-/* string blocks
-
- I had a couple of choices when deciding upon this data structure.
- gas uses null terminated strings for all its internal work. This
- often means that parts of the program that want to examine
- substrings have to manipulate the data in the string to do the
- right thing (a common operation is to single out a bit of text by
- saving away the character after it, nulling it out, operating on
- the substring and then replacing the character which was under the
- null). This is a pain and I remember a load of problems that I had with
- code in gas which almost got this right. Also, it's harder to grow and
- allocate null terminated strings efficiently.
-
- Obstacks provide all the functionality needed, but are too
- complicated, hence the sb.
-
- An sb is allocated by the caller, and is initialzed to point to an
- sb_element. sb_elements are kept on a free lists, and used when
- needed, replaced onto the free list when unused.
