[Bug runtime/4706] New: binary strings

[fche at redhat dot com]

We should consider adopting a binary-safe (length+buffer) representation
of strings.  This would allow copying of binary blobs to/from the kernel,
not just those that happen to exclude \0.

We'd need a family of functions to create/process/print them, and the
tapsets may need to be changed (no more strlcpy -- or perhaps our own
Special Improved replacement, ugh.).

Yeah, we had these once and there was much complaining about the differing
string representations between runtime and translator. What has changed to make
them more worthwhile now?

The basic desire is to be able to manipulate binary data coming out of the
$target pointers.  We might make do with new tapset functions like
kernel_hexstring(address,length) and some new parsing/printing operations,
and leave the plain null-terminated strings alone.  Even though that would
halve the potential length of the binary data, that's not so bad.  Or
maybe permit base64 (more compact but slower to use).

This sounds less and less useful with recent developments such as printf ("%*m",
...)
