Sort functions in verify_packages.c

There are four independent activities performed in verify_packages: obtaining
and caching list of installed packages, deciding what operations need to be
performed on packages, performing operations and cleanup.

The activities share data over global variables (PACKAGE_SCHEDULE,
INSTALLED_PACKAGE_LISTS), so it is not yet possible to split this module into
four independent ones, but at least sorting those into groups helps to
understand the structure of the code.

Implement $(sys.cpus) on HP-UX platform

Uses the HP-UX mpctl() function to query the number of processors
available system-wide (as opposed to within a processor set) in order
to populate the $(sys.cpus) variable.

In HP-UX running on Intel Itanium Hyper-Thread Technology processors,
where each CPU core has two virtual cores, the total number of virtual
- rather than physical - cores is provided, which corresponds to the
behavior of the Linux scan of the /proc/stat file with HTT is enabled
on x86 platforms.

On a PA-RISC system, the total number of physical cores is set. The
PA-8900 processor has two physical cores per CPU socket, so an rp8420
with 16 PA-8900 processors will set $(sys.cpus) to 32, as expected.

It may be worthwhile to implement a $(sys.cpusockets) variable too,
in light of things like Oracle and Red Hat licensing.

The mpctl() function is documented at this page:

Replace date +%s in testall with more widely compatible code (Mantis #1254)

In order to calculate the total run time of acceptance tests, the
testall script needs the UNIX seconds - a time() call - of the start
and end times of the test runs. It currently uses the command
"date +%s" to get these times.

Many older OS platforms - such as HP-UX 11.11, Solaris 8 and 9, and
others - do not support the "%s" format for the date command.

This patch creates a unix_seconds() subroutine which uses the modern
"date +%s" command if available, falls back to a Perl "print time()"
call, and failing that it falls back to pulling the octal date out of
a pax-created cpio header for an empty temporary file and converting
it to decimal using "bc."

This code will work on every POSIX-compliant platform (since the
pax/cpio/bc approach is strictly POSIX) as well as any platorm that
has a copy of Perl in the path.
