4af9918bc0 Import OpenBSD's sysctl hardware sensors framework.
This commit includes the following core components:

 * sample configuration file for sensorsd
 * rc(8) script and glue code for sensorsd(8)
 * sysctl(3) doc fixes for CTL_HW tree
 * sysctl(3) documentation for hardware sensors
 * sysctl(8) documentation for hardware sensors
 * support for the sensor structure for sysctl(8)
 * rc.conf(5) documentation for starting sensorsd(8)
 * sensor_attach(9) et al documentation
 * /sys/kern/kern_sensors.c
   o sensor_attach(9) API for drivers to register ksensors
   o sensor_task_register(9) API for the update task
   o sysctl(3) glue code
   o hw.sensors shadow tree for sysctl(8) internal magic
 * <sys/sensors.h>
 * HW_SENSORS definition for <sys/sysctl.h>
 * sensors display for systat(1), including documentation
 * sensorsd(8) and all applicable documentation

The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and  -current as of today.

All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`.

a5038f060d The problem is: currently our single byte ctype(3) functions are broken
for wide characters locales in the argument range >= 0x80 - they may
return false positives.

Example 1: for UTF-8 locale we currently have:
iswspace(0xA0)==1 and isspace(0xA0)==1
(because iswspace() and isspace() are the same code)
but must have
iswspace(0xA0)==1 and isspace(0xA0)==0
(because there is no such character and all others in the range
0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte
range because our internal wchar_t representation for UTF-8 is UCS-4).

Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may
return false positives (must be 0).
(because iswalpha() and isalpha() are the same code)

This change address this issue separating single byte and wide ctype
and also fix iswascii() (currently iswascii() is broken for
arguments > 0xFF).
This change is 100% binary compatible with old binaries.

1db8ba2474 - take out a needless panic under invariants for sctp_output.c
- Fix addrs's error checking of sctp_sendx(3) when addrcnt is less than
   SCTP_SMALL_IOVEC_SIZE
 - re-add back inpcb_bind local address check bypass capability
 - Fix it so sctp_opt_info is independant of assoc_id postion.
 - Fix cookie life set to use MSEC_TO_TICKS() macro.
 - asconf changes
   o More comment changes/clarifications related to the old local address
    "not" list which is now an explicit restricted list.

   o Rename some functions for clarity:
     - sctp_add/del_local_addr_assoc to xxx_local_addr_restricted()
     - asconf related iterator functions to sctp_asconf_iterator_xxx()

   o Fix bug when the same address is deleted and added (and removed from
     the asconf queue) where the ifa is "freed" twice refcount wise,
     possibly freeing it completely.

   o Fix bug in output where the first ASCONF would not go out after the
     last address is changed (e.g. only goes out when retransmitted).

   o Fix bug where multiple ASCONFs can be bundled in the same packet with
     the and with the same serial numbers.

   o Fix asconf stcb iterator to not send ASCONF until after all work
     queue entries have been processed.

   o Change behavior so that when the last address is deleted (auto asconf
     on a bound all endpoint) no action is taken until an address is
     added; at that time, an ASCONF add+delete is sent (if the assoc
     is still up).

   o Fix local address counting so that address scoping is taken into
     account.

   o #ifdef SCTP_TIMER_BASED_ASCONF the old timer triggered sending
     of ASCONF (after an RTO).  The default now is to send
     ASCONF immediately (except for the case of changing/deleting the
     last usable address).

8db32e8a1e Added environ-replacement detection. For programs that "clean" (i.e., su)
or replace (i.e., zdump) the environment after a call to setenv(), putenv()
or unsetenv() has been made, a few changes were made.
  - getenv() will return the value from the new environ array.
  - setenv() was split into two functions:  __setenv() which is most of the
    previous setenv() without checks on the name and setenv() which
    contains the checks before calling __setenv().
  - setenv(), putenv() and unsetenv() will unset all previous values and
    call __setenv() on all entries in the new environ array which in turn
    adds them to the end of the envVars array.  Calling __setenv() instead
    of setenv() is done to avoid the temporary replacement of the '=' in a
    string with a NUL byte.  Some strings may be read-only data.

Added more regression checks for clearing the environment array.

Replaced gettimeofday() with getrusage() in timing regression check for
better accuracy.

Fixed an off-by-one bug in __remove_putenv() in the use of memmove().  This
went unnoticed due to the allocation of double the number of environ
entries when building envVars.

Fixed a few spelling mistakes in the comments.

1e9af2c480 - Modular congestion control, with RFC2581 being the default.
- CMT_PF states added (w/sysctl to turn the PF version on)
- sctp_input.c had a missing incr of cookie case when the
  auth was bad. This meant a free was called without an
  increment to refcnt, added increment like rest of code.
- There was a case, unlikely, when the scope of the destination
  changed (this is a TSNH case). In that case, it would not free
  the alloc'ed asoc (in sctp_input.c).
- When listed addresses found a colliding cookie/Init, then
  the collided upon tcb was not unlocked in sctp_pcb.c
- Add error checking on arguments of sctp_sendx(3) to prevent it from
  referencing a NULL pointer.
- Fix an error return of sctp_sendx(3), it was returing
  ENOMEM not -1.
- Get assoc id was changed to use the sanctified socket api
  method for getting a assoc id (PEER_ADDR_INFO instead of
  PEER_ADDR_PARAMS).
- Fix it so a peeled off socket will get a proper error return
  if it trys to send to a different address then it is connected to.
- Fix so that select_a_stream can avoid an endless loop that
  could hang a caller.
- time_entered (state set time) was not being set in all cases
  to the time we went established.

1c8d4bbe18 Change the C wrappers for mmap/lseek/pread/pwrite/truncate/ftruncate to
call the pad-less versions of the corresponding syscalls if the running
kernel supports it.  Check kern.osreldate once per program and cache the
result to select the appropriate syscall.  This maintains userland
compatability with kernel.old's from quite a while back.

6f011a9012 Classify mmap, lseek, pread, pwrite, truncate, ftruncate as pseudo
syscalls, unless WITHOUT_SYSCALL_COMPAT is defined.  The default case
will have the .c wrappers still.  If you define WITHOUT_SYSCALL_COMPAT,
the .c wrappers will go away and libc will make direct syscalls.

After 7-stable starts, the direct syscall method will be default.

1b55a32fbf Adjust the syscall stub macros to be consistent in their meaning. In
particular:
SYSCALL() makes a syscall, with errno handling, and continues execution
directly after the macro in the non-error case.
RSYSCALL() is just like SYSCALL(), but returns after success.
Both SYSCALL(name) and RSYSCALL(name) export  "__sys_name" as a strong
symbol, with "_name" and "name" as weak aliases.
PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias.  It
still does "__sys_name" and "_name".

Change i386 to add errno handling to PSEUDO.  The same for amd64 and
sparc64, with appear to have copied the behavior.
ia64 was correct (as was alpha).  Just remove some apparently unused
variants of the macros. (untested!)
I believe powerpc is correct.
Fix arm to not export "name" from the PSEUDO case.  Remove apparently
extra unused variants.  (untested!)

The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO"
classified syscalls return without setting errno.  eg: "addr = mmap()"
could return with "addr" = 22 instead of setting errno to 22 and
returning -1.

196b6346ba Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.
