We have several callers that were formatting the argument strings themselves; consolidate this effort by adding new convenience functions directly in libqtest, and update some call-sites that can benefit from it. Note that the new functions qtest_startf() and qtest_vstartf() behave more like qtest_init() (the caller must assign global_qtest after the fact, rather than getting it implicitly set). This helps us prepare for future patches that get rid of the global variable, by explicitly highlighting which tests still depend on it now.

* This test is used to check that some Open Firmware based machines (i.e.
|
|
* OpenBIOS or SLOF) can be started successfully in TCG mode. To do this, we
|
|
* first put some Forth code into the "boot-command" Open Firmware environment
|
|
* variable. This Forth code writes a well-known magic value to a known location
|
|
* in memory. Then we start the guest so that the firmware can boot and finally
|
|
* run the Forth code.
|
|
* The testing code here then can finally check whether the value has been
|
|
* successfully written into the guest memory.
