Ian Lance Taylor 87ad863f35 runtime: use atomic ops for fwdSig, make sigtable immutable
The fwdSig array is accessed by the signal handler, which may run in
parallel with other threads manipulating it via the os/signal package.
Use atomic accesses to ensure that there are no problems.

Move the _SigHandling flag out of the sigtable array. This makes sigtable
immutable and safe to read from the signal handler.
