libnetdriver: turn into network driver framework
The new implementation of this library provides abstractions for
network drivers, and should be used for all network drivers from now
on. It provides the following functionality:
- a function call table abstraction, hiding the details of the
datalink protocol with simple parameters;
- a state machine for sending and receiving packets, freeing the
actual driver from keeping track of pending requests;
- an abstraction for copying data from and to the network driver,
freeing the actual driver from dealing with I/O vectors while at
the same time providing a copy implementation which is more
efficient than most current driver implementations;
- a generalized implementation of zero-copy port-based I/O;
- a clearer set of policies and defaults.
While the concept is very similar to lib{block,char,fs,input}driver,
one main difference is that libnetdriver now also takes care of SEF
initialization, mainly so that aspects such as recovery policies and
live-update aspects can be changed for all network drivers in a
single place. As always, for the case that the provided message loop
is too restrictive, a set of more low-level message processing
functions is provided.
The netdriver API has been designed so as to allow alleviation of one
current protocol bottleneck: the fact that at most one send request
and one receive request may be pending at any time. Changing this
aspect will however require a significant rewrite of libnetdriver,
and possibly debugging of drivers that are not able to cope with (in
particular) queuing multiple packets for transmission at once.
Beyond that, the design of the new API is based on the current
protocol, and may be changed/extended later to allow for non-ethernet
network drivers, exposure of link status, multicast address
configuration, suspend and resume, and any other features that are in
fact long overdue.

etc/usr/rc: fix argument passing for net drivers
The expected argument name would include the instance number, which
is not only redundant in many cases (FOOETHn_n=arg.., "n" being the
instance number) and conflicted with what netconf(8) does, but some
drivers need to be able to see the arguments for all instances of its
driver type--for example, dp8390 needs to know how many earlier
instances have been configured to use PCI.

strfile. This utility is used while generating fortune database.
This patch simply sets TOOL_STRFILE to contain an absolute path.

The jump-to-start hack is not resetting global variables, resulting in
a crash after several such restarts cause an overflow in the network
table. This patch fixes that particular issue, but more similar
issues (in particular memory leaks) are bound to come up. As such this
is a stopgap measure until we can get rid of the old dhcpd altogether.
This resolves the additional issue reported in #2.

This patch adds (very limited) support for memory-mapping pages on
file systems that are mounted on the special "none" device and that
do not implement PEEK support by themselves. This includes hgfs,
vbfs, and procfs.
The solution is implemented in libvtreefs, and consists of allocating
pages, filling them with content by calling the file system's READ
functionality, passing the pages to VM, and freeing them again. A new
VM flag is used to indicate that these pages should be mapped in only
once, and thus not cached beyond their single use. This prevents
stale data from getting mapped in without the involvement of the file
system, which would be problematic on file systems where file contents
may become outdated at any time. No VM caching means no sharing and
poor performance, but mmap no longer fails on these file systems.
Compared to a libc-based approach, this patch retains the on-demand
nature of mmap. Especially tail(1) is known to map in a large file
area only to use a small portion of it.
All file systems now need to be given permission for the SETCACHEPAGE
and CLEARCACHE calls to VM.
A very basic regression test is added to test74.

This obviates the need for several file system implementations to

Fixes for problems found by running Melkor ELF fuzzing tool:
. VM: better handle case where region prealloc fails by
freeing memory that was allocated so far

peek requests, not just read

Define _NLS_PRIVATE in tools/llvm-tblgen/Makefile so that
<tools/compat/nl_types.h> will pull in <include/nl_types.h>. This is
necessary as Clang's c++/v1/locale implementation contains references
to catopen and other catalog symbols that aren't defined anywhere.
Moreover, the compiler will complain about NL_CAT_LOCALE not being
declared. The compat nl_types.h fixes these discrepancies.
However, <nl_types.h> uses __format_arg to add function attributes to
declarations. On NetBSD __format_arg(fmtarg) is defined by
<sys/cdefs.h> to be __attribute__((__format_arg__ (fmtarg))) for
briefness, but other platforms don't do that. Consequently, the build
will fail on catopen and friends function declarations because the
compiler doesn't know how to handle __format_arg(fmtarg). A fixup to
<tools/compat/nl_types.h> takes care of this, but it won't win any
beauty contest.

Read calls may be repeated by VFS if the user destination memory is
not mapped in. Devman currently assumes that all reads are
successful, and uses this to track whether EOF has been reached for
a particular event, discarding it as soon as this happens. Upon
repetition, this may result in lost events for devmand.
With this patch, devman discards events only once devmand reads the
EOF marker, which itself can never generate a user page fault. The
result is that read calls for data can be repeated safely, without
the risk of losing events in the process.

The NetBSD version is seriously broken--it is unable to match lines
against an empty pattern--and appears to be unmaintained.
The new version is the latest OpenBSD grep, with a number of MINIX-

(signed/unsigned, const) fixes to pass compilation.
Since this is not NetBSD code, move back the entire thing into
minix/usr.bin.
