__libc_dynarray_emplace_enlarge: Add missing else

2017-09-06T14:03:28+00:00

Before, arrays of small elements received a starting allocation size of
8, not 16.

dynarray: Set errno on overflow-induced allocation failure

2017-08-30T18:10:56+00:00

This allows the caller to return directly on such an error, with an
appropriate errno value.

Add internal facility for dynamic array handling

2017-06-02T09:59:28+00:00

This is intended as a type-safe alternative to obstacks and
hand-written realloc constructs.  The implementation avoids
writing function pointers to the heap.
