Fixes #2128

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.

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.

This SFTP test fails with libssh back-end due to failure to verify
the peer. Disable peer verification in the test as there seems to
be the intention of the test.

Note that the libssh back-end automatically verifies the peer's
host using the default known_hosts file.

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.

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.

Uses a separate build without --enable-debug and no valgrind.

The debug option causes far too many warnings in boringssl's headers
(C++ comments, trailing commas etc).  Valgrind triggers some false
positive errors in thread-local data used by boringssl.
