This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This factors parts of the svn update implementation that are useful for
any globally-versioning vcs tool into cmCTestGlobalVC. It will allow
the code to be shared among the support classes for most vcs tools.
This adds a new VCS update implementation to the cmCTestVC hierarchy and
removes it from cmCTestUpdateHandler. The new implementation has the
following advantages:
- Factorized implementation instead of monolithic function
- Logs vcs tool output as it is parsed (less memory, inline messages)
- Uses one global svn log instead of one log per file
- Reports changes on cvs branches (instead of latest trunk change)
- Generates simpler Update.xml (only one Directory element per dir)
Shared components of the new implementation appear in cmCTestVC and may
be re-used by subclasses for other VCS tools in the future.
This teaches cmCTestSVN::NoteNewRevision to save the repository URL
checked out in the work tree, the repository root, and the path below
the root to reach the full URL.
