Fixed constants pi and log(2) computation when logging is used: When
MPFR is built with logging support, these two constants are used by
the logging functions (via mpfr_fprintf, then mpfr_log, for the base
conversion). Since the mpfr_cache function isn't re-entrant when
working on the same cache, we need to define two caches for each
constant. Otherwise the constants could be incorrect; for instance,
"MPFR_LOG_ALL=1 ./tconst_pi" was failing.
Note: the bug was introduced with the new logging system from r7575
for MPFR 3.1.0, based on mpfr_fprintf instead of mpfr_out_str (which
doesn't depend on mpfr_log).
