git migration: Remove support for file versions
Git does not support the ability to replace a token with a version
string during check-in. While it does have support for replacing a
token on clone, this is somewhat sub-optimal: the token is replaced
with the object hash, which is not particularly easy for human
consumption. What's more, in practice, the source file version was often
not terribly useful. Generally, when triaging bugs, the overall version
of Asterisk is far more useful than an individual SVN version of a file.
As a result, this patch removes Asterisk's support for showing source file
versions.
Specifically, it does the following:
* main/asterisk:
- Refactor the file_version structure to reflect that it no longer
tracks a version field.
- Alter the "core show file version" CLI command such that it always
reports the version of Asterisk. The file version is no longer
available.
* main/manager: The Version key now always reports the Asterisk version.
* UPGRADE: Add notes for:
- Modification to the ModuleCheck AMI Action.
- Modification of the "core show file version" CLI command.

=== UPGRADE-12.txt -- Upgrade info for 11 to 12
===========================================================
+
+From 13.1-cert2 to 13.1-cert3:
+
+Source Control:
+ - Asterisk has moved from Subversion to Git. As a result, several changes
+ were required in functionality. These are listed individually in the
+ notes below.
+
+AMI:
+ - The 'ModuleCheck' Action's Version key will now always report the
+ current version of Asterisk.
+
+CLI:
+ - The 'core show file version' command has been altered. In the past,
+ this command would show the SVN revision of the source files compiled
+ in Asterisk. However, when Asterisk moved to Git, the source control
+ version support was removed. As a result, the version information shown
+ by the CLI command is always the Asterisk version. This CLI command
+ will be removed in Asterisk 14.
+
From 13.0.0 to 13.1.0:
