estd: switch to https

Log message:
add support for SIGUSR1/SIGUSR2 to adjust frequency instead of strategy.
new -x means USR1 reduces the minimum and USR2 increases the minimum,
and new -X adjusts the maximum similarly.
-X is designed to allow the user to force the CPU into a lower speed
frequency, without having to restart estd entirely.  -x was added for
symmetry.

Log message:
various fixes for arm64 big endian support.
most of these simply extend matching from "aarch64" to \ 
"aarch64eb"
in various forms of code.  most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.
no pkg-bump because this shouldn't change packages on systems that
could already build all of these.
