a5ad6b16c5 configure.ac: autodetect 'pause' instruction presence on sparc 
The change fixes the following build failure on sparc T3 and older CPUs:

```
sparc-unknown-linux-gnu-gcc ... -O2 -mcpu=niagara2 ... -c rwlock.c
{standard input}: Assembler messages:
{standard input}:398: Error: Architecture mismatch on "pause ".
{standard input}:398: (Requires v9e|v9v|v9m|m8; requested architecture is v9b.)
make[1]: *** [Makefile:280: rwlock.o] Error 1
```

`pause` insutruction exists only on `-mcpu=niagara4` (`T4`) and upper.

The change adds `pause` configure-time autodetection and uses it if available.
config.h.in got new `HAVE_SPARC_PAUSE` knob. Fallback is a fall-through no-op.

Build-tested on:

- sparc-unknown-linux-gnu-gcc (no `pause`, build succeeds)
- sparc-unknown-linux-gnu-gcc -mcpu=niagara4 (`pause`, build succeeds)

49462cf974 Make isc_rwlock.c thread-safe 
The ThreadSanitizer found several possible data races in our rwlock
implementation.  This commit changes all the unprotected variables to atomic and
also changes the explicit memory ordering (atomic_<foo>_explicit(..., <order>)
functions to use our convenience macros (atomic_<foo>_<order>).

62ca7743ae Fix compilation on CentOS 6 (i386) 
The stock toolchain available on CentOS 6 for i386 is unable to use the
_mm_pause() intrinsic.  Fix by using "rep; nop" assembly instructions on
that platform instead.
