2401957e62 Extend forktest so that it does allocation before the fork and collection afterwards; this ensures that we hit the read barrier and thus exercise the exception handling. 
After forking in the child, re-create exception port and exception thread, and re-register the (only) thread with that port.

8c3e5886b4 Vmpagesize now takes no arguments -- this avoids suggesting (incorrectly) that it might return a different value for each vm. 
New function ProtGranularity returns the protection granularity of the operating system. (On all currently supported operating systems this is the same as the granularity of memory mapping returned by VMPageSuze, but it's important to separate these concepts.) MPMCheck asserts that the granularity of memory mapping is a multiple of the granularity of protection.
Client arena supports MPS_KEY_ARENA_GRAIN_SIZE.
Some of the test cases set the arena grain size.

fb2443daaa Fix the build for gcc on os x: gcc warns about the missing return in protcatchthread, but we don't want to add one because that would be unreachable code. so use __attribute__((__noreturn__)) instead.

643ab5a49a 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.

b471aeb616 Registering exception handler for each thread, rather than the whole task. 
This avoids the need to forward exception messages to the debugger, since we can reasonably insist that we're the first handler in the chain for each thread.
