Import Solaris support (#741)

This commit adds support for Solaris, squashed from PR #741:

Summary of additions:

* Initial setup of Solaris platform directory
* Add Solaris platform into autoconf template
* Uptime and load averages
* Add dependency on libkstat
* Basic process listing
* Zone name display
* CPU detection
* Per-process memory and CPU usage parsed correctly
* Uses sysconf to discover number of CPUs, instead of more complex libkstat code
* Simple memory display working
* Reduce repetitive calls to the PAGE_SIZE macro when reading memory info
* Add Project, Contract, Task, and Pool into process properties
* Use system major()/minor() implementations and remove extraneous definition of mkdev()
* Get the STARTTIME column working properly, using the Linux implementation as a guide
