db1ca87b7d Fix for missing /usr/games in root's PATH
After importing the default environment from NetBSD, we discovered that
it doesn't contain /usr/games, which is required for the commands
strfile. This utility is used while generating fortune database.

This patch simply sets TOOL_STRFILE to contain an absolute path.

aa4ee93d43 dhcpd: don't crash so easily
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.

e321f65582 libfsdriver: support mmap on FSes with no device
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may become outdated at any time.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.

f53651de01 VM,MFS: better handling of some exceptional cases
Fix for problems reported by Alejandro Hernández:
	. VM unmap: handle case where there is no nextvr

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
	. MFS fs_readwrite: EOF check should happen for read and
	  peek requests, not just read

This fixes #4.

10b559663e buildsystem: fix build errors for x86 on OSX
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.

10b1b4ee12 devman: allow multiple event read calls up to EOF
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.

against an empty pattern--and appears to be unmaintained.

The new version is the latest OpenBSD grep, with a number of MINIX-

Since this is not NetBSD code, move back the entire thing into
minix/usr.bin.
