ce459c24ce [host] app: wait for space in the frame queue
We must always wait for space in the frame queue so that we do not
overwrite memory that is already queued and may be in use by a client.

e477663a7e [host] app: allow the capture interface to select async or sync mode
While it's correct for DXGI to use a asyncronous waitFrame model, other
capture interfaces such as NvFBC it is not correct. This change allows
the capture interface to specify which is more correct for it and moves
the waitFrame/post into the main thread if async is not desired.

8db4b65dee [host] app: allocate LGMP memory for KVMFRCursor updates without shapes
This changes the host to use a seperate pool of LGMP memory for cursor
positionl updates without shape information helping to prevent
corruption of the shape entries if they are still pending. While this is
not a perfect solution it resolves the issue without making major
changes to LGMP during the RC phase we are currently in.

ada6ada576 [host] app: always send the cursor position to the client
If the guest VM is not showing a cursor when it starts such as on the
Windows login screen, the client never gets the current position of the
cursor, which prevents the client from attempting to send mouse
movements. This change ensures the client gets the mouse location on
startup.

82e10c1b7e [host] app: fix inverted cursor shape logic
We should only advance the pointerIndex if the buffer was not swapped
out for storage. This is to ensure that we do not overwrite cursor
memory that the client(s) may still be using.

e9b009db9f [host] app: fix issue with wrong cursor shape being sent for new clients
When a new cursor shape is provided by the capture interface we need to
retain a copy of it incase a new client connects which will not yet have
the cursor shape. The logic here was flawed causing the wrong shape to
be sent to a new client in some instances.

d36c4f0e83 [host] kvmfr: allow the frame size to exceed the available memory
This change allows the host to still transmit a frame that is truncated
if the IVSHMEM size is too small to allow for a full frame.

fb1b30b728 [host] app: calculate and report the required IVSHMEM size
One of the most common issues reported in the support channels is the
IVSHMEM size being too small. This change adds a calculation to
determine an optimal size and uses the new `os_showMessage` platform
method to display a message box to the user with the error.

a089c4ea32 [host] service: introduce fatal errors for ivshmem failures
Also for failure to parse command line. For these errors, restarting
with exponential backoff will not help: no amount of restarting the
service could possibly make the ivshmem device exist or larger, so
we shouldn't try.

f2c0b8c0b4 [host] allow user to select capture backend
This commit introduces a new option, app:capture, which can be set to
either DXGI or NvFBC to force the host application to use that backend.

This is very useful for testing DXGI on Quadro cards, which would default
to running with NvFBC.

54da11a206 [host] free capture interface on exit
This is needed for proper cleanup.

Freeing the capture interface also avoids a crash when using the NvFBC
backend. This is because we moved the mouse hook removal to nvfbc_free.
If nvfbc_free is not called before we start freeing LGMP memory, the
mouse hook would end up writing the cursor position into an invalid
memory address, causing an access violation.

8e98f863b6 [host] windows: detect whether screensaver is disabled in the guest
This will allow us to add an option to disable the screensaver on the client
when an application in the guest requests it. This behaviour may be useful
when the guest is doing media playback.

a46a3a2668 [all] use explicit void parameter lists
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

b942085e6c [host] don't allocate LGMP_Q_POINTER_LEN cursor shape buffers
There is no need to allocate a buffer for each message as the client is
only required to show the latest version of the cursor. Whie the logic
should prevent cursor corruption, it's not guaranteed, however this is
not a problem as this can only happen if the client is lagging behind
and as such when it gets another update message it will re-read the
now new shape anyway.

7e362050f7 [all] update KVMFR to provide cursor hotspot information
This commit bumps the KVMFR protocol version as it adds additional
hotspot x & y fields to the KVMFRCursor struct. This corrects the issue
of invalid alignment of the local mouse when the shape has an offset
such as the 'I' beam.
