hurd: clean fd and port on thread cancel
HURD_*PORT_USE link fd and port with a stack-stored structure, so on thread cancel we need to cleanup this. * hurd/fd-cleanup.c: New file. * hurd/port-cleanup.c (_hurd_port_use_cleanup): New function. * hurd/Makefile (routines): Add fd-cleanup. * sysdeps/hurd/include/hurd.h (__USEPORT_CANCEL): New macro. * sysdeps/hurd/include/hurd/fd.h (_hurd_fd_port_use_data): New structure. (_hurd_fd_port_use_cleanup): New prototype. (HURD_DPORT_USE_CANCEL, HURD_FD_PORT_USE_CANCEL): New macros. * sysdeps/hurd/include/hurd/port.h (_hurd_port_use_data): New structure. (_hurd_port_use_cleanup): New prototype. (HURD_PORT_USE_CANCEL): New macro. * hurd/hurd/fd.h (HURD_FD_PORT_USE): Also refer to HURD_FD_PORT_USE_CANCEL. * hurd/hurd.h (__USEPORT): Also refer to __USEPORT_CANCEL. * hurd/hurd/port.h (HURD_PORT_USE): Also refer to HURD_PORT_USE_CANCEL. * hurd/fd-read.c (_hurd_fd_read): Call HURD_FD_PORT_USE_CANCEL instead of HURD_FD_PORT_USE. * hurd/fd-write.c (_hurd_fd_write): Likewise. * sysdeps/mach/hurd/send.c (__send): Call HURD_DPORT_USE_CANCEL instead of HURD_DPORT_USE. * sysdeps/mach/hurd/sendmsg.c (__libc_sendmsg): Likewise. * sysdeps/mach/hurd/sendto.c (__sendto): Likewise. * sysdeps/mach/hurd/recv.c (__recv): Likewise. * sysdeps/mach/hurd/recvfrom.c (__recvfrom): Likewise. * sysdeps/mach/hurd/recvmsg.c (__libc_recvmsg): Call __USEPORT_CANCEL instead of __USEPORT, and HURD_DPORT_USE_CANCEL instead of HURD_DPORT_USE.
