debug: Remove catchsegv and libSegfault (BZ #14913)
Trapping SIGSEGV within the process is error-prone, adds security issues, and modern analysis design tends to happen out of the process (either by attaching a debugger or by post-mortem analysis). The libSegfault also has some design problems, it uses non async-signal-safe function (backtrace) on signal handler. There are multiple alternatives if users do want to use similar functionality, such as sigsegv gnulib module or libsegfault.

'Trap' is the address of the exception:

00200 - Machine check exception (memory parity error, for instance)
|

00300 - Data access exception (memory not mapped, see dsisr for why)
|

00400 - Instruction access exception (memory not mapped)
|

00500 - External interrupt
|

00600 - Alignment exception (see dsisr for more information)
|

00700 - Program exception (illegal/trap instruction, FP exception)
|
||||
00800 - FP unavailable (should not be seen by user code)
|

00900 - Decrementer exception (for instance, SIGALRM)
|

00A00 - I/O controller interface exception

5 - trying to access I/O controller space or using lwarx/stwcx on

10 - segment table search failed to find translation (64-bit ppcs only)
