clock time to uptime because wall clock time may go backwards.
This is a change in the API which will impact SNMP agents who are using
ifi_epoch to set RFC2233's ifCounterDiscontinuityTime. None are know to
exist today. This will not impact applications that are using the
<index, epoch> tuple to verify interface uniqueness except that it
eliminates a race which could lead to a false assumption of uniqueness.
Because this is a behavior change, bump __FreeBSD_version.

o change the mapping arrays to have a zero offset rather than base 1;
this eliminates lots of signo adjustments and brings the code
back inline with the original netbsd code
o purge use of SVR4_SIGTBLZ; SVR4_NSIG is the only definition for
how big a mapping array is
o change the mapping loops to explicitly ignore signal 0
o purge some bogus code from bsd_to_svr4_sigset
o adjust svr4_sysentvec to deal with the mapping table change

owned by a process when it forks, and creates a matching set of references
for the child process, as prescribed by POSIX.
In order to avoid races with other threads in the parent process during
fork(), it is necessary to allocate a temporary reference list while
holding the sem_lock, then transfer those references to the new process
once the sem_lock is released. The implementation is inefficient but
appears functional; in order to improve the efficiency, it will be
necessary to modify the existing structures and logic, which generally
rely on O(n) operations over the global set of semaphores.
PAGE_SIZE.
Unlike originator of the PR suggests retain MAXSHELLCMDLEN definition
(he has been proposing to replace it with PAGE_SIZE everywhere), not only
this reduced the diff significantly, but prevents code obfuscation and also
allows to increase/decrease this parameter easily if needed.

o Use VOP_GETATTR() to obtain actual size of file and parse no more than that.
Previously, we parsed MAXSHELLCMDLEN characters regardless of the actual file
size. This makes the following working:
$ printf '#!/bin/echo' > /tmp/test.sh
$ chmod 755 /tmp/test.sh
$ /tmp/test.sh
Previously, attempts to execve() that shell script has been failing with bogus
ENAMETOOLONG.

- Simplify CARP_LOG() and making it working (we don't have addlog in FreeBSD).
- Introduce CARP_DEBUG() which logs with LOG_DEBUG severity when
net.inet.carp.log > 1
- Use CARP_DEBUG to log state changes of carp interfaces.
After CARP_LOG() cleanup it appeared that carp_input_c() does not need sc
argument. Remove it.

script with first line not ending in '\n'.
Also, treat '\0' as line terminating character, which may me useful in
some situations.

- implement set_border to scrub X remnants when switching back to VTYs
- implement mmap, only allowing addresses within the range of the
console adapter.
