a2e06edcc9 Fixes for unreliable console keepalive issue #44: 
1. Fix configure.ac tcp.h header and keepalive constant checks and report during ./configure the keepalive support that was detected (none, basic or full).

2. #include the correct tcp.h header in hstdinc.h

3. Issue warning message at build time (during make) when full keepalive support is missing or partial.

4. Report partial or missing keepalive build support via version.c "With" and "Without" messages.

5. Issue error or warning in both impl.c as well as in 'conkpalv' command/statement processing function when keepalive support is either missing or only partially supported. Same for the 2703 device 'ka=' option too.

6. Enhance set_socket_keepalive function to let the caller know not only about failures but also about partial-only successes (so they can be reported).

7. Fix the bad setsockopt call in the Linux version of the set_socket_keepalive function that was using the wrong value, which was at the heart of the problem. (Note: setsockopt was returning "success" anyway even though it had actually failed! [to accomplish anything].)

8. Introduce new get_socket_keepalive function to allow retrieval and reporting of current keepalive settings for a given socket.

9. Manually maintain socket keepalive values for Windows builds so it too can support retrieval of current values via new get_socket_keepalive function. (see comments in w32util.c "get_socket_keepalive" function!)

10. Minor HTML documentation edits.

8418ff70b6 Fix w32util clock_gettime HPC 64-bit integer overflow bug. 
The integer arithmetic calculation to convert elapsed HPC ticks to nanoseconds was multiplying by 1,000,000,000 and then dividing by HPC ticks per second, but if the elapsed HPC ticks was sufficiently large (as it is on some hardware running older versions of Windows) the multiplying by one billion would overflow the 64-bit integer variable leading to an elapsed nanoseconds value of zero causing the emulated TOD clock to stall bringing the guest and sometimes Hercules itself to a screeching halt.

This fix addresses the problem by range checking the values used in every calculation to ensure the variables used will never overflow. As an unavoidable side effect of the change the resolution of the emulated TOD clock on some systems running older versions of Windows will be reduced from nanosecond accuracy to, typically, only 10 nanosecond accuracy. This is not seen as a problem since the existing TOD/ETOD clock handling already ensures clock values are always unique ever increasing values.
