- define test environments (columns)
- define test cases (rows)
And final call of simplebench API.

This patch introduces two lock guard macros that automatically unlock a
lock object (QemuMutex and others):
void f(void) {
QEMU_LOCK_GUARD(&mutex);
if (!may_fail()) {
return; /* automatically unlocks mutex */
}
...
}
and:
WITH_QEMU_LOCK_GUARD(&mutex) {
if (!may_fail()) {
return; /* automatically unlocks mutex */
}
}
/* automatically unlocks mutex here */
...
Convert qemu-timer.c functions that benefit from these macros as an
example. Manual qemu_mutex_lock/unlock() callers are left unmodified in
cases where clarity would not improve by switching to the macros.
Many other QemuMutex users remain in the codebase that might benefit
from lock guards. Over time they can be converted, if that is
desirable.

This will be needed for lock guards, because if the lock is NULL the
dummy for loop of the lock guard never runs. This can cause confusion
and dummy warnings in the compiler, but even if it did not, aborting
with a NULL pointer dereference is a less surprising behavior.

The Linux kernel recently started using FAST_READ_4 commands.
This results in flash read failures. At the same time, the m25p80
emulation is seen to read 8 more bytes than expected. Adjusting the
expected number of dummy cycles to match FAST_READ fixes the problem.

Whenever an unsupported command is encountered, the current code
interprets each transferred byte as new command. Most of the time, those
'commands' are interpreted as new unknown commands. However, in rare
cases, it may be that for example address or length information
passed with the original command is by itself a valid command.
If that happens, the state machine may get completely confused and,
worst case, start writing data into the flash or even erase it.
To avoid the problem, transition into STATE_READING_DATA and keep
sending a value of 0 until the chip is deselected after encountering
an unsupported command.
