[PATCH v5 0/2] MR6021: nsiproxy.sys: Use pcblist64 sysctl to enumerate TCP & UDP connections on macOS.

[Tim Clem (＠tclem)]

The handles returned by libproc (namely struct socket_info's soi_pcb)
use all 64 bits, but the ones from the pcblist sysctl are truncated
to 32. That makes find_owning_pid fail. The pcblist64 sysctl was
added in macOS 10.6 and returns handles that match those from
libproc.

There does not seem to be a MIB constant for the pcblist64 sysctls, so I'm caching the result of sysctlnametomib.
