In some versions of VxWorks the fcntl F_GETFL/F_SETFL opcodes do not appear to be implemented, and thus it is not possible to set O_NONBLOCK mode. However, this mode is not necessarily required, it is more of a backup/failsafe. The "selectable" flag should not be dependent on whether O_NONBLOCK flag got set. This also adjust some timeouts and adds some delays to improve the reliability of network-api-test on VxWorks. The timeouts were only 10ms, and this is much too short as messages are getting written on a 9600 baud console (avg 1ms/char). A single log message can easily take 50-60ms alone.

Describe the contribution
In some versions of VxWorks the fcntl F_GETFL/F_SETFL opcodes do not appear to be implemented, and thus it is not possible
to set O_NONBLOCK mode. However, this mode is not necessarily required, it is more of a backup/failsafe.
The "selectable" flag should not be dependent on whether O_NONBLOCK flag got set.
This also adjust some timeouts and adds some delays to improve the reliability of network-api-test on VxWorks. The timeouts
were only 10ms, and this is much too short as messages are getting written on a 9600 baud console (avg 1ms/char). A single log message can easily take 50-60ms alone.
Fixes #988
Testing performed
Execute network-api-test on supported platforms (esp. VxWorks 6.9 in particular)
Expected behavior changes
Test now passes reliably.
System(s) tested on
Ubuntu 20.04 (native)
VxWorks 6.9 (MCP750)
Additional context
This also requires/depends on #992 for reliable operation. The console mutex is required to ensure that the various information messages from the client/server tasks inside network-api-test do not clobber eachother, but it also helps synchronize them too.
