Changes from the Plan 9 acid (beyond the
obvious changes necessary to compile without
Ken's compiler and with the new libmach interface).
========================================
the input-line print verb is %Z, so that %L can be for locations
the register block is explicitly "mapped" at 0 by xget1, xget2, ...
for compatibility with old acid, even though libmach
doesn't participate in this lie anymore.
main accepts pid, file, and core in any order
the ptab only records pids (no ctl fd anymore).
new builtin sysstop(pid) runs pid until the next syscall
map() returns 5-tuples: (name, filename, base, end, offset)
filename is new
map() expects a 5-tuple too
strace expects a list of register names and values like
{"PC", *PC, "SP", *SP}
strace returns 5-tuples now:
{fn, pc, callerpc, paramlist, locallist}
new builtin includepipe(cmd) includes the standard output
of running cmd.
symbols returns 4-tuples now: {name, type, addr, file}
new builtin textfile() returns the current set of open text files
as a list of {file, base} pairs.
new builtin textfile({file, base}) adds a new file's symbols and text
offset by base for relocatables.
new builtin deltextfile(file) removes a file from the set of open text files.
both textfile and deltextfile update symbols.

yet to be done:
elflink has the linking info for elf on linux
