are set before recursing.
* Makefile.in: Regenerate.
(lutimes): Export.
* times.cc (utimes_worker): Created from utimes, add nofollow flag
to implement utimes and lutimes.

cygthread to handle extra argument, throughout.

(cygthread::stub): Use callfunc to invoke thread func to allow potentially
allocating stack memory which will be returned.
(cygthread::simplestub): Ditto.
(cygthread::cygthread): Accept arglen argument. Reset ev here prior to
activating thread. Wait for ev after activating thread if we're copying
contents to the thread. Wait until the end before setting h, to allow thread
synchronization.
(cygthread::release): Don't reset ev here. Rely on that happening the next
time the thread is activated.
* pinfo.h (commune_process): Rename declaration from _pinfo::commune_process.
* pinfo.cc (commune_process): Ditto for definition. Modify slightly to allow
running as a separate cygthread.
* sigproc.cc (child_info::sync): Always wait for both subproc_ready and any
hProcess if we have a cygwin parent.
(talktome): Change argument to be a pointer to siginfo_t. Contiguously
allocate whole siginfo_t structure + any needed extra for eventual passing to
commune_process thread.

(convert_ws1_ip_optname): New static function to convert Winsock1
IPPROTO_IP option values into Winsock2 IPPROTO_IP option values.

of optname. For "old" applications, convert optname from Winsock1
to Winsock2 values before using them. Add comment to describe the
IP_TOS weirdness on W2K and above.
(cygwin_getsockopt): Remove wrong and incomplete cleartext printing
of optname. For "old" applications, convert optname from Winsock1
to Winsock2 values before using them.

Keep Winsock1 values for Cygwin internal purposes.
* include/cygwin/version.h: Bump API minor version.
(CYGWIN_VERSION_CHECK_FOR_USING_ANCIENT_MSGHDR): Define to check for
applications using old struct msghdr.
(CYGWIN_VERSION_CHECK_FOR_USING_WINSOCK1_VALUES): Define to check for
applications using old Winsock1 IPPROTO_IP values.
