* 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.
(IdnToUnicode): 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.

(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.
old-style console devices when called to perform BSD flock locking.
Add a FIXME to comment and align description.
* ntdll.h (THREADINFOCLASS): Following MSDN, rename throughout from
THREAD_INFORMATION_CLASS.
* devices.cc: Regenerate.
* fhandler.h (fhandler_dev_clipboard::open): Drop declaration.
* fhandler_clipboard.cc (fhandler_dev_clipboard::dup): Drop call to
open. Set private members to 0 and call fhandler_base::dup.
(fhandler_dev_clipboard::open): Remove so that default
fhandler_base::open is used to open \Device\Null.
(set_clipboard): Drop gratuitios call to RegisterClipboardFormatW.
(fhandler_dev_clipboard::close): Call fhandler_base::close from here.
handling of membuffer. It's NULL anyway.
(fhandler_dev_clipboard::lseek): Set membuffer to NULL after freeing
it to avoid subsequent crashes when accessing invalid pointer.
\Device\Null.
* devices.cc: Regenerate.
* fhandler.h (fhandler_dev_random::open): Drop declaration.
(fhandler_dev_random::close): Ditto.
(fhandler_dev_random::crypt_gen_random): Convert to static method.
* fhandler_random.cc (fhandler_dev_random::open): Remove so that default
fhandler_base::open is used to open \Device\Null.
(fhandler_dev_random::close): Ditto.
* fhandler_socket.cc (entropy_source): Delete.
(fhandler_socket::af_local_set_secret): Remove entropy_source code and
call fhandler_dev_random::crypt_gen_random directly instead.
* devices.cc: Regenerate.
* dtable.h (struct dtable): Make fhandler_base friend, rather
than fhandler_disk_file.
* fhandler.cc (fhandler_base::open_with_arch): Create unique id.
(fhandler_base::cleanup): Call del_my_locks.
(fhandler_base::fcntl): Handle F_GETLK, F_SETLK and F_SETLKW.
* fhandler.h (fhandler_base::get_dev): Return real device number.
(fhandler_base::set_unique_id): New inline method.
(fhandler_disk_file::lock): Drop declaration.
(fhandler_disk_file::get_dev): New method, return pc.fs_serial_number.
(fhandler_dev_zero::open): Drop declaration.
* fhandler_disk_file.cc (fhandler_disk_file::close): Move
del_my_locks call to fhandler_base::open_with_arch.
(fhandler_disk_file::fcntl): Move handling of locking commands to
fhandler_base::fcntl.
(fhandler_base::open_fs): Drop call to NtAllocateLocallyUniqueId.
* fhandler_zero.cc (fhandler_dev_zero::open): Remove so that default
fhandler_base::open is used to open \Device\Null.
* flock.cc (fixup_lockf_after_exec): Finding a single fhandler is
enough here.
(fhandler_base::lock): Replace fhandler_disk_file::lock. Refuse to lock
nohandle devices. Handle read/write test using POSIX flags. Explain
why. Never fail on SEEK_CUR or SEEK_END, rather assume position 0,
just as Linux.
* net.cc (fdsock): Create unique id.
