On Windows, adb is provided in the release archive. Most missing adb
issues come from users setting the ADB environment variable to an
incorrect value (on all platforms).
Suggesting to install platform-tools to solve the problem will just make
things worse (there will be one more adb in yet another location).
The function was initially implemented to truncate lines, but was later
generalized to accept custom delimiters. The whole documentation has not
been updated accordingly.

This aims to fix two issues with the previous implementation:
1. the whole content of downloaded archives were extracted, while only
few files are necessary;
2. the archives were extracted in the prebuild-deps/ directory as is.
As a consequence of (2), the actual directory name relied on the root
directory of the archive. For adb, this root directory was always
"platform-tools", so when bumping the adb version, the target directory
already existed and the dependency was not upgraded (the old one had to
be removed manually).
Expose common function to download a file and check its checksum, but
let the custom script for each dependency extract only the needed files
and reorganize the content if necessary.
Add an option --otg to run scrcpy with only physical keyboard and mouse
simulation (HID over AOA), without mirroring and without requiring adb.
To avoid adding complexity into the scrcpy initialization and screen
implementation, OTG mode is implemented totally separately, with a
separate window.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Input events helpers to convert from SDL events to scrcpy events were
implemented in input_manager. To reuse them for OTG mode, move them to
input_events.h.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device disconnection is detected when the video socket closes.
In order to introduce an OTG mode (HID events) without mirroring (and
without server), we must be able to detect USB device disconnection.
This feature will only be used in OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Acksync is used to delay HID events until some request (in practice,
device clipboard synchronization) is acknowledged by the device.
This mechanism will not be necessary for OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device was automatically found by sc_usb_connect(). Instead, expose
a function to find a device from a serial, and let the caller connect to
the device found (if any).
This will allow to list all devices first, then select one device to
connect to.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Use it from accept_device() to simplify (at the cost an additional
allocation for each serial, but it is not important).
It will also be useful in other functions in further commits.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.
In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.
Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.
