/* Function prototypes. */
Started select() implementation. Added interface to select() for pipes (also named pipes), and select() stubs for regular files. Added timer library in FS that select() is the first customer of. This is unfinished, but committed anyway to get a new release out to Al and testers.

Limited support for nested FS->VFS requests during VFS->FS call. - Changed VFS-FS protocol to only store OK or negative error code in m_type field of reply messages. - Changed VFS to treat nonzero positive replies from FS as requests. - Added backwards compatibility to VFS and MFS. No protection of global data structures is provided in VFS, so many VFS calls cannot be made safely by FS servers during many FS calls. Use with caution (or, preferably, not at all).

Implementation of truncate(), ftruncate() and the F_FREESP fcntl(). Implemented by changing write_map to accept a WMAP_FREE flag. In that case, it doesn't update the datablock (creating indirect zones as necessary) pointer, but it frees the datablock if present. Also it frees the single and double indirect blocks if unused. This makes the implementation of truncate_inode() simpler. truncate_inode() now accepts a truncation length which makes implementing truncate() and ftruncate() simple. This also allowed implementing the F_FREESP fcntl().

Merge of minix-vmd symlink code. . new_node() now returns inode of parent dir as argument that has to be put_node()d again by the caller of new_node(). it can also return the name of the last component as last_dir() did. . advance() takes a pointer to a pointer of an inode as the parent now. This parent can change, in which case the old one is put_node()d and a new one is put there. . eat_path() replaced by more flexible parse_path() . last_dir() replaced by call to parse_path(). . do_slink(), do_readlink(), do_lstat() and slink_traverse() added. Also added some truncate()/ftruncate()-introduction related changes. (e.g. renamed truncate() to truncate_inode().)

endpoint-aware conversion of servers. 'who', indicating caller number in pm and fs and some other servers, has been removed in favour of 'who_e' (endpoint) and 'who_p' (proc nr.). In both PM and FS, isokendpt() convert endpoints to process slot numbers, returning OK if it was a valid and consistent endpoint number. okendpt() does the same but panic()s if it doesn't succeed. (In PM, this is pm_isok..) pm and fs keep their own records of process endpoints in their proc tables, which are needed to make kernel calls about those processes. message field names have changed. fs drivers are endpoints. fs now doesn't try to get out of driver deadlock, as the protocol isn't supposed to let that happen any more. (A warning is printed if ELOCKED is detected though.) fproc[].fp_task (indicating which driver the process is suspended on) became an int. PM and FS now get endpoint numbers of initial boot processes from the kernel. These happen to be the same as the old proc numbers, to let user processes reach them with the old numbers, but FS and PM don't know that. All new processes after INIT, even after the generation number wraps around, get endpoint numbers with generation 1 and higher, so the first instances of the boot processes are the only processes ever to have endpoint numbers in the old proc number range. More return code checks of sys_* functions have been added. IS has become endpoint-aware. Ditched the 'text' and 'data' fields in the kernel dump (which show locations, not sizes, so aren't terribly useful) in favour of the endpoint number. Proc number is still visible. Some other dumps (e.g. dmap, rs) show endpoint numbers now too which got the formatting changed. PM reading segments using rw_seg() has changed - it uses other fields in the message now instead of encoding the segment and process number and fd in the fd field. For that it uses _read_pm() and _write_pm() which to _taskcall()s directly in pm/misc.c. PM now sys_exit()s itself on panic(), instead of sys_abort(). RS also talks in endpoints instead of process numbers.
