Instead of using a fixed 256 byte buffer in the connectdata struct.
In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.
This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.

From within the timer callbacks. Recursive is problematic for several
reasons. They should still work, but this way the examples and the
documentation becomes simpler. I don't think we need to encourage
recursive calls.

- Split off connection shutdown procedure from Curl_disconnect into new
function conn_shutdown.
- Change the shutdown procedure to close the sockets before
disassociating the transfer.
Prior to this change the sockets were closed after disassociating the
transfer so SOCKETFUNCTION wasn't called since the transfer was already
disassociated. That likely came about from recent work started in
Jan 2019 (#3442) to separate transfers from connections.

... and remove it from the dist tarball. It has served its time, it
barely gets updated anymore and "everything curl" is now convering all
this document once tried to include, and does it more and better.
In the compressed scenario, this removes ~15K data from the binary,
which is 25% of the -M output.
It remains in the git repo for now for as long as the web site builds a
page using that as source. It renders poorly on the site (especially for
mobile users) so its not even good there.

Previously the function would edit the provided header in-place when a
semicolon is used to signify an empty header. This made it impossible to
use the same set of custom headers in multiple threads simultaneously.
This approach now makes a local copy when it needs to edit the string.

- Change the behavior of win32_init so that the required initialization
procedures are not affected by CURL_GLOBAL_WIN32 flag.
libcurl via curl_global_init supports initializing for win32 with an
optional flag CURL_GLOBAL_WIN32, which if omitted was meant to stop
Winsock initialization. It did so internally by skipping win32_init()
when that flag was set. Since then win32_init() has been expanded to
include required initialization routines that are separate from
Winsock and therefore must be called in all cases. This commit fixes
it so that CURL_GLOBAL_WIN32 only controls the optional win32
initialization (which is Winsock initialization, according to our doc).
The only users affected by this change are those that don't pass
CURL_GLOBAL_WIN32 to curl_global_init. For them this commit removes the
risk of a potential crash.

- Save the original conn->data before it's changed to the specified
data transfer for the connection check and then restore it afterwards.
This is a follow-up to 38d8e1b 2019-02-11.
History:
It was discovered a month ago that before checking whether to extract a
dead connection that that connection should be associated with a "live"
transfer for the check (ie original conn->data ignored and set to the
passed in data). A fix was landed in 54b201b which did that and also
cleared conn->data after the check. The original conn->data was not
restored, so presumably it was thought that a valid conn->data was no
longer needed.
Several days later it was discovered that a valid conn->data was needed
after the check and follow-up fix was landed in bbae24c which partially
reverted the original fix and attempted to limit the scope of when
conn->data was changed to only when pruning dead connections. In that
case conn->data was not cleared and the original conn->data not
restored.
A month later it was discovered that the original fix was somewhat
correct; a "live" transfer is needed for the check in all cases
because original conn->data could be null which could cause a bad deref
at arbitrary points in the check. A fix was landed in 38d8e1b which
expanded the scope to all cases. conn->data was not cleared and the
original conn->data not restored.
A day later it was discovered that not restoring the original conn->data
may lead to busy loops in applications that use the event interface, and
given this observation it's a pretty safe assumption that there is some
code path that still needs the original conn->data. This commit is the
follow-up fix for that, it restores the original conn->data after the
connection check.

On non-ascii platforms, the chunked hex header was measured for char code

In addition, the efective length is already known: use it.
Since the hex length can be zero, only convert if needed.
