1.1 Pipelining or HTTP/2 multiplexing
only get additional transfers added to them if the existing connection
is held by the same multi or easy handle. libcurl does not support doing
HTTP/2 streams in different threads using a shared connection.

For pop3/imap/smtp, added test 891 to somewhat verify the pop3
case.
For this, I enhanced the pingpong test server to be able to send back
responses with LF-only instead of always using CRLF.

Figured out while reviewing code in the libssh backend. The pointer was
checked for NULL after having been dereferenced, so we know it would
always equal true or it would've crashed.

The previous code was incorrectly following the libssh2 error detection
for libssh2_sftp_statvfs, which is not correct for libssh's sftp_statvfs.

The SFTP back-end supports asynchronous reading only, limited
to 32-bit file length. Writing is synchronous with no other
limitations.
This also brings keyboard-interactive authentication.

That also updates tests to expect the right error code
libssh2 back-end returns CURLE_SSH error if the remote file

which is sent by the libssh backend.

Absent any 'symbol map' or script to limit what gets exported, static
linking of libraries previously resulted in a libcurl with curl's and
those other symbols being (re-)exported.
This did not happen if 'versioned symbols' were enabled (which is not
the default) because then a version script is employed.
This limits exports to everything starting in 'curl_*'., which is
what "libcurl.vers" exports.
This avoids strange side-effects such as with mixing methods
from system libraries and those erroneously offered by libcurl.
Closes#2127
Originally, my idea was to allocate the two structures (or more
precisely, the connectdata structure and the four SSL backend-specific
strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so
that they all could be free()d together.
However, getting the alignment right is tricky. Too tricky.
So let's just bite the bullet and allocate the SSL backend-specific
data separately.
As a consequence, we now have to be very careful to release the memory
allocated for the SSL backend-specific data whenever we release any
connectdata.

This bit is no longer used. It is not clear what it meant for users to
"init the TLS" in a world with different TLS backends and since the
introduction of multissl, libcurl didn't properly work if inited without
this bit set.
Not a single user responded to the call for users of it:

- Align the array of ssl_backend_data on a max 32 byte boundary.
8 is likely to be ok but I went with 32 for posterity should one of
the ssl_backend_data structs change to contain a larger sized variable
in the future.
Prior to this change (since dev 70f1db3, release 7.56) the connectdata
structure was undersized by 4 bytes in 32-bit builds with ssl enabled
because long long * was mistakenly used for alignment instead of
long long, with the intention being an 8 byte boundary. Also long long
may not be an available type.
The undersized connectdata could lead to oob read/write past the end in
what was expected to be the last 4 bytes of the connection's secondary
socket https proxy ssl_backend_data struct (the secondary socket in a
connection is used by ftp, others?).

CVE-2017-8818
Bug: https://curl.haxx.se/docs/adv_2017-af0a.html
With this check present, scan-build warns that we might dereference this
point in other places where it isn't first checked for NULL. Thus, if it
*can* be NULL we have a problem on a few places. However, this pointer
should not be possible to be NULL here so I remove the check and thus
also three different scan-build warnings.
Closes#2111
* LOTS of comment updates
* explicit error for SMB shares (e.g. "file:////share/path/file")
* more strict handling of authority (i.e. "//localhost/")
* now accepts dodgy old "C:|" drive letters
* more precise handling of drive letters in and out of Windows
(especially recognising both "file:c:/" and "file:/c:/")
Closes#2110
The new API added in Linux 4.11 only requires setting a socket option
before connecting, without the whole sento() machinery.
Notably, this makes it possible to use TFO with SSL connections on Linux
as well, without the need to mess around with OpenSSL (or whatever other
SSL library) internals.
