To handle special chars, text is handled as text input instead of key
events. However, this breaks the separation of DOWN and UP key events.
As a compromise, send letters and space as key events, to preserve
original DOWN/UP events, but send other text input events as text, to be
able to send "special" characters.

The common command.c handled process errors from system-specific int
values (errno).
Rather, expose a new enum process_result to handle error cause in a
generic way.
There are many user who encounters missing adb.
To stop things happens again, we check it and show
sexy response to user.

The current_process field was never reset after an installation is
complete. As a consequence, installer_stop() attempted to terminate it,
leading to a warning, at best.
In the Android input header file, an enum has a value taking more than
31 bits, leading to the following warning:
ISO C restricts enumerator values to range of ‘int’
Since we don't use it, remove it.
A missing initialization (fixed by the previous commit) leaded to kill
unexpected process.
In order to prevent consequences of similar errors in the future, never
call kill() with a non-positive PID.
See <https://github.com/Genymobile/scrcpy/issues/182>.
The current_process field of struct installer was not initialized.
Since the installer instance is static, its default value was 0.
The call to installer_stop() then called kill(0, SIGTERM) (on Linux),
which sent SIGTERM to every process in the process group. In particular,
the scrcpy process was killed.
As a consequence, the last cleanup steps, like disabling "show touches",
were not executed.

Meson decided to crossbuild for Windows as soon as
meson.is_cross_build() returned true. This made non-Windows crossbuilds
fail.
Instead, add an explicit option "crossbuild_windows".
Fixes <https://github.com/Genymobile/scrcpy/issues/165>.
On Windows, an application is either console or gui, it cannot be both.
Scrcpy should be both: it outputs important information to console, but
we still want to be able to ignore the console and launch it without a
visible cmd.exe window.
Therefore, build two binaries:
- scrcpy.exe
- scrcpy-noconsole.exe
Build the Windows binary from mingw on Linux, using the official
prebuilt binaries for ffmpeg, SDL2 and adb.
MSYS2 and all its packaged dll are not necessary anymore.
In practice, proc_show_touches may not be used uninitialized, since it
checks the flag options->show_touches, but the compiler can't know that,
so initialize it to avoid the warning.
I could not make Ctrl+'+' and Ctrl+'-' work for every keyboard on every
platform.
Instead, use Ctrl+UP and Ctrl+DOWN (like in VLC) to change the volume.
Fixes <https://github.com/Genymobile/scrcpy/issues/103>.
SDL_CreateTexture() is called both during initialization and on frame
size change.
To avoid inconsistent changes to arguments value, factorize them to a
single function create_texture().
Double-clicks were not sent to the device anymore since the
"double-click on black borders" feature.
When a double click occurs inside the device screen, send the event to
the device normally.
Fixes <https://github.com/Genymobile/scrcpy/issues/97>.
Enabling "show touches" involves the execution of an adb command, which
takes some time.
In order to parallelize, execute the command as soon as possible, but
reap the process only once everything is initialized.
If --show-touches is set, then the option must be disabled on quit.
Since it executes an adb command, it takes some time, so close the
window beforehand so that the close window button does not seem
unresponsive.
On H.264 stream EOF, the eof_reached flag is set, but av_read_frame()
still provides a frame, so check the flag only afterwards.
As a side-effect, it also fixes a memory leak (the very last packet was
not unref).
Request SDL not to replace the SIGINT and SIGTERM handlers, so that the
process is immediately terminated on Ctrl+C.
This avoids process hanging on Ctrl+C during network calls on
initialization.
Some of them accepted a timeout, but it was not used since
commit 9b056f5091 anymore.
On Windows and MacOS, resizing blocks the event loop, so resizing events
are not triggered:
- <https://bugzilla.libsdl.org/show_bug.cgi?id=2077>
- <https://stackoverflow.com/a/40693139/1987178>
As a workaround, register an event watcher to render the screen from
another thread.
Since the whole event loop is blocked during resizing, the screen
content is not refreshed (on Windows and MacOS) until resizing ends.
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>
To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.
Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.
Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.
Fixes <https://github.com/Genymobile/scrcpy/issues/5>.
The serial is needed for many server actions, but this is an
implementation detail, so the caller should not have to provide it on
every call.
Instead, store the serial in the server instance on server_start().
This paves the way to implement the "adb forward" fallback properly.
The SDL mouse wheel event seems inconsistent between horizontal and
vertical scrolling.
> Movements to the left generate negative x values and to the right
> generate positive x values. Movements down (scroll backward) generate
> negative y values and up (scroll forward) generate positive y values.
<https://wiki.libsdl.org/SDL_MouseWheelEvent#Remarks>
Reverse the horizontal.
Fixes <https://github.com/Genymobile/scrcpy/issues/49>.
The text input control_event was initially designed for mapping
SDL_TextInputEvent, limited to 32 characters.
For simplicity, the copy/paste feature was implemented using the same
control_event: it just sends the text to paste.
However, the pasted text might have a length breaking some assumptions:
- on the client, the event max-size was smaller than the text
max-length,
- on the server, the raw buffer storing the events was smaller than the
max event size.
Fix these inconsistencies, and encode the length on 2 bytes, to accept
more than 256 characters.
Fixes <https://github.com/Genymobile/scrcpy/issues/10>.
Paste computer clipboard to the device on Ctrl+v.
The other direction (pasting the device clipboard to the computer) is
not implemented. It would require a communication channel from the
device to the computer, other than the socket used by the video stream.
The High DPI support is enabled by default, so that the renderer use the
full definition of High DPI screens.
However, there are still mouse coordinates problems on some MacOS having
High DPI support (but not all), so expose a way to disable it.
The decoder sometimes returned a non-zero value on error, but not on
every path.
Since we never use the value, always return 0 at the end (like in the
controller).
