apr-util: fix ptest fail problem

Test suite test_dbm failed after gdbm upgrtade to 13.1,
from 13.1, return value of some function are changed.

* gdbm_fetch, gdbm_firstkey, and gdbm_nextkey behavior

If the requested key was not found, these functions return datum with
dptr pointing to NULL and set gdbm_errno to GDBM_ITEM_NOT_FOUND (in
prior releases, gdbm_errno was set to GDBM_NO_ERROR),

+Subject: [PATCH] Fix error handling in gdbm
+
+Only check for gdbm_errno if the return value of the called gdbm_*
+function says so. This fixes apr-util with gdbm 1.14, which does not
+seem to always reset gdbm_errno.
+
+Also make the gdbm driver return error codes starting with
+APR_OS_START_USEERR instead of always returning APR_EGENERAL. This is
+what the berkleydb driver already does.
+
+Also ensure that dsize is 0 if dptr == NULL.
+
+Upstream-Status: Backport[https://svn.apache.org/viewvc?
+view=revision&amp;revision=1825311]
