error codes. Always refuse non "user." EAs for Linux compatibility
and return EOPNOTSUPP. Fix handling of empty (== non-existant) EAs.
Always prepend "user." prefix to EA names.
(write_ea): Try to open file first to have more sensible error codes.
Always refuse non "user." EAs for Linux compatibility and return
EOPNOTSUPP. Delay skipping "user." prefix until after potential call
to read_ea.

(dtable::fixup_before_fork): New function.
(dtable::fixup_before_exec): New function.

declarations for above new functions.
(dtable::dec_need_fixup_before): New inline method.
(dtable::inc_need_fixup_before): New inline method.
(dtable::need_fixup_before): New inline method.
* fhandler.h (fhandler_base::fixup_before_fork_exec): New virtual
method.
(fhandler_base::need_fixup_before): New virtual method.
(class fhandler_socket): Add member prot_info_ptr.
(fhandler_socket::init_fixup_before): Declare.
(fhandler_socket::need_fixup_before): New inline method.
(fhandler_socket::fixup_before_fork_exec): Declare.
(fhandler_socket::fixup_after_exec): Declare.
* fhandler_socket.cc (fhandler_socket::fhandler_socket): Initialize
prot_info_ptr to NULL.
(fhandler_socket::~fhandler_socket): Free prot_info_ptr conditionally.
(fhandler_socket::init_fixup_before): New method.
(fhandler_socket::fixup_before_fork_exec): Ditto.
(fhandler_socket::fixup_after_fork): Use WSASocketW to duplicate
socket if necessary.
(fhandler_socket::fixup_after_exec): New method.
(fhandler_socket::dup): Use fixup_before_fork_exec/fixup_after_fork
to duplicate socket if necessary.
* fork.cc (frok::parent): Start child suspended if some fhandler
needs fixup before fork. If so, call dtable::fixup_before_fork after
CreateProcess and resume child.
* net.cc (fdsock): Try to find out if socket needs fixup before and
initialize socket accordingly. Add HUGE comment to explain what happens
and why.
* spawn.cc (spawn_guts): Start child suspended if some fhandler needs
fixup before exec. If so, call dtable::fixup_before_exec after
CreateProcess.
get_object_attr.
* fhandler_mailslot.cc (fhandler_mailslot::get_object_attr): Implement.
(fhandler_mailslot::open): Replace calls to path_conv::get_object_attr
with calls to fhandler_mailslot::get_object_attr.
(main): Don't reuse local variables confusingly. Don't print any file
information if acl() fails. Improve error message. Always print a
trailing empty line. Set return code to 2 if accessing some file fails.
SubstituteName for volume string to recognize volume mount points.
Reuse subst when calling sys_wcstombs.
* syscalls.cc (rename): Set errno to EBUSY when trying to rename
volume mount points. Explain why.
(ro_u_sys): Ditto.
* syscalls.cc (nt_path_has_suffix): Replace with ...
(nt_path_has_executable_suffix): New function checking for explicit
executable suffixes.
(rename): Call nt_path_has_executable_suffix instead of
nt_path_has_suffix. Check oldpath for nt_path_has_executable_suffix
as well to set old_explicit_suffix.
Check cygwin_internal for returning 0 rather than for != 0.
(transport_layer_pipes::accept): Add debug output.
(transport_layer_pipes::connect): Ditto.
(load_cygwin): Fetch cygwin DLL path and store in cygwin_dll_path.
* strace.cc: Full ditto.
* path.cc (read_mounts): First use the path stored in cygwin_dll_path,
if available. Then fall back to fetching own path. Add comment.
Drop printing warnings since they look funny in strace output.
