v1.2.2.1

Release 1.2.2.1 (#3085)

The current versioning scheme of the P4 compiler corresponds to the P4
language specification. In particular, the current compiler version
corresponds to v1.2.2 of P4_16 Language Specification.

This patch updates the P4 compiler version to the following format

	<major>.<minor>.<patchlevel>.<releasenumber>

Where <releasenumber> increments with each release of the compiler.
The increment in version number allows to distribute updates for the
P4 compiler using package management systems such as
DPKG (Debian/Ubuntu) and RPM (Fedora/CentOS).

This change was discussed at the P4 open source developer days on
November 23, 2021.

v1.2.2

Enable automatic release on version change (#2829)

* Use version file

This commit create a VERSION file that can be used to obtain the current
version of P4C.

The current version string "1.2.0+g202103291035~a69e52" contains a semantic
version, date and current git commit. However, the date makes sense only in
packages. Building the same P4C compiler code on a different day should not
result in a different version name. The current git commit is automatically
from the git history.

* ci: rename 'release' action to 'static-build'

This GitHub action doesn't create a release, it only tests if a static
build works on Ubuntu 20.04. Thus, using the name "static build" looks
more accurately describes what it does.

* Enable automatic releases

This GitHub action creates a release in GitHub every time
the Version.txt file has been changed.
