Ben Gras 2fe8fb192f Full switch to clang/ELF. Drop ack. Simplify.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

	. drop boot monitor -> allowing dropping ack support
	. facility to copy ELF boot files to /boot so that old boot monitor
	  can still boot fairly easily, see UPDATING
	. no more ack-format libraries -> single-case libraries
	. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
	. drop several ack toolchain commands, but not all support
	  commands (e.g. aal is gone but acksize is not yet).
	. a few libc files moved to netbsd libc dir
	. new /bin/date as minix date used code in libc/
	. test compile fix
	. harmonize includes
	. /usr/lib is no longer special: without ack, /usr/lib plays no
	  kind of special bootstrapping role any more and bootstrapping
	  is done exclusively through packages, so releases depend even
	  less on the state of the machine making them now.
	. rename nbsd_lib* to lib*
	. reduce mtree

.In rpc/rpc.h
.Ft struct rpcent *
.Fn getrpcent void
.Ft struct rpcent *

.Sh DESCRIPTION
.Fn getrpcent ,
.Fn getrpcbyname ,
and
.Fn getrpcbynumber ,
each return a pointer to an object with the
following structure
containing the broken-out
fields of a line in the rpc program number data base,
.Pa /etc/rpc :
.Bd -literal -offset indent
struct rpcent {
char *r_name; /* name of server for this rpc program */
char **r_aliases; /* alias list */
long r_number; /* rpc program number */
};
.Ed
.Pp
The members of this structure are:
.Bl -tag -width r_aliases -offset indent
.It r_name
The name of the server for this rpc program.
.It r_aliases
A zero terminated list of alternative names for the rpc program.
.It r_number
The rpc program number for this service.
.El
.Pp
.Fn getrpcent
reads the next line of the file, opening the file if necessary.
.Pp
.Fn setrpcent
opens and rewinds the file.
If the
.Fa stayopen
flag is non-zero,
the net data base will not be closed after each call to
.Fn getrpcent
(either directly, or indirectly through one of
the other
.Dq getrpc
calls).
.Pp
.Fn endrpcent
closes the file.
.Pp
.Fn getrpcbyname
and
.Fn getrpcbynumber
sequentially search from the beginning
of the file until a matching rpc program name or
program number is found, or until end-of-file is encountered.
.Sh FILES

A

or error.
