or a symlink to a regular file. Previously, symlinking to /dev/null
would cause less to trash /dev/null if run with sufficient privileges,
as seen in PR misc/42237.
While the official way to disable .lesshst is to set an environment
variable, that is problematic in some cases, such as single-user mode.
A safer way to prevent even an unpatched less from writing anything
out is to mkdir ~/.lesshst.
for mips64 to build this with MLIBDIR set to o32
- make mips64 ldd call elf32_compat_ldd as well
- make mips64 elf64 set MLIBDIR to 64
- don't need ld.elf_so's Makefile.ld32 files anymore (they are going away
soon anyway)
tested on amd64 and sparc64, and an earlier version tested on mips64.
dump.c includes misc.h but misc.h is generated on-the-fly.
Note that dump.c is out of the makeerrnos.sh -> misc.[ch] generation rule
now. This prevents ktruss from being unnecessarily rebuilt in rescue/.

This is a temporary fix to allow pullups to existing, supported versions
of NetBSD. I will follow up with a version for current using the new
getline function.

and Darwin 10.2.0.
This should fix one of the cross-builds under FreeBSD as reported by
Rhialto on the "current-users" mailing list.
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Reduces the amount of data written to temporary files.
The 3-level stack has to do a simple reduce after 4352 input files, for
a normal file sort this is 35GB of data or about 500 million records.
This needs about 50 open fd's - which should be ok.
Clearly the merge sort could process more input files in one go - speeding
up the sort, but at some point the number of input files would exceed
whatever limit was applied.
for substitution patterns. This (perhaps coupled with the
new handling of .for variables in ${:U<value>...) caused interesting
results for lines like:
.for file in ${LIST}
for-subst: ${file:S;^;${here}/;g}
add a unit-test to keep an eye on this.
Split the merge sort so that fsort() can pass the 'FILE *' of the temporary
files to be merged into the merge code.
Don't rely on realloc() not moving the end address of a buffer!
Rework merge sort so that it sorts pointers to 'struct mfile' and only
copies about sort record descriptors.
No functional change intended.
Pfsync interface exposes change in the pf(4) over a pseudo-interface, and can
be used to synchronise different pf.

This commit mostly adds code written by Claudio Jeker for OpenBSD to
support sysctl in the interface printing parts (-i, -I, -w). The port has
been ported to NetBSD with tiny adjustments -- of course all bugs etc.
are mine.
Also add and document a -X flag to force sysctl usage. The documentation
notes this flag may be removed at any time and its presence should not be
relied on.
Some misc. comments/#ifdef changes/code snippet moves as well.
Please note that no functionality should change as the routing and
interface printing code is still not fully supported.

This frees a byte value to use for 'end of key' (to correctly sort
short keys) while still having a weight assigned to the field sep.
(Unless -t is given, the field sep is in the field data.)
Do reverse sorts by writing the output file in reverse order (rather
than reversing the sort - apart from merges).
All key compares are now unweighted.
For 'sort -u' mark duplicates keys during the sort and don't write
to the output.
Use -S to mean a posix sort - where equal keys are sorted using the
raw record (rather than being kept in the original order).
For 'sort -f' (no keys) generate a key of the folded data (as for -n
-i and -d), simplifies the code and allows a 'posix' sort.
Use .MAKE.LEVEL to track recursion.
The first instance of make will have .MAKE.LEVEL 0, which
can be handy for excluding rules which should not apply
in a sub-make.
gmake and freebsd's make have a similar mechanism, but each
uses a different variable to track it. Since we cannot be
compatible with both, we allow the makefiles to cope if they want
by handling the export of .MAKE.LEVEL+1 in Var_Set().
an array of 'RECHEADER *' and remove all the crappy stuff that backed up
by REC_DATA_OFFSET (etc).
Also change radix_sort() to return the number of elements, soon to be used
to drop duplicate keys (for sort -u).
Currently unchanged apart from the deletion of the 'unstable' version and
other unneeded code.
Use fldtab[0]. not fldtab-> when we are referring to the global info
in the 0th entry to emphasise that this entry is different.
fldtab[0].weights is only needed in the SINGL_FLD case - so set it there.
Re-indent a big 'if' is setfield() so that the line breaks match the
logic - which looks dubious now!
Note that -H is now ignored.
Move -S and -s (and -H) to the first list of options since they are
global ones, not ones that override the ordering rules.
as if part of the data.
This is a bit fubar since we need a value than sorts before any byte value
as a key field separator - so need 257 byte values (since radixsort() doesn't
take a length for each record).
For now map '\t' to 0x01 and hope no one will notice!
