81561a242f [host] windows: remove ImpersonateLoggedOnUser call
It shouldn't have any effect, since the host application is created with
the token, and there is no need for the service itself to impersonate.

In practice, removal doesn't appear to have any effect on the ability to
capture privileged things like secure desktop.

789f21ccb3 [host] windows: handle defined exit codes in service
The service should now react to host application exit codes.
For the exit codes that demands it, the service will exit instead of
restarting the host.

72c86d7125 [client] all: add screen rotation support win:rotate
Currently only supports EGL, if there is enough demand for OpenGL
support this can be added later.

Closes #231

323aab8ec2 [host] windows: improve restart logic and remove mutex hack
Use the process handle returned by CreateProcessAsUserA to wait on the
process. This results in faster response times and less polling.
For example, it now restarts instantly when UAC is activated.

This also removes the call to OpenProcess and rendering the mutex unnecessary.

As a bonus, it should fix #298.

22920acc88 [host] windows: define exit codes for future use
The host process will be changed to return these codes, from which the
service process could decide whether to exit or restart the process and log.

Note that on Windows, return values are 32-bit unlike POSIX which is only 8.

afa277f8ee [common] ivshmem/linux: add stubs for ivshmemInit and ivshmemFree
These two functions were added in 9ff1859dc1

Adding stubs will allow the host to compile on Linux.
These should be fixed later.

78cb65a6a4 [client] spice: correctly use fabs for floating point
The prototype for abs is int abs (int n), which implicitly casts floating
point values to integers. The correct function is fabs.

369c49cdcf [client] render/opengl: remove braces so fallthrough comment is recognized

0495f5de26 [client] enable useful extra warnings
-Wno-sign-compare is used to suppress warnings related to comparing signed
values with unsigned ones. It's too pedantic.

-Wunused-parameter is also too pedantic, especially since all parameters
have to be named in C.

Otherwise, -Wextra lets us catch bugs, such as x < 0 for unsigned x.

On gcc, we pass -Wimplicit-fallthrough=2 so it will recognize our fall
through comment.

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.

17691f889b [client] clipboard/wayland: avoid writing back to guest clipboard
Copying rich text from the guest would be turned into plaintext on the client.
Prior to this change, this would be sent back to the guest, overwriting its
clipboard. This made it impossible to copy rich text inside the guest.

This commit detects such self-copies by checking if the receiver is the
current process, and rejecting it.
