Clipboard could not use in win7 or xp about xrdp

[hyeshik]

The problem is due to xrdp's inverse endianness for virtual channel flags to Microsoft's specification. The following patch fixes the issue.

It doesn't work yet. I can't use clipboard sharing(clipboard redirection) after modify and recompile the code.
But, what's worse, rdesktop on Linux which is normal to use clipboard redirection before ,now , clipboard redirection can not be used.

      rdp client (mstsc, rdesktop) --->  xrdp -->  rdp server (windows 2003 terminal server)

Test on:
xrdp: CentOS 5.8 Linux x86_64, FreeRDP-FreeRDP-ac5c7cd, FreeRDP-xrdp-c935eb1 (2012-5-10)
rdp-server: windows 2003, Simplified Chinese.

BEFORE applying hyeshik's patch code
(1) rdp-client: Windows 7 x64, Simplified Chinese. mstsc. FAILED.
(2) rdp-client: rdesktop on CentOS 5.8 Linux x86_64 OK.

AFTER that:
(1) rdp-client: Windows 7 x64, Simplified Chinese. mstsc. FAILED.
(2) rdp-client: rdesktop on CentOS 5.8 Linux x86_64 FAILED.
