6385b8c162 Move common structs to coords.h

e8a565f9ea Fix touch events HiDPI-scaling
Touch events were HiDPI-scaled twice:
 - once because the position (provided as floats between 0 and 1) were
   converted in pixels using the drawable size (not the window size)
 - once due to screen_convert_to_frame_coords()

One possible fix could be to compute the position in pixels from the
window size instead, but this would unnecessarily round the event
position to the nearest window coordinates (instead of drawable
coordinates).

Instead, expose two separate functions to convert to frame coordinates
from either window or drawable coordinates.

0ba74fbd9a Make scrcpy.h independant of other headers
The header scrcpy.h is intended to be the "public" API. It should not
depend on other internal headers.

Therefore, declare all required structs in this header and adapt
internal code.

e40532a376 Manually position and scale the content
Position and scale the content "manually" instead of relying on the
renderer "logical size".

This avoids possible rounding differences between the computed window
size and the content size, causing one row or column of black pixels on
the bottom or on the right.

This also avoids HiDPI scale issues, by computing the scaling manually.

This will also enable to draw items at their expected size on the screen
(unscaled).

6b1da2fcff Simplify size changes in fullscreen or maximized
If the content size changes (due to rotation for example) while the
window is maximized or fullscreen, the resize must be applied once
fullscreen and maximized are disabled.

The previous strategy consisted in storing the windowed size, computing
the target size on rotation, and applying it on window restoration. But
tracking the windowed size (while ignoring the non-windowed size) was
tricky, due to unspecified order of SDL events (e.g. size changes can be
notified before "maximized" events), race conditions when reading window
flags, different behaviors on different platforms...

To simplify the whole resize management, store the old content size (the
frame size, possibly rotated) when it changes while the window is
maximized or fullscreen, so that the new optimal size can be computed on
window restoration.

6baed8a06f Do not init SDL video subsystem if no display
The SDL video subsystem is not necessary if we don't display the video.

Move the sdl_init_and_configure() function from screen.c to scrcpy.c,

dfed1b250e Replace SDL types by C99 standard types
Scrcpy is a C11 project. Use the C99 standard types instead of the
SDL-specific types:

    SDL_bool -> bool

    UintXX   -> uintXX_t

This allows to avoid very long lines, and all function names are

90a46b4c45 Improve startup time
On startup, the client has to:
 1. listen on a port
 2. push and start the server to the device
 3. wait for the server to connect (accept)
 4. read device name and size
 5. initialize SDL
 6. initialize the window and renderer
 7. show the window

From the execution of the app_process command to start the server on the
device, to the execution of the java main method, it takes ~800ms. As a
consequence, step 3 also takes ~800ms on the client.

Once complete, the client initializes SDL, which takes ~500ms.

These two expensive actions are executed sequentially:

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->|| app_process loads the jar
accept the connection .   ^              ||
                      .   |              ||
                      .   | WASTE        ||
                      .   |  OF          ||
                      .   | TIME         ||
                      .   |              ||
                      .   |              ||
                      .   v              X execution of our java main
connection accepted   |<-----------------| connect to the host
init SDL             ||                  |
                     || ,----------------| send frames
                     || |,---------------|
                     || ||,--------------|
                     || |||,-------------|
                     || ||||,------------|
init window/renderer  | |||||,-----------|
display frames        |<++++++-----------|
(many frames skipped)

The rationale for step 3 occuring before step 5 is that initializing
SDL replaces the SIGTERM handler to receive the event in the event loop,
so pressing Ctrl+C during step 5 would not work (since it blocks the
event loop).

But this is not so important; let's parallelize the SDL initialization
with the app_process execution (we'll just add a timeout to the
connection):

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->||app_process loads the jar
init SDL             ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
accept the connection .                  ||
                      .                  X execution of our java main
connection accepted   |<-----------------| connect to the host
init window/renderer  |                  |
display frames        |<-----------------| send frames
                      |<-----------------|

In addition, show the window only once the first frame is available to
avoid flickering (opening a black window for 100~200ms).

Note: the window and renderer are initialized after the connection is
accepted because they use the device information received from the
device.
