snap: fix failure on cloning SwiftShader repository

Try launching session manager via dbus first

snapcraft uses '--recursive-submodules' option by default to clone all
dependencies if source-type is 'git'. Therefore the option leads the failure
on cloning the project by 'git-hooks' submodule. In the case, the failure is
asking username/password to do so.

Use 'override-pull' to prevent the issue as the following
1. clone the project w/o submodules.
2. use 'sed' command to remove 'git-hooks' submodule.
3. update submodules

'git-hooks' submodule is not necessary to build the project[1]

Anbox ignores `org.anbox.service` when launching session manager
even if `org.anbox.service` dbus service was present.

This patch tries to start `org.anbox` (i.e. session manager) via
dbus first, if dbus call fails, it then tries to launch session
manager itself.

cmds: add binderfs support to system information output

Migrate IRC channel to libera.chat

New Build Script

Update installation instructions to drop anbox-modules mentions

binderfs support has been add in this commit:
https://github.com/anbox/anbox/commit/92286b81bbcd6b51f1ebce3a4626a0ec6b21e8c4

Do not install cpu_features on make install

xdg desktop directory for anbox category

Add host directory bind mount support in anbox.

cmake: Use FindGMock from cmake-extras

Add "rootless window mode"

Improve performance

This adds rootless mode, in this mode a window wont be created until a
application is started.

Since we already require cmake-extras to build both docker and snap, lets
use FindGMock from there also.

For the amount these functions get called, std copy is way to expensive
to do. This removes the need for buffer to be copied twice, first to a
std::vector then SmallFixedVector. This also directly copies buffer into
a smallVector without the init overhead smallVector's ctor do. This
result is a massive performance bootst (at least on arm devices).

Also use memcpy since that interestingly seems to be faster on arm
devices, on amd64 they seems to be about the same speed.

	Uses bindtab file in anbox data directory to bind directory from host to anbox container.
	Resolve #1754.

ignore directory .vscode

It is a static library anyway, and may conflict with other software
packages in a Linux distribution.

It's old, and basically only works with linux 5.4 lts.

Do break out of while loop
