8d540e83c7 Fix adb get-serialno parsing
The function assumed that the raw output of "adb get-serialno" was a
NUL-terminated string, but it is not the case.

It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,
if the output was empty, then sc_str_truncate() would write
out-of-bounds.

Avoid the error-prone sc_str_truncate() util function.

2ea12f73db Fix adb getprop parsing

It this output did not end with a space or a new line character, then
sc_str_truncate() would write '\0' over the last character. Even worse,
if the output was empty, then sc_str_truncate() would write

5d6bd8f9cd Fix adb device ip parsing
The parser assumed that its input was a NUL-terminated string, but it
was not the case: it is just the raw output of "adb devices ip route".

In practice, it was harmless, since the output always ended with '\n'
(which was replaced by '\0' on truncation), but it was incorrect
nonetheless.

Always write a '\0' at the end of the buffer, and explicitly parse as a
NUL-terminated string. For that purpose, avoid the error-prone
sc_str_truncate() util function.

5b3ae2cb2f Store actual serial in sc_server
Before starting the server, the actual device serial (possibly its
ip:port if it's over TCP/IP) must be known.

A serial might be requested via -s/--serial (stored in the
sc_server_params), but the actual serial may change afterwards:
 - if none is provided, then it is retrieved with "adb get-serialno";
 - if --tcpip is requested, then the final serial will be the target
   ip:port.

The requested serial was overwritten by the actual serial in the
sc_server_params struct, which was a bit hacky.

Instead, store a separate serial field in sc_server (and rename the one
from sc_server_params to "req_serial" to avoid confusion).

028e7afe32 Assert non-NULL serial

bd3c93ae3d Remove platform-tools installation suggestion
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).

c0a75ca746 Downscale and retry also on early MediaCodec error
The new retry mechanism with a lower definition only worked if the error
occurred during encode(). For example:

    java.lang.IllegalStateException
        at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
        at android.media.MediaCodec.dequeueOutputBuffer(MediaCodec.java:3452)
        at com.genymobile.scrcpy.ScreenEncoder.encode(ScreenEncoder.java:114)
        at com.genymobile.scrcpy.ScreenEncoder.internalStreamScreen(ScreenEncoder.java:95)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:61)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:80)
        at com.genymobile.scrcpy.Server.main(Server.java:255)

However, MediaCodec may also fail before encoding, during configure() or
start(). For example:

    android.media.MediaCodec$CodecException: Error 0xfffffc0e
        at android.media.MediaCodec.native_configure(Native Method)
        at android.media.MediaCodec.configure(MediaCodec.java:1956)
        at android.media.MediaCodec.configure(MediaCodec.java:1885)
        at com.genymobile.scrcpy.ScreenEncoder.configure(ScreenEncoder.java:158)
        at com.genymobile.scrcpy.ScreenEncoder.streamScreen(ScreenEncoder.java:68)
        at com.genymobile.scrcpy.Server.scrcpy(Server.java:28)
        at com.genymobile.scrcpy.Server.main(Server.java:110)

Also downscale and retry in these cases.

38cdcdda50 Improve prebuilt system
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.
