Subject: [PATCH 01/17] =?UTF-8?q?GetTickCount()=E3=82=92GetTickCount64()?=
 =?UTF-8?q?=E3=81=AB=E7=BD=AE=E3=81=8D=E6=8F=9B=E3=81=88?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

49日でオーバーフローするGetTickCount()をGetTickCount64()に置き換え。
関連する変数の型をDWORDからULONGLONGに変更し、CheckTimeout()の
DWORDオーバーフロー対策コードを削除して簡略化。

Subject: [PATCH 02/17] =?UTF-8?q?TTL=E3=83=9E=E3=82=AF=E3=83=AD=E3=81=AB64?=
 =?UTF-8?q?=E3=83=93=E3=83=83=E3=83=88=E6=95=B4=E6=95=B0=E5=9E=8B(int64)?=
 =?UTF-8?q?=E3=82=92=E8=BF=BD=E5=8A=A0?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`int64 varname` 構文で64ビット整数変数を宣言できるようにし、
`uptime` コマンドがTypInteger64変数に対して64ビット全体を格納するよう対応。
これにより OS 起動から 49.7 日以上経過した環境でも正確な経過時間計測が可能。

- ttmparse.h/cpp: TypInteger64型追加、式評価器をlong longに変更、
  NewInt64Var/GetIntVal(int*)オーバーロード追加
- ttl.cpp: TTLInt64Decl追加、TTLUptime 64bit対応、ExecCmndにTypInteger64代入処理追加
- tests/wait_timeout.ttl: int64変数を使った経過時間テストを追加

- GetIntVal/GetVarTypeのint*オーバーロードをextern"C"非互換のため削除
- GetIntVal実装をint*シグネチャに戻し、内部でlong longを使用してlong longに truncate
- GetVarType実装をint*シグネチャに戻す
- GetExpressionを直接呼ばないlong long Valローカル変数をint Valに戻す
- TTLWait内のGetExpression呼び出し用Valをlong longに修正
