qsql_odbc: fix SQLGetStmtAtt usage

Failure to initialize the variable can cause spurious non-zero
values.

http://msdn.microsoft.com/en-us/library/windows/desktop/ms715438(v=vs.85).aspx

"..value can either be a SQLULEN value or a null-terminated character
string. If the value is a SQLULEN value, some drivers may only write the
lower 32-bit or 16-bit of a buffer and leave the higher-order
bit unchanged. Therefore, applications should use a buffer of SQLULEN
and initialize the value to 0 before calling this function. Also, the
BufferLength and StringLengthPtr arguments are not used."

Fixed potential invalid memory access in OpenGL engine glyph cache.

We need to clamp glyph_height to prevent from overflowing the texture
cache. A slightly similar issue was fixed for glyph_width in change
9520674b0f02aac55da6. Also, we should only increment the y_offset in
the place where we check for an overflow.

Fixed QLayout::addChildLayout(QLayout *l) when l had a parent

Previously if l had a parent, addChildLayout would warn and skip the
reparenting, but it would still add the sub layout to the layout.
This caused some inconsistencies in the hierarchy which in worst case
could cause crashes.
