ac2c62e560 [host] intiialize the app state earlier to prevent ovewriting re-inits
If there is LGMP corruption the LGMP thread will set the state to
REINIT which if this happens early enough will get overwritten if the
inital app state is set too late. Instead set the application initial
state early to avoid this.

9969896876 [host] app: zero the new client sub count
If a new client connects but there has not been a capture timeout the
new client count wont be zeroed on a valid capture. If there is a
timeout later the host will still think there is a new client and
re-send a frame when it should not. This fixes this by reading the value
on a valid frame which zeros the new subs count.

1f24ab0742 [host] nvfbc: avoid waking up pointer thread for no reason
If the wait times out, we used to simply restart the loop, which causes
it to check this->stop and exit if set to true. However, nvfbc_stop
already calls lgSignalEvent, which would wake up the pointer thread to
perform the check, so there is no need to set a timeout on the wait.

3651852430 [host] nvfbc: round pitch to multiple of 128 for dmabuf import
Certain drivers do not support pitches that are not multiples of 128 bytes,
and instead just does some kind of rounding internally. On DXGI, this is not
a problem because the API rounds pixel pitch, but NvFBC does not. This causes
certain resolutions to simply not work with dmabuf, most notably 3440x1440,
which is 1440p ultrawide.

Since we are copying pixels with the CPU anyways, we might as well round the
pitch up to 128 bytes (32 pixels).

4da0c64583 [host] nvfbc: make diff map size configurable
This commit adds a new host configuration option, nvfbc:diffRes, which
specifies the dimensions of every block in the diff map. This defaults to
128, meaning the default 128x128 block size.

Since block sizes other than 128x128 is not guaranteed to be supported by
NvFBC, the function NvFBCGetDiffMapBlockSize was introduced to query the
support and output the actual block size used.

f5dfc264ba [host] windows: trick MinGW into not using memcpy from ntdll
MinGW seems to decide at random whether it wants to use memcpy from

This commit declares a new .def file for ntdll containing only the
functions we want to link from ntdll.dll, and generates ntdll.a from it
with dlltool. This way, MinGW will never be tempted to link functions
like memcpy from ntdll.dll.

5ed3301cf5 [host] nvfbc: merge adjacent changed regions

necessary, but is nevertheless desirable since it reduces the number of
rectangles.
