sh: introduce a function to iterate over all aliases

Currently the data structure holding alias information is opaque for
consumers outside alias.c and there is no way to iterate over all
aliases, which will become needed by a future commit.

The new function "iteralias" takes a null pointer to return the first
alias or an existing alias to return the next one, unless there is
no alias to return, in which case it returns a null pointer.

I slightly changed the static function hashalias so that it returns the
index into the array holding link heads, and not the link head directly.
In this form it's easier to use by iteralias and the slight adjustment
in the three existing callers doesn't look too bad.

sh: Remove special code for shell scripts without magic number.

These are called "shell procedures" in the source.

If execve() failed with [ENOEXEC], the shell would reinitialize itself
and execute the program as a script. This requires a fair amount of code
which is not frequently used (most scripts have a #! magic number).
Therefore just execute a new instance of sh (_PATH_BSHELL) to run the
script.

Most of this is adding const keywords, but setvar() in var.c had to be
