Fix tar long names

[creker]

Was using the library to generate debian packages which use Tar inside. Files with names longer than 100 symbols were preventing the package from installing - dpkg couldn't copy the files with the long names. Looking at the specification and Tars generated on Linux with default tools I found several bugs:

• Ustar format supports names up to 100 symbols. That is, if a name is exactly 100 symbols you don't need to write terminating symbol. SharpZipLib truncates names to 99 symbols
• "@LongLink" should have default 644 mode. SharpZipLib doesn't specify it
• "@LongLink" should have user ID, user name, group ID and group name from the entry it belongs to. SharpZipLib doesn't specify them
