Fix return value for bad pci config address
...
PCI config read fails should return all 1 bits.
All unused registers in an existing PCI device should return 0.
Because that's what my Power Mac 8600 returns when I run my Open Firmware lspci command.
Any bus/device/function that doesn't exist returns FF and won't be listed by lspci.
Any registers that are unused will show as 00 in the lspci output.
Make grackle log bus:device.function @register.size in all cases.

Add nvedit
...
setenv doesn't allow entering strings that include multiple lines which is useful for nvramrc.
nvedit uses CTRL-C to end editing, like Open Firmware. It does not support deleting characters from a line or editing previous lines or any other special keys. It doesn't have nvstore or nvquit or nvrecover commands. Basically, you should edit your nvramrc in a text editor, then copy and paste into the debugger.

Fix setenv and printenv
...
- Allow changing integer variables. Previously they could not be changed.
- Allow changing string variables. Previously they could only be changed if their length increased.
- printenv had a bug with strings longer than 32 characters.
- printenv now translates carriage return (used in nvramrc) as endl (which should perform carriage return and linefeed)
- For integers, setenv assumes decimal number input but if that fails it will try hex conversion. 0x prefix for hex numbers is optional unless the number only has digits 0 - 9.
- setenv converts linefeed to carriage return for string variables. nvramrc requires this for proper editing in Open Firmware.
- Added Open Firmware 2.4 nvram field names to OfNvramHdr comments.
