Rewrite OsdSynch.c to reflect the latest ACPICA more closely:

- Implement ACPI semaphore (ACPI_SEMAPHORE) with condvar(9) and mutex(9).
- Implement ACPI mutex (ACPI_MUTEX) with mutex(9).
- Implement ACPI lock (ACPI_SPINLOCK) with spin mutex(9).

Clean up FreeBSD-specific header file:

- Define ACPI_USE_DO_WHILE_0 to add do while(0) around return_*() macros.
- Define __cdecl only for user land. It will never be used in kernel.
- Remove __cli() and __sti(). They were deprecated long ago.
