Ticket #1748: lzma archives with .tlz extention are not recognized as archives

Browse Source 
Attempting to open a .tlz lzma archive fails - error 'xxx.tlz doesn't look like a tar archive'.
If the file is renamed to .tar.lzma, it is opened without problems.

Fix issue: add recognize of '.tlz' extention.

Refactoring: avoid calls of strlen() function
