ISC_PLATFORM_USEBACKTRACE

[Gary E. Miller]

Yo Hal!

By jamming a number of #defines the hard way, I get libisc backtrace
to do what it is supposed to do:

../../ntpd/ntpd.c:930: REQUIRE(1 == 2) failed, back trace
#0 0x556b8bf1d76f in ??
#1 0x556b8bf1d65a in ??
#2 0x556b8beecf8f in ??
#3 0x556b8beed060 in ??
#4 0x7f81ca395720 in ??
#5 0x556b8bed9299 in ??
05-30T20:05:32 ntpd[9143]: SIGSYS: got a trap. Probably seccomp omission. Bailing.

There was never a way to decode the addresses beyond that.  Is
that any use?  Any way to improve it so it has value?

This part prolly needs improvement, in this case a failed assert():

"SIGSYS: got a trap. Probably seccomp omission. Bailing."
