No longer abuse the desk field, instead making use of the path. Reject
any scries outside of the local ship, empty desk and current time as
invalid.
Expose ducts only under a debug endpoint, nothing else should care about
being able to inspect them.
Add scry endpoints for the very next timer (if any), and all timers up
to and including a specified timestamp.

This patches libsigsegv to not check the stack vma on Linux, since that
involves reading procfs, and we make very heavy use of sigsegv. This
eliminates most of urbit's performance discrepancy between Linux and
MacOS. These are the benchmarks used; note this is a local MBP vs a
cloud Linux server, and the MBP is almost certainly faster hardware.
We take two benchmarks, one of which decrements 10 million times and the
other simply allocates 125MB of memory. These are the results:
cpu-heavy == =/ n 10.000.000 |-(?~(n n $(n (dec n))))
mem-heavy == =a (bex 1.000.000.008)
macos, cpu-heavy: 6 seconds
macos, mem-heavy: 1 second
linux-before, cpu-heavy: 30 seconds
linux-before, mem-heavy: 160 seconds
linux-after, cpu-heavy 9 seconds
linux-after, mem-heavy 1.3 seconds
This represents a 3x speedup for the cpu-heavy operation and a 120x
speedup for the memory-heavy operation.
This check was used to try to distinguish stack overflow from other
forms of segmentation fault. In the comments in src/handler-unix.c, it
describes three heuristics it uses, depending on what's available from
the OS. In the linux-i386 case, all three are availble, so we simply
disable the slow one. This correctly recognizes stack overflow if you
simply alloca(10000000000).
