GXemul Code2

The mechanism for detecting when to assert MIPS compare interrupts could sometimes stop delivering interrupts, if the count register was read. Fixed by keeping track of how many times the register is read and reverting it before doing the count/compare interrupt assert check. (Thanks to Jakub Jermar for noticing this bug using HelenOS.)

Beginning on CacheComponent (a generic memory cache component). (Does nothing, so far.)

Include HTML link to machine templates (not just other components), from generated trees.

Man page reflects September 2010.

Improved the "pretty print" of components in the tree dump, by moving it out to a per-component virtual function.

Overwrite memory with nonsense on free().

Updating the OpenBSD/landisk guest operating system install instructions from 4.6 to 4.7.

HISTORY comment for r5734.

Adding a hack for outputting raw .ppm dumps of framebuffer contents. Useful for e.g. making movies of GXemul runs.

nbjoerg on #GXemul (FreeNode) noticed an easy way to trigger an unhandled case in memory_sh.cc. Hopefully this is the correct solution.
