(_WINNLS_): Drop definition and subsequent undef.
(_WINNETWK_): Ditto.
(_WINSVC_): Ditto.

(dump_sysinfo): Call RtlGetVersion rather than GetVersionEx to get
correct OS info even on Windows 8.1. Don't check return value since
RtlGetVersion never fails per MSDN. Move fetching kernel32 module
handle where it's really needed. Drop temporary comment added by
previous checkin.
* wincap.cc (wincapc::init): Rather than GetVersionEx, call
RtlGetVersion which is not crippled by missing Windows 8.1 manifest.
* wincap.h (wincapc): Change type of version to RTL_OSVERSIONINFOEXW.
Align formatting of all class members.
hints is NULL. Add a comment and set whints.ai_family explicitely to
AF_UNSPEC to follow glibc man page closely. Check flags against whints
for locality.
if fetching OSVERSIONINFOEX failed. Drop code handling unsupported
platform IDs. Add code to tweak dwMinorVersion on Windows 8.1 if no
manifest is present.
(IdnToUnicode): Define.
(FreeAddrInfoW): Define.
(GetAddrInfoW): Define.
(GetNameInfoW): Define.
* net.cc: Drop W. Richard STEVENS libgai implementation.
(cygwin_freeaddrinfo): Move code from ipv4_freeaddrinfo here. Move
definition up in file to avoid forward declaration in ga_duplist.
(ga_dup): Take addrinfoW as input. Add parameters to get IDN flags
and to set error value. Handle IDN flags and especially AI_CANONIDN.
Convert input wchar_t ai_canonname string to multibyte for output.
(ga_duplist): Add parameters to get IDN flags and to set error value
and propagate to ga_dup. Call cygwin_freeaddrinfo.
(gai_errmap): Add comments. Align error strings to GLibc. Add
EAI_IDN_ENCODE entry.
(get_ipv6_funcs): Remove.
(load_ipv6_guard): Remove.
(ipv6_inited): Remove.
(load_ipv6): Remove.
(load_ipv6_funcs): Remove.
(cygwin_getaddrinfo): Drop calling load_ipv6. Handle AI_IDN* flags.
Convert input strings to wchar_t and call GetAddrInfoW/FreeAddrInfoW.
In case hints is NULL, set default ai_flags explicitely to
AI_V4MAPPED | AI_ADDRCONFIG, as documented for Glibc. Only add AI_ALL
if AI_ADDRCONFIG is not given. Unconditionally add Windows-specific
AI_DISABLE_IDN_ENCODING to ai_flags to make IDN behaviour compatible
to Glibc even on Windows 8 and later.
(cygwin_getnameinfo): Drop calling load_ipv6. Handle NI_IDN* flags.
Call GetNameInfoW and convert returned strings from wchar_t to
multibyte.
* include/netdb.h: Add comments to describe flags and error values.
(AI_*): Define all flags using hex values for clearness.
(AI_IDN): Define.
(AI_CANONIDN): Define.
(AI_IDN_ALLOW_UNASSIGNED): Define.
(AI_IDN_USE_STD3_ASCII_RULES): Define.
(NI_*): Define all flags using hex values for clearness.
(NI_IDN): Define.
(NI_IDN_ALLOW_UNASSIGNED): Define.
(NI_IDN_USE_STD3_ASCII_RULES): Define.
(EAI_IDN_ENCODE): Define.
(dumper.exe): Link against psapi.dll.
* cygcheck.cc (_WIN32_WINNT): Define as 0x0602.
(pInternetCloseHandle): Drop pointer.
(PRODUCT_UNLICENSED): Drop definition.
(PRODUCT_PROFESSIONAL_WMC): Ditto.
(package_grep): Delete code loading wininet functions dynamically, just
call functions directly.
