e80316cf9a Silence SCARD_E_TIMEOUT warnings
These occur quite often for status calls, so reduce log verbosity.

40f23e2728 SCardReadCache/SCardWriteCache should actually cache data
Currently since the hash/keyCompare/keyClone members on the
context->cache were never being set, we were using the
HashTable_Pointer* variants, meaning that lookup always
failed (since we never ask for the same *pointer* twice).

This also revealed that the logic for autoallocate on these ops
was a bit backwards, and some error codes and support for the
"freshness" counter were missing.

In Win10 (at least with some card minidrivers) the freshness
counter is load-bearing and smartcard login won't work without
implementing a very basic version of it.

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.

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.

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.

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.
