PRIV_KMEM_READ is different from other PRIV_* checks in that it's allowed

Quoting illumos issue #3836:
Currently zio_free() always puts the zio on a list for subsequent
processing by zio_free_sync(). This is only necessary for frees that
might need to issue reads (gang and dedup blocks).
By processing the majority of the frees as we encounter them, we reduce
the amount of time that the spa_sync() thread spends burning CPU and
not doing any i/o, thus increasing the overall write throughput of the
system.

mktemp(), mkstemp() and mkdtemp() are available in standard <stdlib.h> and
also in <unistd.h>. Encourage use of the former by listing it in the
synopsis.
Gcc outputs pre-UAL asm and expects the ldcl instruction with a condition
in the form ldc<c>l, where the code produces the instruction in the UAL
form ldcl<c>. Work around this by checking if we are using clang or gcc and
adjusting the instruction.
While here correct the cmp instruction's value to include the # before the
immediate value.
(this is designed to allow new modules to be installed via ports/packages).
To prevent conflict with itself (sysutils/bsdconfig) as a port (which
installs its base modules to the above directory, it was long-ago decided
that so-called `base' modules would look different than now-defined `add-on'
modules. The structure of the contents for each is the same, but the naming
convention for the module directory must be different.
Base modules are named `[0-9][0-9][0-9].*' to allow SysV-style organization
while add-on modules must avoid this naming style and are simply listed in
alphabetical order by their module directory.
For example, a hypothetical port named `bsdconfig-jails' could install
/usr/local/libexec/bsdconfig/jails and provide `bsdconfig jails' as well as
a new menu entry in the main-menu.
Add-on modules are listed in the main-menu (when bsdconfig is executed with-
out arguments) below a separator after the last base-module.
In `bsdconfig -h' output, add-on modules are listed right alongside base
modules (sorted alphabetically in columnar fashion; left-to-right).
If a base module declares a keyword used by an add-on module, the base
module will always win when given `bsdconfig keyword' syntax.
Add-on modules should avoid declaring any keyword found in `script.subr' as
a reserved-word (`Resword') since bsdconfig also supports `bsdconfig resword'
as a fall-back if no keyword is found to be declared by any module.
Do not inherit $SYSRC_VERBOSE from operating environment. The concern is
that when a user (such as myself) which has SYSRC_VERBOSE=1 in his/her
~/.bash_profile or such that when they are told to execute a command like:
hostname `sysrc -n hostname`
NOTE: To activate a recently configured hostname.
If $SYSRC_VERBOSE is set, then POLA is violated because the output of sysrc
is indirectly influenced (making for an inconsistent experience).

difference between these two functions:
Usage: f_show_msg() $format_string [ $format_args ... ]
Usage: f_dialog_msgbox() $text [ $hline ]
The former lends itself well to displaying the $msg_* i18n text, prompts,
etc. While the latter is better for text you do not control (error strings
captured as a response from external commands) -- or if you have to control
the hline.
Both scripted access (packageDelete) and UI access have been tested
successfully with a variation of different situations including:
+ Uninstall a package which no other installed package depends
+ Uninstall multiple packages which no other installed packages depend
+ Uninstall multiple packages which depend on each other
+ Similar to above but when ordered removal requires tracing dependencies
+ Purposefully do things like uninstall a package that is not installed
+ Try to uninstall a package which other installed packages still depend
+ Try to uninstall multiple packages which other installed packages depend
+ And many more.
