Fix parsing of hexadecimal floating-point numbers whose significand (aka "mantissa") values are too large to fit in UV range. Such literals (for example, 0x1234567890.1p+0 for 32-bit IV/UV platform, or 0x1234567890_1234567890.1p+0 for 64-bit IV/UV) used to be parsed incorrectly.
Perl 5.42.0 does not handle the transition to/from daylight savings time properly. The time and/or timezone can be off by an hour in the intervals surrounding such transitions. This is a regression from earlier releases, and is now fixed. This bug was evident from perl space in the "strftime" in POSIX function, and in XS code with any of "my_strftime" in perlapi, "sv_strftime_ints" in perlapi, or "sv_strftime_tm" in perlapi.

Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish.
