BPortLink::AttachString() now accepts a length argument, and will no longer send a terminating null byte; LinkMsgReader::ReadString(), however, will make sure the string read is null terminated. Changed client communication code to use FlushWithReply() instead of Flush() and GetNextReply() - there were many bugs and shortcomings in the code, I hope I've fixed them all. Converted ClientFontList.cpp to our coding style (but not completely, the class members are missing). Some more cleanup - I hope Adi will adopt our coding style one day! git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12998 a95241bf-73f2-0310-859d-f6bbb57e9c96

// Description: BAppServerLink provides proxied access to the application's
|
|
// connection with the app_server. It has BAutolock semantics:
|
|
// creating one locks the app_server connection; destroying one
|
|
// unlocks the connection.
