Some subsystems will need to know for sure whether the switcher is
enabled or disabled during certain critical regions.
This patch provides a simple mutex-based mechanism to discover
whether the switcher is enabled and temporarily lock out further
enable/disable:
* bL_switcher_get_enabled() returns true iff the switcher is
enabled and temporarily inhibits enable/disable.
* bL_switcher_put_enabled() permits enable/disable of the switcher
again after a previous call to bL_switcher_get_enabled().
