VCS-CMSynergy

Changes for version 1.52 - 2020-01-23

BEWARE - USER VISIBLE CHANGE
- Replace new() option --host with option --server
  - --host makes no sense for Synergy 7.2 and above; also drop --ui_database_dir
Bug fixes
- Fix problem with object names that contain the database delimiter
  - This is legal when the attribute allow_delimiter_in_name (on base-1:model:base) is TRUE. In this case (assuming delim "-"), an objectname "foo - bar.txt-1:ascii:1" would get canonicalized to "foo : bar.txt-1:ascii:1" instead of "foo - bar.txt:1:ascii:1".
- :tied_objects: silently omit "source" from the keys of the tied hash
Other changes
- Make "utf8" available as a session option
  - Using $ccm = VCS::CMSynergy->new(utf8 => 1, ...) ensures that all strings retrieved from Synergy using $ccm are Perl unicode strings. Note that this will only work if the Synergy session was actually started in a UTF-8 locale (at least on Linux). Setting e.g. the environment variable LANG *after* starting a session has no effect on Synergy ouput.
- Add a session counter for the number of times "ccm" was executed
- Change implementation of :tied_objects
- Put VCS::CMSynergy::Objects on a diet
  - use an array instead of a hash as implementation
  - no need to inherit from Class::Accessor::Fast anymore
- Weaken the objects in the session's "objects" cache
- Compile all Type::Params validations
  - compile()d validations are not only faster, they don't leak memory like their "ad hoc" variants (i.e. using validate()). The leakage is small (~20 kB per call for some specifications), but may add up if methods are called 100,000 times or more.
  - NOTE: This requires feature 'state', hence bump MIN_PERL_VERSION to 5.10.0.
- Switch from Module::Install to ExtUtils::MakeMaker
