Yukihiro "Matz" Matsumoto a7462a7f42 Remove redundant flo_hash function.
`flo_hash` implemented `15.2.8.3.18` but `Kernel#hash` (15.3.1.3.15)
now works for numbers.

Yukihiro "Matz" Matsumoto 83fc915213 Add new range check macro FIXABLE_FLOAT(); ref #3652

which only has 53 bits significant precision.

Franck Verrot 2588507285 Remove unnecessary backticks.
Dr Markus Kuhn published in 1999 an article [1] explaining in details
why we shouldn't use the ASCII grave accent (0x60) as a left quotation.

Backticks have been used most notably to produce nice-looking LaTeX
documents but it doesn't seem to be an issue on modern platforms and
for the oldest ones, there are workarounds as mentioned by Dr Kuhn.

cremno 6f893b5183 re-implement mrb_float_to_str()
The new implementation is backwards incompatible, but I couldn't find
any usage outside mruby and I also couldn't think of a different and
good name.

All ISO C99 printf conversion specifiers for floating point numbers and
an optional precision are supported.

It is largely based on code from the MIT licensed musl libc
(http://www.musl-libc.org/) and its floating point printing is exact
(unlike the current code behind Float#to_s).
