Both IMAP and POP3 response characters are used internally, but when
appended to the STARTTLS denial message likely could confuse the user.

Closes https://github.com/curl/curl/pull/1203

- Format the numeric denial code as an integer instead of a character.

... when checking for a too large request.

Define _WINSOCKAPI_ blank rather than to 1 in order to match the value
used by Microsoft's winsock header files.

At least mostly, not counting // comments.

libcurl requires CURLMOPT_SOCKETFUNCTION to KEEP watching socket events
and notify back. Modify event_cb() to continue watching events when

This error code was once introduced when some library was dynamically
loaded and a funciton within said library couldn't be found.

Failure to decompress is now a write error instead of the weird
"function not found".

- Use Windows API SetFileTime to set the file time instead of utime.

Avoid utime on Windows if possible because it may apply a daylight
saving time offset to our UTC file time.

The <netinet/tcp.h> is a leftover from the past when TCP socket options
were set in this file. This include causes build issues on AIX 4.3.

Closes #1178

Fixed an old leftover use of the USE_SSLEAY define which would make a
socket get removed from the applications sockets to monitor when the
multi_socket API was used, leading to timeouts.

Bug: #1174

... as the former ones always go stale!

... and regenerated curl.1

... which the help text already implied since we switched to libidn2
from libidn in commit 9c91ec77 back in October 2016.

wolfSSL configure script relevant changes from 3.9 to 3.10:

- DES3 no longer enabled by default
- Shamir no longer enabled by default
- Extended master secret enabled by default
- RSA and ECC timing protections enabled by default

For backwards compatibility I enabled DES3 and ECC shamir config options
(ie no change from 3.9), and the other changes are included.
