[OPEN-ILS-DEV] PATCH: utils.[ch] (miscellaneous)

[Scott McKellar]

These patches do several little things:

-- Adds a new macro buffer_length to return the n_used member of a
   growing buffer.

-- Changed buffer_chomp() to return the character removed instead of
   the new string length.

-- Removed the newly obsolete buffer_append_uescape function.

-- In utils.c: removed a commented-out version of the
   OSRF_BUFFER_ADD_CHAR macro, which has long resided in utils.h.

-- In the OSRF_BUFFER_ADD macro: replaced strcat() with strcpy(), as
   I had done earlier in the corresponding function buffer_add().
