PR/56881: hppa: backtrace_symbols() delivers bogus results for some dynloaded functions

Install gcc's unwind.h instead of libexecinfo's

The prototypes in libexecinfo's unwind.h do not match those commonly
used (e.g. by gcc, clang, GNU libunwind, LLVM libunwind...), causing
C++ programs to fail to build on type mismatches (e.g. compiler-rt,
libc++abi). Rather than providing our own header, reuse the one
included in gcc.

use provide KERN_PROC_PATHNAME in PROC_ARGS.

From Ed Maste:

libexecinfo: Include terminating null in byte count

Otherwise, a formatted string with a strlen equal to the remaining
buffer space would have the last character omitted (because vsnprintf
always null-terminates), and later the assert in backtrace_symbols_fmt
would fail.

use sysctl to find the pathname argv[0] if available (from FreeBSD via

If Unwind_Backtrace is broken, ctx.n will still contain ~0, and we will
return that which poor behavior for the user, so return 0 instead.
We could document ~0 to be an error, but that would deviate from the
Linux behavior which is not desirable. Noted by Poul-Henning Kamp

Fix using gcc's unwind.h

make the backtrace()'s tracer() return _URC_FOREIGN_EXCEPTION_CAUGHT
when the array is full. it won't be able to do any more work if so,
and avoids infinite loops in unwinding as seen on arm64.

XXX: lack of signal support here means that backtrace() is useless
XXX: from a signal handler, such as attempting to display the stack
XXX: when handling a SIGSEGV.
