If the size parameter is used with a percentages like /size:50% now
an additional 'w' or 'h' can be appended (like /size:50%w) to specify
where the percentage should be applied. If both or none are set the
behavior is like it was before and the percentage is applied to width
and height.
Adds a callback that allows servers to compute NTLM hashes by themselves. The typical
use of this callback is to provide a function that gives precomputed hash values.

The H264 context is surface specific, so in multi-monitor (with multiple surfaces)
the decoding was failing. This patch fixes that by introducing a surface specific
h264 context.
clipDataId is an optional field of CLIPRDR_FILECONTENTS_REQUEST.
The client should not send it to the server without sending a prior
CLIPRDR_LOCK_CLIPDATA request. The reverse is true as well: the
server should not include these additional 4 bytes without locking
the file in question.
The value zero is a valid ID, it cannot be used as a sentinel value.
Introduce a separate flag to tell whether the clipDataId has been set
and can be relied upon.
Also fix formatting. These stupid line breaks have negative impact on
readability, and the lines do fit into the 100 column limit either way.
To handle a new format we should first be able to transform the format
name from the local clipboard owner into its remote representation. In
our case this will be trasforming the "text/uri-list" target into the
"FileGroupDescriptorW" named format.
Add CB_FORMAT_TEXTURILIST to identify the local format by its ID during
the data conversion step. This numeric ID has nothing to do with the ID
which will be sent to server. It's a bit weird, but that's how XFreeRDP
works.
After that add a new client format with this ID and appropriate local
and remote format names (in atom and formatName fields respectively).
Do this only if wClipboard actually supports "text/uri-list" format.
(It could fail to initialize the local file subsystem, in which case
it will fail all file-related requests and there would be no point in
advertising the file format support in the first place.)
Finally, handle the actual format data request for a new named format
in xf_cliprdr_process_requested_data(). Remember to convert the
FILEDESCRIPTOR array we receive from wClipboard into the
CLIPRDR_FILELIST expected by the server. Also take care to not leak
memory during this conversion.
Note that this handles only the CLIPRDR_FORMAT_DATA_REQUEST. The server
is still not able to retrieve the file content as this is done via a
separate request-reply sequence.
The format is described in MS-RDPECLIP 2.2.5.2.3 Packed File List
(CLIPRDR_FILELIST). These functions handle conversion between the
on-the-wire data from cliprdr and arrays of FILEDESCRIPTOR structs.
FILETIME handling is a bit wacky, but that's what we currently have.
The flags are defined by MS-RDPECLIP 2.2.5.2.3.1 File Descriptor
(CLIPRDR_FILEDESCRIPTOR) as well as by 'File Attribute Constants'
in WinAPI reference [1].
The idea is to delegate FILEDESCRIPTOR format processing to WinPR
instead of cliprdr channel, so move the struct definition there. The
definition used by cliprdr protocol is identical but with some fields
treated as reserved.
The defintions are placed into <winpr/shell.h> as FileGroupDescriptorW
is a shell clipboard format.
Also remove the definition of CLIPRDR_FILELIST. The clients would be
using WinPR to handle the file clipping, so CLIPRDR_FILELIST does not
have to be handled explicitly. The clients will have serialization and
deserialization functions to handle CLIPRDR_FILELIST.

Since this comes via a Wire-To-Surface-2 PDU we don't have
any left/top/right/bottom destination values.
The current code has always dealt with zeros when updating the
invalid region which resulted in black rectangles.
The correct update region is determined during decompression.
This callback is called when the client capabilities have been received. This callback
appears to be more useful than the Capabilities one that is called just before the server
sends its capabilities.
Since not all H264 decoders support multiple YUV420 output
buffers process H264 decoding and YUV to RGB conversion
sequentially to avoid overriding the input data.
Allow password to be stored in .RDP file and parsed and settings
updated, this will allow for dynamic .RDP files to be created with
complete login credentials, using this method the username, server and
password will no longer be visible within process lists.
Also fixed issue of username and domain being read from .RDP files and
set to null by command line processor.
