Joachim Henze 845768f0a6 [0.4.9][IPHLPAPI][TCPIP][IP][LWIP][SDK][PSDK] Port back groundworks for netstat 
This fixes:
CORE-15363 'netstat TCP foreign address port is wrong'
CORE-5401 'Netstat returns ERROR_NO_DATA Pipe being closed'
CORE-5126 'UNIMPLEMENTED: iphlpapi: GetExtendedUdpTable'
even without touching the netstat binary yet.
And is mostly based on work done by Pierre Schweitzer during 0.4.11-dev'ing.

by porting back:
0.4.15-dev-6231-g a5360f542f [IPHLPAPI] Formatting only, no functional change
partially 0.4.14-dev-1425-g f540b2b20c [IPHLPAPI] GetAdaptersAddresses(): Add 1 free() in ERROR_NO_DATA case (#2526) (but leave out adding the comments in .h)

0.4.11-dev-779-g 678204790c [IPHLPAPI] Implement getNumTcpEntries() and getTcpTable() CORE-5401
----------------
Strip some DPRINTs entirely in IPHLPAPI/TCPIP in releases/0.4.7 - 0.4.10 (instead of fixing them like we did on master). Many of them had x64 issues:
This was partially *inspired* by watching the following commits:
0.4.13-dev-14-g f9a967b2ae [IPHLPAPI] Fix misc 64 bit issues (only the parts in iphlpapi_main.c with the format strings)
0.4.10-dev-409-g 0f8439aa71 [IPHLPAPI] Fix 64 bit issue, just the one within [IPHLPAPI] ifenum_reactos.c
0.4.9-dev-856-g 6c9359221c [IPHLPAPI] ipstats_reactos: Review all TRACE/WARN calls
This does not only fix the x64 incompatibilities by superseding those 3 commits but also will keep the file-sizes under control for the backports.
