Macro ST(*) returns pointer to Perl stack. Other Perl functions which use
Perl stack (e.g. eval) may reallocate Perl stack and therefore pointer
returned by ST(*) macro is invalid.

Construction like this:

ST(0) = dbd_db_login6_sv(dbh, imp_dbh, dbname, username, password, attribs) ? &PL_sv_yes : &PL_sv_no;

where dbd_db_login6_sv() driver function calls eval may lead to
reallocating Perl stack and therefore invalidating ST(0) pointer.
So that construction would cause memory corruption as left part of
assignment is resolved prior executing dbd_db_login6_sv() function.

Correct way how to handle this problem: First call dbd_db_login6_sv()
function and then call ST(0) to retrieve stack pointer.

In this patch are fixes all occurrences of such constructions.

When running perl under valgrind I got memory corruption in DBD::ODBC
driver in that dbd_db_login6_sv() function due to above problem.

Exactly same problem was present in Encode module which was fixed in pull
request: dankogai/p5-encode#72

Pull request dankogai#72 fixed memory
corruption but introduced a new memory leak as dst scalar is not mortal
anymore and not every possible exit from every XS function properly release
scalar's memory.

Fix this memory leak by making dst scalar mortal again. To not re-introduce
that memory corruption, first store dst scalar into temporary variable and
then save it into stack via ST(0) macro.
