[Lazarus] FPC move to mantis completed

[Michael Van Canneyt]

Hello,

After several technical issues (8 tries were needed to convert the FPC
sources to git), the move from svn/mantis to gitlab has been completed.

The FPC sources are now available at

https://gitlab.com/freepascal.org/fpc/source

All FPC git repositories are available at:

https://gitlab.com/freepascal.org/fpc

This is also where bugs can be reported from now on:

All Mantis issues have been converted to Gitlab issues.

Depending on where you report an issue, the Gitlab system will ask you to
select a project under which to report a bug.

Note that e.g. documentation bugs should be reported in the documentation
repository:

https://gitlab.com/freepascal.org/fpc/documentation

etc.

A redirect has been put in place for the old bug system, if possible the
system will redirect you to the correct issue in Gitlab.
A similar redirect will be put in place for the viewvc repository view tool.

The "development" page has been updated with the necessary instructions to
connect with Git:
https://www.freepascal.org/develop.html

More information about git has been placed in the WIKI:

https://wiki.freepascal.org/FPC_git

The lazarus team also placed a version at

https://wiki.freepascal.org/SVN_to_GIT_Cheatsheet

If you see places where we overlooked updating the SVN to git or mantis to
gitlab information, please let us know...

Michael.
