814260f0b6 ppcmmu: Reduce unmapped physical memory logging. 
Don't log consecutive accesses to unmapped physical memory addresses. This saves a couple hundred thousand lines in the log in some cases.
This is only a partial fix. Any access that isn't logged should be queued and output if a log message is output that is not this log message or after a time period.

439509b408 Fix New World NVRAM limits calculations. 
It was possible to corrupt New World nvram using dingusppc setenv command.

- setenv must call get_config_vars to set data_length so that it can calculate free space.
- data_length represents the number of bytes taken by nvram variables including the terminating null for the value (name, '=', value, '\0'). Previously, it did not include the terminating null.
- The list of variables and values ends at a '\0' or at pos == 4096 bytes. Previously, data_length wouldn't get set if pos >= 4096.
- Allow setenv to create new nvram variables.
- Since data_length now represents the total number of used bytes, free_space now represents the actual free space, so use > free_space (instead of >= free_space) to determine insufficient space.
- While parsing nvram variable name, do not read beyond 4096 bytes.
- Use a different error message for each problem that can occur while parsing nvram variable name.

0c9ddaccf7 Fix dppc debugger printenv of multiline variables. 
If a nvram variable has CRLF or CR, replace them with LF so each line appears on a new line in the console output.
Also, add indent to each line so that each line appears only in the value column and not in the name column.
