MFC r340361:

Fix printing of 64-bit counters on 32-bit ppc platforms.

Several statistic counters are uint64_t values and are printed by systat
using %lu. This results in displaying wrong numbers. Use PRIu64 instead.
While there, print variables of size_t using %zd.

systat: use and correctly display 64bit counters.

Following struct vmtotal changes, make systat use and correctly
display 64-bit counters. Switch to humanize_number(3) to overcome
homegrown arithmetics limits in pretty printing large numbers. Use
1024 as a divisor for memory fields to make it consistent with other
tools and users expectations.

Patch systat -zarc to display cumulative rate and round down large numbers by SI units

Introduce sysputpage() to display large page size with human readable format.

Using UI units allows to fit larger numbers in columns.
Stop calling v_page_size - this is a value that doesn't change at runtime.
Renamed WINDOW *wnd to *wd to avoid conflict with global *wnd variable.
Use bit-shift to convert page size to byte.
