e3d45c4580 fix channel/smartcard: remove SCardAddReaderName
SCardAddReaderName isn't part of the SCard API.

Note: removing this also removes the possibility to redirect single
smartcard readers with /smartcard:READERNAME. However this features
wasn't implemented in a general way and will be re-added as part of
the smart card channel directly.

1e6fea7fa7 fix channel/smartcard: simplify channel variables
Path was not really used and name was duplicated. Use the device->Name
directly.

f8a3e7acd4 fix channel/smartcard: GetStatusChange return code
In case SCardGetStatusChange returned an error the call didn't return
any data but STATUS_NO_MEMORY as the calloc failed. This caused problems
with multiple applications server side (hangs and incorrect behavior).

Now the case when no readers are returned is handed correctly and the
data is also filled and send if the call fails.

46a7538322 fix channel/smartcard: async request handling
The smart card channel tried to mimic mstsc's behavior on if an IRP was
processed synchronously or asynchronously. As the channel uses one thread per
context it could happen, especially with PCSC, that the main
channel thread was blocked waiting for an smart card operation to
complete. To prevent that behavior only call known safe functions in the
main thread (like CreateContext) and call the rest asynchronously.

For example the channel would block if a ListReaders is invoked on
the same context where a GetStatusChange (infinite timeout)
was already pending. Only when a status change happened the channel
would continue.

Note: Due to the one context per thread design it's important that
cancel isn't queued an alway run synchronously. Otherwise a specific
context might lock.

3dc4e283db fix channel/smartcard: return value handling
Device control calls always returned SCARD_S_SUCCESS even if an error
occurred. This caused server side software (including the card manager)
to behave incorrectly.

99c69cde27 fix channel/smartcard: error handling
According to MS-RDPESC the smart card channel must set the IoStatus to
an NTSTATUS in case a encoding or decoding error happens. The smart card
channel did this correctly but the output stream was modified
incorrectly causing the smart card remote manager to stop in error
cases.

smartcard_operations: move handling of call argument into functions

The call argument was only use by static functions and was always equal
to operation->call. Remove the argument and use operation-call directly.

Also put the memory allocation and check into the same place.

6fa3608111 cleanup cmake exports and pkg-config files
With this commit the "exported" components (usable with pkg-config and
cmake find module package)
* winpr - winpr library and headers
* freerdp - core library and headers
* freerdp-client - client specific library
* freerdp-server - server specific library
* rdtk - rdtk headers and library

To allow the installation of multiple different version (different major
number) the include files were moved into the respective sub folder:
freerdp -> freerdp{MAJOR}/freerdp (currently freerdp2/freerdp/)
winpr -> winpr{MAJOR}/winpr (currently winrp1/winpr/)
rdtk -> rdpk{MAJOR}/rdtk (currently rdtk0/rdtk/

The generated pkg-config and cmake find modules now also include the major
version number. Currently the following pkg-config are generated and
installed.
* winpr1
* freerdp2
* freerdp-server2
* freerdp-client2
* rdtk0

As cmake is able to handle multiple versions out of the box the
following can be used to find a specific module:

find_package(WinPR)
find_package(FreeRDP)
find_package(FreeRDP-Server)
find_package(FreeRDP-Client)
find_package(RdTk)

As cmake doesn't automatically resolve dependencies for packages it is
necessary to manually include the requirements. For example if
FreeRDP-Client is required WinPR and FreeRDP need to be included
(find_package) as well.

This commit also fixes the installation when STATIC_CHANNELS are built.
WITH STATIC_CHANNELS all channels are linked into libfreerdp-client, for
this all channels are generated as linker archive and linked together in
the final step. Before the intermediate linker archives were, although
not required and useful, installed. Same applies for server side
channels.
