prevent using mahaf if it's going to fail anyway
module_init: add ModuleIsError (allows acpi and mahaf init routines to
pass failure notification on to their second and later callers)
counter: safer memory management
This was SVN commit r5333.
. update moduleInit mechanism and move it out of lib.cpp. now has a
thread-safe reference count and allows repeated init/shutdown (required
for self-tests)
. vfs now depends on h_mgr; h_mgr need therefore no longer explicitly be
shutdown (e.g. in self-tests)
. acpi: minor fixes
. cpu: AtomicAdd and CAS now take volatile variable (safer)
. mahaf: unload driver on shutdown (did this for DriverVerifier, but
it's 'cleaner' in general)
. wdbg_sym
. wfilesystem: get rid of manual declarations of deprecated functions;
implement them via trampoline instead
This was SVN commit r5086.
