Introduce CLAMP macro. Unify all MIN(MAX(a,b),c) uses. With the CLAMP macro replacing the combination of MIN and MAX, we will have at least two advantages: 1. It's more obvious semantically. 2. There are no more mixes of confusing uses like MIN(MAX(a,b),c) and MAX(MIN(a,b),c) and MIN(a,MAX(b,c)) appearing everywhere. We unify the 'clamping' with a single macro. Note that the behavior of this CLAMP macro is different from the combination `MAX(low,MIN(x,high))`. * This CLAMP macro expands to two comparisons instead of three from MAX and MIN combination. In theory, this makes the code slightly smaller, in case that (low) or (high) or both are computed at runtime, so that compilers cannot optimize them. (The third comparison will matter if (low)>(high); see below.) * CLAMP has a side effect, that if (low)>(high) it will produce weird results. Unlike MIN & MAX which will force either (low) or (high) to win. No assertion of ((low)<=(high)) is done in this macro, for now. This CLAMP macro is implemented like described in glib <http://developer.gnome.org/glib/stable/glib-Standard-Macros.html> and does not handle weird uses like CLAMP(a++, low++, high--) .

Mark signal tables 'const' Specifically, Platform_signals[] and Platform_numberOfSignals. Both are not supposed to be mutable. Marking them 'const' puts them into rodata sections in binary. And for Platform_numberOfSignals, this aids optimization (aids only Link Time Optimization for now). :) Signed-off-by: Kang-Che Sung <explorer09@gmail.com>

Support ZFS ARC stats on FreeBSD New meter displays same ARC stats as FreeBSD top(1). Can be extended to other platforms that support ZFS. Pulling kstat.zfs.misc.arcstats.c_max as the meter total, so the meter has a meaningful value to work up to. The Text meter displays, first, the maximum ARC size (Meter.total), then second, the total ARC used, using the difference between Meter.maxItems and Meter.curItems to "hide" the used value from the Bar and Graph drawing functions by using an index in Meter.values[] that is beyond curItems - 1, but less than maxItems - 1.
