c070723bc8 Add sc_vector
Adapt vlc_vector [1], that I initially wrote while implementing the VLC
playlist [2].

Change the implementation to use "statement expressions" [3], which are
forbidden in VLC because "non-standard", but:
 - they are supported by gcc and clang;
 - they are already used in the scrcpy codebase;
 - they avoid implementation hacks (VLC_VECTOR_FAILFLAG_);
 - they allow a better API (sc_vector_index_of() may return the result
   without an output parameter).

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.

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.

924375487e Pass buttons state in scroll events
A scroll event might be produced when a mouse button is pressed (for
example when scrolling while selecting a text). For consistency, pass
the actual buttons state (instead of 0).

In practice, it seems that this use case does not work properly with
Android event injection, but it will work with HID mouse.

e2b3968c66 Always synchronize clipboard on explicit COPY/CUT
If --no-clipboard-autosync is enabled, the automatic clipboard
synchronization performed whenever the device clipboard changes is
disabled.

But on explicit COPY and CUT scrcpy shortcuts (MOD+c and MOD+x), the
clipboard should still be synchronized, so that it remains possible to
copy-paste from the device to the computer.

This is consistent with the behavior of MOD+v, which pastes the computer
clipboard to the device.

55806e7d31 Remove option --render-expired-frames
This flag forced the decoder to wait for the previous frame to be
consumed by the display.

It was initially implemented as a compilation flag for testing, not
intended to be exposed at runtime. But to remove ifdefs and to allow
users to test this flag easily, it had finally been exposed by commit
ebccb9f6cc.

In practice, it turned out to be useless: it had no practical impact,
and it did not solve or mitigate any performance issues causing frame
skipping.

But that added some complexity to the codebase: it required an
additional condition variable, and made video buffer calls possibly
blocking, which in turn required code to interrupt it on exit.

To prepare support for multiple sinks plugged to the decoder (display
and v4l2 for example), the blocking call used for pacing the decoder
output becomes unacceptable, so just remove this useless "feature".

d0739911a3 Forward DOWN and UP separately for right-click
The shortcut "back on screen on" is a bit special: the control is
requested by the client, but the actual event injection (POWER or BACK)
is determined on the device.

To properly inject DOWN and UP events for BACK, transmit the action as
a control parameter.

If the screen is off:
 - on DOWN, inject POWER (DOWN and UP) (wake up the device immediately)
 - on UP, do nothing
If the screen is on:
 - on DOWN, inject BACK DOWN
 - on UP, inject BACK UP

A corner case is when the screen turns off between the DOWN and UP
event. In that case, a BACK UP event will be injected, so it's harmless.

As a consequence of this change, the BACK button is now handled by
Android on mouse released. This is consistent with the keyboard shortcut
(Mod+b) behavior.
