+ dst and appends a closing NUL to dst.
+ Note that if strlen(src) >= length then dst[length] will be set to \0
+ strmake() returns pointer to closing null

+ 'length' is the maximum length of the string; the buffer needs
+ to be one character larger to accommodate the terminating
+ '\0'. This is easy to get wrong, so we make sure we write to
+ the entire length of the buffer to identify incorrect
+ buffer-sizes. We only initialism the "unused" part of the
+ buffer here, a) for efficiency, and b) because dst==src is
+ allowed, so initializing the entire buffer would overwrite the
+ source-string. Also, we write a character rather than '\0' as
+ this makes spotting these problems in the results easier.
+
+ If we are using purify/valgrind, we only set one character at
+ end to be able to detect also wrong accesses after the end of
+ dst.
