Added check of the WSASend result, as reported in #973.
Given that ::send(...) wan not observed to fail on Linux, adding a common ::select(...) call for both Windows and Linux might decrease the performance.
This PR uses Windows OverlappedIO API to wait for WSASend to succeed.

Fixes #973.
Closes #974 (replaces).

TODO

  • Retest.

a0cf944 
* [core] Fix crypto mode auto for listener sender (Haivision#2711).


Co-authored-by: oviano <ovcollyer@mac.com>

* [build] Upgraded CI: ubuntu to version 20.04 (Haivision#2682).

* [docs] Added the link for registration in slack to the getting started table (Haivision#2721).

* [core] Fixed FEC Emergency resize crash (Haivision#2717).

Fixed minimum history condition.

* [core] Fixed various compiler warnings on various platforms (Haivision#2679).

* [core] Minor fix of variable shadowing.

* [tests] Minor fix of variable shadowing.

* [build] Add -Wshadow=local to CMake build flags.
Supported since GCC 7.0.

* [core] Correct remaining endianness issues

Fixes the last two remaining test failures on big-endian.  These
operations were all already no-ops on little-endian, and unnecessarily
byteswapped the IP addresses on big-endian.

Closes: Haivision#2697

* [docs] Minor updates to AEAD docs plus changed v1.6.0 to 1.5.2 in some files

* [build] Fix downversioning of _WIN32_WINNT (Haivision#2754).

* [core] Fixed unhandled error in haicrypt (Haivision#2685).

* [core] Use overlapped WSASendTo to avoid loss in UDP sending (Haivision#2632).

* [core] Add volatile keyword to asm block in rdtsc (Haivision#2759).

* [core] Fixed srctime from closing socket was mistakenly cleared

* [core] Fixed group read-ready epoll events.

* [core] Removed unused CUDTGroup::m_Positions.

* [core] Perf improvement of group reading.

* [core] Fixed RCV buffer initialization in Rendezvous.

* [docs] Updating the explicit information for binding to IPv6 wildcard (Haivision#2765).

* [tests] Added custom main with transparent parameters for tests (Haivision#2681).

* [core] Fix memory leak when can't buffer a HS packet (Haivision#2757).

* [core] Refactor CRcvQueue::storePkt(..) for better resource management (Haivision#2775).

* [core] Fix hang up on not enough space in the RCV buffer (Haivision#2745).

When there is space available in the receiving buffer after it is full,
send an ack to allow the sender to resume transmission.
Reschedule sending if ACK decreases the flight span after sending is congested.

* [core] fix tsbpd() may deadlock with processCtrlShutdown()

* [core] Slightly optimize the RCV drop by message number (Haivision#2686).

Some minor improvements of logs and comments.

* [core] Rejection not undertaken in rendezvous after KMX failure (Haivision#2692).

* [core] Fix: In rendezvous when processing resulted in ACCEPT it was still sending rejection

* [core] Minor code clean up in CRateEstimator.

* [core] Initialize ISN and PeerISN in CUDT.

* [core] Drop unencrypted packets in GCM mode.

* [apps] Fix the build for target without IP_ADD_SOURCE_MEMBERSHIP (Haivision#2779).

* [core] Added maximum BW limit for retransmissions (Haivision#2714).

* [API] SRT version raised to 1.5.3.

* [apps] Fixed conditional IP_ADD_SOURCE_MEMBERSHIP in testmedia (Haivision#2780).

* [core] Fixed SRT_ATTR_REQUIRES use.

The header file access_control.h was added to the source tree
at some point but was not added to the Windows installer.
