including the windows headers. Explain why.

(TP_NUM_W_BUFS): Ditto.
(class san): Change type of _c_cnt and _w_cnt to unsigned.
* path.cc (normalize_posix_path): Guard recursion into path_conv
against tmp_pathbuf overflow. Generate normalized path in call to
path_conv. If the path is valid, replace dst with the normalized_path
from path_conv call. Add comment to explain why we're doing this.

first buffer pointer is NULL.
(tmp_pathbuf::c_get): Simplify error message.

other name changes.
(dev_console::fillin): Accommodate rename. Notice max x/y written to. Forgo
memset if GetConsoleScreenBufferInfo fails.
(fhandler_console::scroll_buffer): Accommodate rename. Don't treat y
coordinate of zero as top of screen.
(dev_console::is_fullscreen): New function.
(dev_console::scroll_window): Ditto.
(fhandler_console::clear_screen): Just scroll the screen when clearing the
screen in a state where the screen buffer is bigger than the screen.
(fhandler_console::char_command): Try harder to get 'S' and 'T' working in the
presence of a screen buffer. Use temporary 'n' variable rather than
dev_state.args[0]. Use GNU ?: shortcut method.
(cltype): New enum.
(dev_console::console_attrs): Define struct name.
(dev_console::console_attrs::set_cl_x): New function.
(dev_console::console_attrs::set_cl_y): New function.

based on enum value.

(ReadConsoleOutputWrapper): Remove coord argument since we now always use 0, 0.
Send extra arguments to region_split.
(stop_transaction): Take "trans" HANDLE by reference and set it to
NULL after closing it.
(unlink_nt): If NtOpenFile fails due to a transactional error, stop
transaction and retry NtOpenFile. Simplify check for having to call
stop_transaction.
(rename): If NtOpenFile fails due to a transactional error, stop
transaction and retry NtOpenFile in both affected cases. Simplify check
for having to call stop_transaction and add comment from unlink_nt.
flags. If the file to move to the bin has been opened casesensitive,
reopen it caseinsensitive. Explain why. Revert the default name of
the Vista-and-later recycler to mixed case for readability.
(unlink_nt): Call try_to_bin with file open flags as evaluated.
* 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.
(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.

old-style console devices when called to perform BSD flock locking.
