we are processing has a base address of zero. Note that this will only
change behavior for devices where all the BARs of a given type have a base
address of 0 since we will enable the appropriate access when we encounter
the first BAR with a base that is not 0. Specifically, this allows certain
Toshiba laptops to no longer require 'hw.pci.enable_io_modes=0' to avoid
hangs during boot.

file's access time should be updated when it gets executed. A while
ago the mechanism used to exec was changed to use a more mmap based
mechanism and this behavior was broken as a side-effect of that.
A new vnode flag is added that gets set when the file gets executed,
and the VOP_SETATTR() vnode operation gets called. The underlying
filesystem is expected to handle it based on its own semantics, some
filesystems don't support access time at all. Those that do should
handle it in a way that does not block, does not generate I/O if possible,
etc. In particular vn_start_write() has not been called. The UFS code
handles it the same way as it would normally handle the access time if
a file was read - the IN_ACCESS flag gets set in the inode but no other
action happens at this point. The actual time update will happen later
during a sync (which handles all the necessary locking).

so that make(1) will run in an almost clean environment and enhance the
description of the test infrastructure.
Add the ability to have multiple tests carried out per test script.
Give some tests more meaningful names.
Fix the usage message from the test scripts.
Make it possible to pass several commands to the test scripts like:
'sh test.t setup run compare clean'.
to `:', so that it stays compatible with a stale dependency recorded in
.depend when the type of "foo" changes from file to directory or back.
Compensate for the loss of the "If no sources are specified, the target
is always re-created" feature by marking these targets with the .PHONY
attribute. While here, fix a bug in the target's script (nobody uses
these targets apparently).

NB: In FreeBSD 4.x and earlier, a script (file) named /etc/security
exists. Does mergemaster need to be taught how to replace a file with
a directory?

audit event identifier associated with each system call, which will
be stored by makesyscalls.sh in the sy_auevent field of struct sysent.
For now, default the audit identifier on all system calls to AUE_NULL,
but in the near future, other BSM event identifiers will be used. The
mapping of system calls to event identifiers is many:one due to
multiple system calls that map to the same end functionality across
compatibility wrappers, ABI wrappers, etc.

are subtle differences in the read and write completion path. Instead,
grab an extra write ref so the write path can drop it when we recursively
call bufdone(). I believe this may be the source of the wrong bufobj
panics.
