Set sa_restart flag when calling sigaction().
...
This ensures that if a mutator thread is blocked in a system call when
the MPS handles a signal, the system call will not fail with EINTR but
instead will be restarted.
Add a test case for the thread suspend and resume signals.

Improve clarity of product configuration so that names more explicitly indicate what they do:
...
* CONFIG_POLL_NONE (because the user-visible consequence is that polling is no longer supported; was CONFIG_PROTECTION_NONE).
* DISABLE_LOCKS (was THREAD_SINGLE).
* DISABLE_SHIELD (was THREAD_SINGLE && PROTECTION_NONE)
* DISABLE_REMEMBERED_SET (was PROTECTION_NONE)
When the shield is disabled, ArenaLeave asserts that there are no busy traces, and ArenaPoll is a no-op.
By having functions implemented using the corresponding macro, we can avoid duplicated code, and avoid testing DISABLE_SHIELD in global.c.
Remove all remaining references to MPS_PROD_EPCORE.
