62399df2c9 Add proper const keywords to sysctl(3) parameters.
The `name' and `newp' arguments can be marked const, because the buffers
they refer to are never changed. While there, perform some other
cleanups:

- Remove K&R from sysctl.c.
- Implement sysctlbyname() using sysctlnametomib() to prevent
  duplication of an undocumented kernel interface.
- Fix some whitespace nits.

It seems the prototypes are now in sync with NetBSD as well.

Empty string test gone wrong.

Testing this requires that you have a locale that has the sign string
unset but has int_n_sign_posn set (the default locale falls through to
use "()" around negative numbers which is probably another bug).

I created that setup by hand and indeed without this fix negative
numbers are put out as positive numbers (doesn't fall through to use
"-" as default indicator).

Unfixed example in nl_NL.ISO8859-1 with lc->negative_sign set to empty
string:
  strfmon(buf, sizeof(buf), "%-8i", -42.0);
==>
example2: 'EUR  42,00' 'Eu 42,00'

Fixed:
example2: 'EUR  42,00-' 'Eu 42,00-'

This file and suggested fix are identical in at least freebsd-8.
Backport might be appropriate but some expert on locales should
probably have a look at us defaulting to negative numbers in
parenthesis when LC_* is default.  That doesn't look right and is not
what other OSes are doing.

2f9f616df9 Reinstate the ptrace patch to restore the 'gp' register after calling
a function. I made a mistake in assuming that the .cprestore directive
will cause the assembler to automatically restore 'gp' after the 'jalr'.

The .cprestore directive does its magic only after 'jal' and 'bal'
instructions - not the 'jalr'.

d227440524 Fix bugs:
* Fix a race in chunk_dealloc_dss().

  * Check for allocation failure before zeroing memory in base_calloc().

Merge enhancements from a divergent version of jemalloc:

  * Convert thread-specific caching from magazines to an algorithm that is
    more tunable, and implement incremental GC.

  * Add support for medium size classes, [4KiB..32KiB], 2KiB apart by
    default.

  * Add dirty page tracking for pages within active small/medium object
    runs.  This allows malloc to track precisely which pages are in active
    use, which makes dirty page purging more effective.

  * Base maximum dirty page count on proportion of active memory.

  * Use optional zeroing in arena_chunk_alloc() to avoid needless zeroing
    of chunks.  This is useful in the context of DSS allocation, since a
    long-lived application may commonly recycle chunks.

  * Increase the default chunk size from 1MiB to 4MiB.

Remove feature:

  * Remove the dynamic rebalancing code, since thread caching reduces its
    utility.

bcc7f0f408 Remove pseudo-terminals from ttys(5).
When we had utmp(5), we had to list all the psuedo-terminals in ttys(5)
to make ttyslot(3) function properly. Now that pututxline(3) deals with
slot allocation internally (not based on TTY names), we don't need to
list all the TTYs on the system in ttys(5) to make user accounting work
properly.

This patch removes all the entries from the /etc/ttys files, but also
the pts(4) entries that were appended implicitly, which was added in
r154838.

f978ef9381 Cache failing and opened catalogs in catopen() and related functions.
Continuous catopen() calls cause 4 failig stat(2) each, which means a lot
of overhead.  It is also a good idea to keep the opened catalogs in the memory
to speed up further catopen() calls to the same catalog since these catalogs
are not big at all.  In this case, we count references and only free() the
allocated space when the reference count reaches 0.  The reads and writes to
the cache are syncronized with an rwlock when these functions are called from
a threaded program.

a7607816bf Just ignore the timestamps given to pututxline().
I've noticed many applications do a bad job at timekeeping, for several
reasons:

- Applications like screen(1) don't update time records when restoring
  the old user login record.
- Many applications only set ut_tv.tv_sec, not ut_tv.tv_usec.

This causes many problems for tools such as ac(8), which require the
timestamps to be properly ordered. This is why I've decided to let the
utmpx code obtain valid timestamps itself.

d17ad825d6 Remove comments about breaking the specification.
I've discussed this issue with the Austin Group and it will be fixed in
future revisions of the specification. The issue was that ut_line fields
weren't supposed to be valid for LOGIN_PROCESS entries, while
getutxline() would try to match these records anyway.

They also agreed on our way of implementing pututxline() without
getutxid() (which other operating systems also do), but unfortunately
they disagreed with our way of replacing DEAD_PROCESS entries, which is
a pity. The current specification allows the utmpx database to become
infinitely big over time.

26f87cc6ff Revert r202447 by re-exposing the old uname(3) function.
It makes hardly any sense to expose a symbol which should only be
provided for binary compatibility, but it seems we don't have a lot of
choice here. There are many autoconf scripts out there that try to
create a binary that links against the old symbol to see whether
uname(3) is present. These scripts fail to detect uname(3) now.

It should be noted that the behaviour we implement is not against the
standards:

| The following shall be declared as a function and may also be defined
| as a macro:
|
| int uname(struct utsname *);

dcdafd0e92 a) Use strcoll() in opendir() and alphasort() as POSIX 2008 requires.
It also matches now how our 'ls' works for years.

b) Remove comment expressed 2 fears:
 1) One just simple describe how strcoll() works in _any_ context,
 not for directories only. Are we plan to remove strcoll() from everything
 just because it is little more complex than strcmp()? I doubt, and
 directories give nothing different here. Moreover, strcoll() used
 in 'ls' for years and nobody complaints yet.

 2) Plain wrong statement about undefined strcoll() behaviour. strcoll()
 always gives predictable results, falling back to strcmp() on any
 trouble, see strcoll(3).

No objections from -current list discussion.
