ole32: Make get_priv_data return target device ptrs (rather than offsets) and add a couple of helper functions to simplify this process.

Remove the untranslated and incomplete STRINGTABLE.

parser_alloc() allocates memory and puts it on a list attached the to query object.
EXPR_sval() frees memory allocated via parser_alloc() on error but does not remove
the pointer from the list, which means that when the query destructor is called it
will be freed again.

TABLE_drop() calls TABLE_remove_column() which calls msi_update_table_columns()
which frees column info and possibly returns without reallocating. When that
happens it will be freed again when TABLE_drop() finally calls free_table().

kernel32: Added GetPrivateProfileSection and GetPrivateProfileString tests for empty section scenario.

amstream/tests: Improve render file test. Move OpenFile specific test into a separate test function.

ws2_32: WSAAddressToStringW should return length of unicode address string should and include the trailing null.

ws2_32: WSAAddressToStringA should return length of ANSI address string and should include the trailing null.

Some drivers apparently need private constants, or don't have an efficient
immval packing. For example, MacOS seems to need 1 float for each different
relative addressing offset. fglrx has the same issue, although it is more
efficient in general

Previously this worked on most drivers because the 16 + 4 reserved int and
bool constants kept the problem hidden. Now that we are more aggressive with
uniforms we have to keep free room for some drivers.

This allows better defining of driver desc fixups without adding extra if
lines for each card.

For starters, there's a fixup for the advertised GLSL constants in ATI cards.
fglrx advertises 512 GLSL uniforms instead of the supported 1024(means 128
instead of 256 vec4's). This bug was confirmed by ATI.
