29828aa330 Log device opening errors during listing
Without this log, the user would have no way to know that a USB device
is rejected because it could not be opened (typically due to
insufficient permissions).

582161607e Add option to select USB or TCP/IP devices
If several devices are connected (as listed by `adb devices`), it was
necessary to provide the explicit serial via -s/--serial.

If only one device is connected via USB (respectively, via TCP/IP), it
might be convenient to select it automatically. For this purpose, two
new options are introduced:
 - -d/--select-usb: select the single device connected over USB
 - -e/--select-tcpip: select the single device connected over TCP/IP

146f65d7b2 Introduce adb device selector
Currently, a device is selected either from a specific serial, or if it
is the only one connected.

In order to support selecting the only device connected via USB or via
TCP/IP separately, introduce a new selection structure.

5ed13ef477 Execute adb start-server
This does nothing if the adb daemon is already started, but allows to
print any output/errors to the console.

Otherwise, the daemon starting would occur during `adb devices`, which
does not output to the console because the result is parsed.

0a619dc9ef Allow selecting a device from IP without port
Since the previous commit, if a serial is given via -s/--serial (either
a real USB serial or an IP:port), a device is selected if its serial
matches exactly.

In addition, if the user pass an IP without a port, then select any
device with this IP, regardless of the port (so that "192.168.1.1"
matches any "192.168.1.1:port"). This is also the default behavior of
adb.

137d2c9791 Remove confusing sc_str_truncate()
This util function was error-prone:
 - it accepted a buffer as parameter (not necessarily a NUL-terminated
   string) and its length (including the NUL char, if any);
 - it wrote '\0' over the last character of the buffer, so the last
   character was lost if the buffer was not a NUL-terminated string, and
   even worse, it caused undefined behavior if the length was empty;
 - it returned the length of the resulting NUL-terminated string,
   which was inconsistent with the input buffer length.

In addition, it was not necessarily optimal:
 - it wrote '\0' twice;
 - it required to know the buffer length, that is the input string
   length + 1, in advance.

Remove this function, and let the client use strcspn() manually.

6d41c53b61 Fix adb connect parsing
The function assumed that the raw output of "adb connect" 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.

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).

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.
