Alias dba_popen() to dba_open() until persistent STDIO streams are
implemented.

-Fix memory handling of persistent dba connections.
-Update tests.
# cdb and flatfile still FAIL for dba_popen since the known streams problem

At least this problem exposed some leaks..

Warnings and Notices when lock modifiers for dba_(p)open are used wrong.
This finally closes bug #20828 (and i hope it must not be reopened)

add missing comment

LOCK_EX is not allowed in read mode -> try using existing .lck file in read
only mode only when in read mode.

-remove second attempt to close lock file
-default to lock on db file instead on .lck file.
-try to use existing .lck file and only create it on failure (allows ro access)

Added open modifier '-' to skip/ignore locking. See bug #20828, #20858

Add Berkeley db4 support

Make magic_quotes_runtime work bidirectional for dba

Add magic_quotes_runtime support

Fix locking behaviour: On some systems read during write is permitted but
most libraries are not capable of that. GDBM is system dependant so there
we only test that we do not deadlock.

Use php_flock instead of flock

-fix file open mode when modifier 'd' is used
#Add my name to authors

Emit a warning when open mode modifier t is used wrong.

-Centralise open stream for builtin modules that use streams
-If locks work on database file then only one stream open call is used

finish work on locking
-all but gdbm do internal locking now since only gdbm has internal locking
-you can force locking on database or lck file (with gdbm this makes no
sense so a notic

emalloc never returns 0, so we can simplify the code paths.
also replace ecalloc with emalloc+memset, so that the latter can be inlined.
