Created by Daniel Nichter on 2013-02-14 and last modified on 2013-02-22

Major changes to VersionCheck.pm:

1) No more $self anywhere. The entire package is procedural.

2) version_check() adds a special instance for the system with id=0.

3) Because of #2, there's no need to check the vc file's mtime; we only need to check every line, i.e. every instance. in the vc file.

4) The vc file is now gotten via version_check_file() and it prefers to be in global dirs like /etc/percona, etc. This way, every user on the system will use the same vc file is possible because some system use random /tmp dirs which means the vc file would always be new, and we don't want that.

5) get_perl_module_version() uses eval "<code snippet>" because unless, for example, the program has already done "use DBD::mysql;" (but none of them do), then $DBD::mysql::VERSION will not be available.

6) If IO::Socket::SSL is installed, we use https; else, use http. Trying both protocols could result in a double wait if https works but v.percona.com isn't responding, in which case, since we don't see what the error is/was, we would blindly try http too when it has no chance of succeeding either. So: 1 protocol, 1 chance at success.

7) Removed PTVCDEBUG and added PTDBUG_VERSION_CHECK instead to make version_check() die 255 when done, so we can do things like "PTDEBUG=1 PTDEBUG_VERSION_CHECK=1 pt-query-digest" and have the tool stop right after v-c stuff.
