Closes #105

Resolve "Cleanup platform.h for stuff not exposed to the headers"

Closes #525

See merge request isc-projects/bind9!756

5031.   [cleanup]       Various defines in platform.h has been either dropped
                        if always or never triggered on supported platforms
                        or replaced with config.h equivalents if the defines
                        didn't have any impact on public headers.  Workarounds
                        for LinuxThreads have been removed because NPTL is
                        available since Linux kernel 2.6.0.

Assume socklen_t is always available on all supported platforms (except on Windows where it is typedefed to int32_t)
