NAT: G/c bogus VBOX && !NO_USE_SOCKETS code disabled in r93447. Same object code is generated.

NAT: Convert NATState::curtime from milliseconds to seconds when we assign it to libalias instance timeStamp and g/c ifdefed code to do that when link expiration time is checked. Reduces diff with original.

NAT: clean up an #ifdef in HouseKeeping() to avoid duplication of code and to make it clear that the comment that was hidden undef !VBOX still applies in VBOX case. Same object code is generated.

NAT: Fix #else /* VBOX */ comments to reflect the condition when that #else is selected. While here, add spaces inside cramped #endif /*VBOX*/ comments. Same object code is generated.

NAT: #7342: debug assertion in sofree() triggered by ftp connections. Do a minimal stop-gap fix by compiling libalias with NO_USE_SOCKETS. Two wrongs don't make a right, but this at least averts harm.

tabs

NAT: collapsing EAGAIN,EWOULDBLOCK,EINPROGRESS conditions to soIgnorableErrorCode inline function.

NAT: Zero pointer to link on link remove. (#6188)

NAT: attempt to fix #6188. libaslias marks sockets for deletion, but don't delete.

NAT:libalias: tabs.

NAT:libalias: initialization of TCP socket for constructed link.

NAT/libalias: better socket's reference count.

NAT: tabs.

NAT: libalias closes self sockets, and Slirp inform libalias in case it closes its socket.

NAT: verification that sockets always stay on right queues.

NAT: warnings [-Wunused-macros]

NAT: warnings.

NAT: logging. (vbox/#9346).

Devices: whitespace cleanup

NAT: another close() => closesocket but this time in dead code

NAT: test for >= 0 is better here

alias_db.c: consitency, use RTMemFree instead of free() on that so structure.

NAT: freeing allocated socket structure.

NAT: closing socket without confusing microsoft runtime libraries.

NAT: typo.

NAT: sockfd isn't used in VBOX.

NAT: BSD mbuf

NAT: timing to Slirp's terms

NAT: time storage corresponds to Slirp requirements, and time conversion for HouseKeeping

NAT: linalias's links expire too fast

NAT: backed 50155

NAT: libalias's links were expired too fast

NAT: bsd friendly binding

NAT: correct binding

NAT/libalias: disabling libalias socket managment

NAT: export of libalias
