Here's a proposed renaming. Alternate proposals and discussion welcome

old name new name e stays the same log2_e log2E log10_e log10E ln_2 ln2 (or logE2 if we decide to use logE instead of ln in Math module - log function and log/ln param names are inconsistent · Issue #18995 · chapel-lang/chapel · GitHub) ln_10 ln10 (or logE10, ditto connection above) pi stays the same half_pi halfPi quarter_pi quarterPi
