During the MAP_STACK introduction in 2018, sigaltstack() became a
problem because haphazard use could shoot holes in the address space
(changing permissions, providing opportunities for pivoting, etc). I
tried to write a diff to convert the address space correctly but did
not understand enough about map entries, so instead we mapped new
memory over top of the existing object.  Placing a new mapping becomes
unfeasible with the upcoming mimmutable model, so here is code that
adds MAP_STACK to the region.  It will only do so for a contigiously
mapped region that is non-syscall with permission RW, otherwise it
returns an error.
Food for thought: If we know the object isn't service by an object,
we should consider zero'ing the region, to block pre-pivot placement?

Without command and redirection alone, `exec' permanently redirects I/O for
the shell itself, not executing anything;  it is the only (special) builtin
with such a special use-case, implemented as c_sh.c:c_exec().

This corner-case is overlooked in exec.c:execute() which handles iosetup()
failure for all commands, incl. builtins.

Exclude c_exec() from the rest of special builtins to ensure it runs the
ERR trap as expected:

$ ./obj/ksh -c 'trap "echo ERR" ERR ; exec >/'
ksh: cannot create /: Is a directory
ERR
