- Log -----------------------------------------------------------------
Upstream version 0.50

Dana Jacobsen (42):
      Switch mpf_log to use Newton/Halley instead of AGM
      Don't get in log<->exp calling cycle
      Euler constant and li functions
      Ramp up precision in log for big speedup
      Fix rounding in str_real.  Add logreal and expreal functions internally.
      Add Euler, logreal, expreal, lir
      Change lir to li
      Add test for Euler constant
      Fix log for extremely small inputs where native log returns -inf
      Add tests for li
      Add powreal
      Split out mpf pi from string version
      Add ei for exponential integral
      POD fix
      Add mpf_agm, new log2 algorithm, log using AGM
      Comments
      Add agmreal, slight mod to Pi
      Update changes and todo
      Better rounding for li,ei.  Slightly better negative zeta behavior.
      Add tinyqs
      Split FP functions out of gmp_main.c into real.c.
      Move functions around in real.c -- all string funcs at the bottom
      New AGM log code, small speedups to exp/log/etc.
      Move log(2) to a const function like const_pi and const_euler
      AGM log was using far too much precision.  AGM is always faster than Newton/Halley on exp, so just always use it.
      Cache Pi,Euler,Log2 constants
      Rewrite mpf_exp
      Remove lots of trailing spaces from tinyqs.c
      Faster Pi (Ramanujan/Chudnovsky)
      Small optimization to Pi
      Update Ramanujan Pi.  Calling Pi/Euler in void context doesn't stringify.  Add _GMP_memfree() function.
      Add missing mpz_clear in ramanujan_pi
      Comment changes
      Consistent ladder for exp lifting
      mpf li and ei can be called internally
      Add prime_count_lower and prime_count_upper
      Bump version number
      Rounding error in Pi const
      More rounding
      Date on Changes
      Compiler warnings and a type mismatch
      Bump version
