198ee3001d Move snmp_hast manual to section 3, where all other manual pages for 
bsnmp modules are located.

Section 3 (Library Functions) looks wrong for this manual page, which
contains only module description, that is why initially it was located
to section 8 (System Manager's Manual).  On the other hand manual
pages for all other bsnmpd modules are already located in the section
3, and having all pages in one section looks more consistent.  Also,
currently, similarly to manuals for other modules, snmp_hast manual
contains LIBRARY section, which is not good style for section 8.

7e659f9491 Add the Clang specific -Wmissing-variable-declarations to WARNS=6. 
This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.

Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

aebd8de674 hrStorageSize and hrStorageUsed are 32 bit integers, reporting a fs 
size and usage in hrStorageAllocationUnits. If the file system has
more than 2^31 allocations it can not be shown correctly and the
meters are useless.

In such cases follow net-snmp behaviour and increase
hrStorageAllocationUnits so the values fit under INT_MAX.

16c3b091ae In snmp_hostres, device_map table is used for consistent device table 
indexing. When a device has gone it is not removed from device_map
table but just its entry_p field is set to NULL.

So when traversing device_map in disk_OS_get_ATA_disks() and
disk_OS_get_MD_disks() check for entry_p being NULL, otherwise the
bsnmpd crash is possible when a removed map entry is dereferenced.

Before the fix, for disk_OS_get_ATA_disks() the crash could be easily
reproduced running:

  atacontrol detach ata1

The crash was not observed in disk_OS_get_MD_disks() because currently
snmp_hostres does no see md(4) disks: to get the device list it uses
devinfo(3), which does not return md devices.

d6d3f01e0a Merge the projects/pf/head branch, that was worked on for last six months, 
into head. The most significant achievements in the new code:

 o Fine grained locking, thus much better performance.
 o Fixes to many problems in pf, that were specific to FreeBSD port.

New code doesn't have that many ifdefs and much less OpenBSDisms, thus
is more attractive to our developers.

  Those interested in details, can browse through SVN log of the
projects/pf/head branch. And for reference, here is exact list of
revisions merged:

6b99842ada Globally replace u_int*_t from (non-contributed) man pages. 
The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

It's too late to change this in 9.0 -- so we have a release with the

8f64015c0e Use full buffer size in read(2) call, there is no need to preserve the 
last byte of the buffer.

Since we call refresh_device_tbl() for any devctl event types - no need
to check the first byte of buffer. Remove these checks.

Also remove logging for the case of unknown devd message. It incorrectly
triggers when all devctl events are not fit into one buffer and part of
unread data will be read in the next pass.

When length of data readed from devctl is equal to sizeof(buf), then try
to read from socket again, to read full data.

ac203a768d Fix CPU load reporting independent of scheduler used. 
- Sample CPU usage data from kern.cp_times, this makes for a far more
  accurate and scheduler independent algorithm.
- Rip out the process list scraping that is no longer required.
- Don't update CPU usage sampling on every request, but every 15s
  instead. This makes it impossible for an attacker to hide the CPU load
  by triggering 4 samplings in short succession when the system is idle.
- After reaching the steady-state, the system will always report the
  average CPU load of the last 60 sampled seconds.
- Untangling of call graph.
