primitives. load errno.scm. * netconst.scm: undefine maybe-define and maybe-define-so after use. * errno.scm: new file. * fports.c (scm_open_file): pass errno to scm_syserror_msg. * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS, SCM_FD. * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to scm_syserror_msg. * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek, scm_sys_dup): deleted: FD capability will be added to other procedures. * Remove support for the FD object type: scm_tc16_fd, scm_fd_print, scm_fd_free, fd_smob, scm_intern_fd. * (scm_open): renamed from scm_sys_open. Return a port instead of an FD object. Make the mode argument optional. * (scm_sys_create): deleted, it's just a special case of open. (scm_init_filesys): move interning of constants O_CREAT etc., here (were previously using SCM_CONST_LONG macro). Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT. don't newsmob fd. (numerous _sys_ procedures): remove gratuitous _sys_ from names. include "fports.h" and <stdio.h> (scm_stat, scm_select): don't support FD objects. * error.h: adjust scm_syserror_msg prototype. * error.c (scm_syserror_msg): take an extra argument for errno. Using the global value didn't always work, since it could be reset by procedure calls in the message or args arguments. * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined. I don't understand why the check was there (and what about the ultrix check?) * strop.c (scm_string_copy): allow shared substrings to be copied. * unif.h: corresponding change to prototypes. * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x): recognize two new optional arguments: offset and length. Allow the port argument to be an integer (file descriptor, for scsh). Include <unistd.h> for "read" prototype.
