This patch replaces the update_web_docs_libstdcxx_svn script, that
updates online documentation from its sources in the GCC repository, run
once a day from cron, with update_web_docs_libstdcxx_git.

	* update_web_docs_libstdcxx_git: New file.
	* update_web_docs_libstdcxx_svn: Remove.
	* crontab: Use update_web_docs_libstdcxx_git.

This patch updates the gcc_release script, used for snapshots and
releases, to use git instead of SVN.

The parts of the changes used in building snapshots have been tested.
The parts used for building releases have not, so it's likely further
fixes may turn out to be needed there when releases are first built
from git.

	* gcc_release: Use git instead of SVN.
	* crontab: Update gcc_release calls.

This patch replaces the update_version_svn script, that updates the
DATESTAMP files from cron, with update_version_git.

	* update_version_git: New file.
	* update_version:svn: Remove.
	* crontab: Use update_version_git.

The FTP protocol is getting long in the tooth, and we should emphasize
HTTPS where that is available. This patch changes various gcc.gnu.org
URL's to instead use HTTPS.

For instance, kernel.org shut down FTP access in 2017, with the
explanation:

- The protocol is inefficient and requires adding awkward kludges to
  firewalls and load-balancing daemons
- FTP servers have no support for caching or accelerators, which has
  significant performance impacts
- Most software implementations have stagnated and see infrequent
  updates
