Luigi Rizzo 4f1e3c3c4c Fix a couple of problems which could cause panics at runtime:
+ setting a bandwidth too large for a pipe (above 2Gbit/s) could
   cause the internal representation (which is int) to wrap to a
   negative number, causing an infinite loop in the kernel;

 + (see PR bin/35628): when configuring RED parameters for a queue,
   the values are not passed to the kernel resulting in panics at
   runtime (part of the problem here is also that the kernel does
   not check for valid parameters being passed, but this will be
   fixed in a separate commit).

These are both critical fixes which need to be merged into 4.6-RELEASE.

Maxim Sobolev a1ad4f468a New feature: allow origins of all dependencies be recorded into package list
using new `@comment DEPORIGIN:...' directive. This would allow us to make
many neat things including:

- easier binary upgrades;
- source upgrades without using external tools by simply extending
  bsd.port.mk and pkg_install tools;
- mixed-mode upgrades (source + binary);
- depreciate and deorbit silly +REQUIRED_BY files in the near future.

This feature is no-op until appropriate bsd.port.mk patch is committed, and
even when it is already committed packages generated will remain 100%
compatible with old set of pkg_install tools (module all those neat
features, of course).

Maxim Sobolev f351f851db In a origin lookup mode (-O) don't bail out when encountering empty package
directory, because this prevent this option from being used from the
package-depends target of bsd.port.mk since it creates such empty dir
during its normal operation.

Juli Mallett 305e39f49b Modify the -p implementation to use a user's locale, so they can respond to
the prompt in their native language.

Also make the prompt fit what POSIX asks for (?...).

This should not affect use of -p with yes(1) [as every locale I know of matches
'y' as YESEXPR as well], but that's what -t is for anyway.  -p is meant to be
really used interactively.

Juli Mallett 634d96e194 Check for possible overflow from sysconf _SC_ARG_MAX and error out in a
correct manner.  Revert my incorrect change to use err(3) for malloc(3)
failing.  Use a size_t variable to store the size of the argument buffer
we allocate, and remove silly casts as the result of having this around.
Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer.  Remove the static qualifier for arg_max, and the bogus setting
of it to -1.

Include <limits.h> for the definitions we use to check for possible
overflows.

Juli Mallett 9104507502 In an effort to make this utility easier to work with at a source level, move
out the parse loop to a seperate function, and move local variables around as
is needed.  To keep the state of some variables and keep from having huge arg
lists to functions, make a bunch global.

Change use of err(3) in situations where malloc(3) will be setting errno to
errx(3) since assuming malloc(3) sets errno is non-portable, and provides no
more useful information in the context of FreeBSD.

Crist J. Clark f5a8f1482c Remove leading whitespace from the setuid file lists.
Due to the way we run ls(1), through xargs(1), the leading whitespace
can change even when the setuid files haven't. To avoid displaying
these lines, we currently run diff(1) with the '-w' option. However,
this is probably not the ideal way to go; there is a very, very small
possibility for diff(1) to miss things is shouldn't. So, with the
leading space cleaned, we can revert to the '-b' option which is
"safer."
