illumos gate

FYI; with the two earlier changes now integrated, this one remains. I've run `wsdiff` against these and only observed noise:

: doctor; wsdiff -vu -r wsdiff.out proto.control proto

Digging into the output file, one sees three classes of change:

1. git hashes and branch names embedded various places,
2. new typedef's added to header files (and whitespace changes),
3. __LINE__ changes due to line numbers shifting slightly

Otherwise, the builds seem to be identical. Recall, also, that this change was tested when the prior two changes in the series were tested.

Using standard diff output instead of unified diff output, I can filter out a lot of the __LINE__ noise:

: doctor; egrep -v '^([0-9]+(,[0-9]+)?c[0-9]+(,[0-9]+)?|---)$' wsdiff.out2 | egrep -v ' (mov[lq]|pushl) '

All of this output is expected. Note that those hex bytes in the stanza for iasl are part of long instructions that, in the disassembly output, spill onto a new line.
