* /list:smartcard now allows /list:smartcard:<optional> to use different
pkcs11 modules and settings
* /list:kbd-lang now allows /list:kbd-lang:LANG_* to filter languages
All clients can implement their own callbacks for
certificate/credential/smartcard/... but there is a common (default)
implementation for all clients.
with the new setting FreeRDP_UseCommonStdioCallbacks it is now possible
to force these over the client implementation provided ones
The AAD and AVD authentication mechanisms both need an OAuth2 token.
They only differ in the provided arguments, so unify the callbacks into
a single one with variable argument lists.
- Move responsibility for obtaining access tokens to clients
- Add function for getting access tokens for AVD
- Get correct server hostname during AVD setup
- Add utility function for doing http requests
The purpose of clipboard data locking is to make the other peer
retaining the current file list until a pending paste operation is done,
even though the clipboard selection changed.
As it may be difficult to determine, when a lock is needed, imitate the
same behaviour as mstsc:
When the server side supports clipboard data locking, always attempt to
lock the file list on the server regardless of what is advertised in a
FormatList PDU.
The Lock Clipboard Data PDU can even be already sent, before the
Format List Response PDU is sent.
This is also what mstsc, does: First, lock the new (potential) file
list, then unlock the file list, when the pending paste operation is
done.
So, rework the current clipboard implementation in that direction.
Since the implementation for timeouts for old file lists is a bit hard,
for now always force unlock pending locks, when the selection changes.
However, timeouts for old file lists can still be added in the future.
The reworked clipboard handling is done with the help of three hash
tables:
1. The inode table: This hash table manages all inodes for each file.
The keys in this table are the inodes themselves, while the values
the files and directories and their attributes (file size, last write
time, etc.).
2. The clipdata table: This table manages the locks for each file list.
The keys in this table represent the clip data id and the values the
clip data entries, which have a reference to the clip data dir, a
directory containing the whole selection, and some helper attributes,
like the clip data id itself.
3. The request table: Every file size or file range request is managed
here. When a FileContentsRequest is made, its stream id with the
respective details are added to this table. When a response is
received, these details can then be easily looked up here.

"If your application must set the cursor while it is in a window, make sure the class cursor for the specified window's class is set to NULL. If the class cursor is not NULL, the system restores the class cursor each time the mouse is moved."
