jwawintype.pas redefines a number of unsigned 64 bit integer types as singed 64 bit integer

## Description:
jwawintype.pas contains the following code:
```
line 128: ULONGLONG = Int64;
line 606: _FLOAT128 = record
LowPart: Int64;
HighPart: Int64;
end;
line 1606: ULONG64 = Int64;
{$EXTERNALSYM ULONG64}
PULONG64 = ^ULONG64;
{$EXTERNALSYM PULONG64}
DWORD64 = Int64;
{$EXTERNALSYM DWORD64}
PDWORD64 = ^DWORD64;
{$EXTERNALSYM PDWORD64}
UINT64 = Int64;
{$EXTERNALSYM UINT64}
PUINT64 = ^UINT64;
{$EXTERNALSYM PUINT64}
```
Code at lines 128 and 1606 redefines the unsigned 64 bit integer types as Int64 which causes compile errors in various places.
In additional information section I have attached the SVN unified diff of how I have resolved the issue:<br/>
Check if UInt64 is already declared and if not declare it as QWord or, as last resort, as Int64.<br/>
All other unsigned integer 64 types are then aliased to UInt64.
