This also includes a bunch of my pending work including
- Updated serial code so we can compile in different serial port speeds
- Updates to the build system so that:
- Makefile.settings holds all of the settings of the config variables
- ldoptions and cpuflags are generated automatically with perl scripts
- src/config/Config holds all of the architecture neutral make file settings
- Initial work on the P4 including how to use cache as ram
- Update to the ioapic code for the P4 because it delivers irqs on the system
bus instead of an out of band bus
- Updated version of printf that doesn't need an intermediate buffer
- logbuf_subr now handles the case when we want to use a log buffer
- video_subr handles the preliminary code for writing to a video device.
- Pending changes for the L440GX are merged in as well (hopefully I haven't
messed then up since they were written).
First, grow heap size in src/arch/i386/config/ldscript.base for DoC
Minor include fixes
Fixes to cua -- but it's now broken, won't find IDE
Minor fix to util/config/NLBConfig.py: for docipl, use CFLAGS
Added files so that CUA works with config tool.
