Nia Waldvogel 5e719b0d3d sync: fix concurrent read-lock on write-locked RWMutex
This bug can be triggered by the following series of events:
A acquires a write lock
B starts waiting for a read lock
C starts waiting for a read lock
A releases the write lock

After this, both B and C are supposed to be resumed as a read-lock is available.
However, with the previous implementation, only C would be resumed immediately.
Other goroutines could immediately acquire the read lock, but B would not be resumed until C released the read lock.

Ayke van Laethem c237633d34 all: use a custom sync package
The sync package is strongly tied to the runtime, so it's easier to
implement a new one. Besides, it's pretty big so it's better to replace
it.
